- dev
- A newly created DOCA device with same protection domain as 'pd'
Returns
DOCA_SUCCESS - in case of success
Description
Always prefer using a DOCA device obtained from doca_devinfo_create_list() This call will fail if PD was acquired by DOCA through doca_devinfo_create_list() and then doca_rdma_bridge_get_dev_pd()
This API should be used only to bridge between rdma-core and DOCA, to allow them to share memory registrations E.g., application already has logic that utilizes an ibv_pd, to read and write memory using RDMA, and wants to extend the logic by using libraries in DOCA, but such libraries will require a doca_dev and doca_buf instead of an ibv_pd and mkey in order to read write same memory. Then this method can be used to get a doca_dev that can be added to a doca_mmap, such that any doca_buf created from the doca_mmap can yield mkeys that are associated with the same ibv_pd using doca_rdma_bridge_get_buf_mkey()
For reference: doca_dev - is parallel to an ibv_pd doca_buf - is parallel to an ibv_mr registered on multiple devices doca_mmap - is parallel to creating an ibv_mr for multiple devices
The only APIs that are supported for the newly created device:

- doca_error_t doca_rdma_bridge_open_dev_from_pd ( ibv_pd* pd, doca_dev** dev )
-
Open a DOCA device using an ibv_pd.
Parameters
- pd
- A protection domain that is not associated with any DOCA device
- dev
- A newly created DOCA device with same protection domain as 'pd'
Returns
DOCA_SUCCESS - in case of success
Description
Always prefer using a DOCA device obtained from doca_devinfo_create_list() This call will fail if PD was acquired by DOCA through doca_devinfo_create_list() and then doca_rdma_bridge_get_dev_pd()
This API should be used only to bridge between rdma-core and DOCA, to allow them to share memory registrations E.g., application already has logic that utilizes an ibv_pd, to read and write memory using RDMA, and wants to extend the logic by using libraries in DOCA, but such libraries will require a doca_dev and doca_buf instead of an ibv_pd and mkey in order to read write same memory. Then this method can be used to get a doca_dev that can be added to a doca_mmap, such that any doca_buf created from the doca_mmap can yield mkeys that are associated with the same ibv_pd using doca_rdma_bridge_get_buf_mkey()
For reference: doca_dev - is parallel to an ibv_pd doca_buf - is parallel to an ibv_mr registered on multiple devices doca_mmap - is parallel to creating an ibv_mr for multiple devices
The only APIs that are supported for the newly created device:

Can be used with doca_mmap_set_permissions() to set permission level. A few notes: DOCA_ACCESS_FLAG_PCI_READ_ONLY and DOCA_ACCESS_FLAG_PCI_READ_WRITE are mutually exclusive Buffer can always be read locally by local device, regardless of set permissions local device - doca_dev running in the same process of the mmap remote device - doca_dev running on a different process on a remote machine DPU device - doca_dev running on a process on the DPU OS. This is only relevant when local process is running on HOST. In case local process is running on DPU the doca_dev is considered a local device.

This function submits a kernel for launch on the specified `dpa` context. The kernel starts execution when its wait event value is greater than or equal to specified threshold. The completion event is set to value specified in `comp_count` when the kernel finishes execution.
The function to be launched `func` is a host function pointer corresponding to the DPA device function. For example, if the device function is declared as: `__dpa_global__ hello(int arg1)`, then the user is expected to declare the function in the Host application as `extern doca_dpa_func_t hello;`. After the application is linked and loaded using the compiler, a function pointer `hello` can be used in as the `func` argument. The arguments to the function `hello` can be passed inline in the call as var args. For example, to call `hello` on the device using `4` threads with argument `5`, the invocation looks like: `doca_dpa_kernel_launch_update_set(..., 4, hello, 5);`

Description
This function submits a kernel for launch on the specified `dpa` context. The kernel starts execution when its wait event value is greater than or equal to specified threshold. The completion event is set to value specified in `comp_count` when the kernel finishes execution.
The function to be launched `func` is a host function pointer corresponding to the DPA device function. For example, if the device function is declared as: `__dpa_global__ hello(int arg1)`, then the user is expected to declare the function in the Host application as `extern doca_dpa_func_t hello;`. After the application is linked and loaded using the compiler, a function pointer `hello` can be used in as the `func` argument. The arguments to the function `hello` can be passed inline in the call as var args. For example, to call `hello` on the device using `4` threads with argument `5`, the invocation looks like: `doca_dpa_kernel_launch_update_set(..., 4, hello, 5);`

- - DPA Devemu PCI Device DB completion element
Returns
This function returns 1 if there is completion element to return. Otherwise returns 0
Description
The returned completion element will stay valid until it is acked using - doca_dpa_dev_devemu_pci_db_completion_ack Once it is acked then the element should not be used, using it will cause undefined behavior
The expected flow for single DB is as follows: 1. if doca_dpa_dev_devemu_pci_get_db_completion() != 0: 1.1. doca_dpa_dev_devemu_pci_db_completion_element_get_db_properties(&db) 1.2. doca_dpa_dev_devemu_pci_db_completion_ack(1) 1.3. doca_dpa_dev_devemu_pci_db_completion_request_notification() 1.4. doca_dpa_dev_devemu_pci_db_request_notification(db) 1.5. doca_dpa_dev_devemu_pci_db_get_value(db)
The expected flow for multiple DBs is as follows: 1. doca_dpa_dev_devemu_pci_db_t dbs[MAX_NUM_DBS] 2. num_completions = 0 3. while doca_dpa_dev_devemu_pci_get_db_completion() != 0: 3.1. doca_dpa_dev_devemu_pci_db_completion_element_get_db_properties(&dbs[num_completions++]) 4. doca_dpa_dev_devemu_pci_db_completion_ack(num_completions) 5. doca_dpa_dev_devemu_pci_db_completion_request_notification() 6. for db in dbs: (safe to assume that dbs holds unique DBs) 6.1. doca_dpa_dev_devemu_pci_db_request_notification(db) 6.2. doca_dpa_dev_devemu_pci_db_get_value(db)
Failure to follow these steps may result in some unexpected behavior

Description
The returned completion element will stay valid until it is acked using - doca_dpa_dev_devemu_pci_db_completion_ack Once it is acked then the element should not be used, using it will cause undefined behavior
The expected flow for single DB is as follows: 1. if doca_dpa_dev_devemu_pci_get_db_completion() != 0: 1.1. doca_dpa_dev_devemu_pci_db_completion_element_get_db_properties(&db) 1.2. doca_dpa_dev_devemu_pci_db_completion_ack(1) 1.3. doca_dpa_dev_devemu_pci_db_completion_request_notification() 1.4. doca_dpa_dev_devemu_pci_db_request_notification(db) 1.5. doca_dpa_dev_devemu_pci_db_get_value(db)
The expected flow for multiple DBs is as follows: 1. doca_dpa_dev_devemu_pci_db_t dbs[MAX_NUM_DBS] 2. num_completions = 0 3. while doca_dpa_dev_devemu_pci_get_db_completion() != 0: 3.1. doca_dpa_dev_devemu_pci_db_completion_element_get_db_properties(&dbs[num_completions++]) 4. doca_dpa_dev_devemu_pci_db_completion_ack(num_completions) 5. doca_dpa_dev_devemu_pci_db_completion_request_notification() 6. for db in dbs: (safe to assume that dbs holds unique DBs) 6.1. doca_dpa_dev_devemu_pci_db_request_notification(db) 6.2. doca_dpa_dev_devemu_pci_db_get_value(db)
Failure to follow these steps may result in some unexpected behavior

There are 2 data path options to use DOCA ETH RXQ context, a GPU managed control path and a CPU managed one. Other than the need to use doca_ctx_set_datapath_on_gpu() on a GPU context before starting it, both cases share the same control path functions (unless mentioned otherwise in the function documentation). The data path functions are different for the different options. The GPU managed data path functions are not included in the DOCA ETH RXQ API (check DOCA GPUNetIO).

Enumerations
- enum doca_eth_rxq_data_path_type
RX data-path type.
Values
- DOCA_ETH_RXQ_DATA_PATH_TYPE_CPU = 0
- Enable data path management on the CPU
- DOCA_ETH_RXQ_DATA_PATH_TYPE_GPU
- Enable data path management on the GPU
- enum doca_eth_rxq_type
RX queue type.
Values
- DOCA_ETH_RXQ_TYPE_CYCLIC = 0
- This mode is optimized for max packet rate. In this mode the library will receive packets in a cyclic manner. The processing time of packets should be faster than the rate in which they are received. If the application did not process the packets fast enough, the packet may be overrun by a new packet once the recv callback has ended. The receive callback should finish processing the packet before returning or copy the content. The user will supply a doca_mmap for DOCA ETH RXQ context. The recommended size of this mmap should be calculated using doca_eth_rxq_estimate_packet_buf_size.
- DOCA_ETH_RXQ_TYPE_MANAGED_MEMPOOL
- In this mode the library will manage the memory and use various HW features to optimize memory consumption while increasing packet rate. The user will supply a doca_mmap for DOCA ETH RXQ context. The recommended size of this mmap should be calculated using doca_eth_rxq_estimate_packet_buf_size. The library assumes the user will release the packet buffer within a bound amount of time. Keeping packets for a long time without freeing it will block receiving incoming packets. NOTE: This type is supported only for DOCA ETH RXQ instance for CPU
- DOCA_ETH_RXQ_TYPE_REGULAR
- In this mode the user posts a receive task, telling DOCA_RXQ to which buffer to scatter the incoming packet. NOTE: This type is supported only for DOCA ETH RXQ instance for CPU

DOCA ETH TXQ CPU Data Path
DOCA ETH TXQ GPU Data Path
2.13.2. DOCA ETH TXQ
[ DOCA ETH ]
DOCA ETH TXQ library.
There are 2 data path options to use DOCA ETH TXQ context, a GPU managed control path and a CPU managed one. Other than the need to use doca_ctx_set_datapath_on_gpu() on a GPU context before starting it, both cases share the same control path functions (unless mentioned otherwise in the function documentation). The data path functions are different for the different options. The GPU managed data path functions are not included in the DOCA ETH TXQ API (check DOCA GPUNetIO).

- Similarly to doca_eth_txq_calculate_timestamp() it returns the wait on time value to use with doca_gpu_dev_eth_txq_wait_time_enqueue_* functions. It works only if wait on time support on the txq is DOCA_ETH_WAIT_ON_TIME_TYPE_NATIVE.
- __device__ doca_error_t doca_gpu_dev_eth_txq_commit_strong ( doca_gpu_eth_txq* eth_txq )
- Create a commit point in the send queue. Must be invoked after enqueuing multiple items in the send queue with doca_gpu_dev_eth_txq_*_enqueue_strong() functions. After this function the doca_gpu_dev_eth_txq_push should be invoked. It's discouraged but not prohibited to invoke more doca_gpu_dev_eth_txq_send_enqueue_strong() and then another doca_gpu_dev_eth_txq_commit_strong() right after. Only one thread can invoke this function after a sequence of doca_gpu_dev_eth_txq_send_enqueue_strong() invoked by multiple threads.

It's developer responsibility to enqueue the doca_gpu_buf in sequential position with respect to other doca_gpu_buf or barriers enqueued by other CUDA threads in the queue. Multiple CUDA threads can invoke this function on the same queue to enqueue doca_gpu_buf simultaneously in different positions.
- __device__ doca_error_t doca_gpu_dev_eth_txq_wait_completion ( doca_gpu_eth_txq* eth_txq, uint32_t num_sends, doca_gpu_dev_eth_txq_wait_flags wait_mode, uint32_t* num_completed )

- Enqueue a time barrier in the send queue: packets enqueue after this point will be sent by the network card in the future at the specified timestamp. This function must be invoked per-thread. Reserved for advanced developers as it allows to specify at which position the barrier should be placed in the send queue. It's developer responsibility to enqueue barrier in sequential position wrt other doca_gpu_buf or barriers avoiding empty elements in the queue. Multiple threads can invoke this function on the same queue to enqueue barriers simultaneously in different positions.
Enumerations
- enum doca_gpu_dev_eth_txq_wait_flags
Eth Txq wait modes
Values
- DOCA_GPU_ETH_TXQ_WAIT_FLAG_NB = 0
- Non-Blocking mode: the wait completion function doca_gpu_dev_eth_txq_wait_completion checks if the input number of send operations completed (data has been sent) and exit from the function. If nothing has been sent, the function doesn't block the execution.
- DOCA_GPU_ETH_TXQ_WAIT_FLAG_B = 1
- Blocking mode: the wait completion function doca_gpu_dev_eth_txq_wait_completion blocks the execution waiting for all the input send operations to be completed.
- enum doca_gpu_send_flags
Set of properties to enable when pushing a new element in a send queue.
Values
- DOCA_GPU_SEND_FLAG_NONE = 0
- No specific property must be enabled. Best configuration to enhance the performance.
- DOCA_GPU_SEND_FLAG_NOTIFY = 1<<0
- Return a notification when a send or wait item is actually executed. Please note this is requires the DOCA PE on the CPU side to check the Eth Txq context (send queue) and cleanup every notification (can be set via doca_eth_txq_gpu_event_notify_send_packet_register function). For this reason, this flag should be set mostly for debugging purposes as it may affect the overall performance if CPU is not fast enough to query and cleanup the notifications.
Functions

-
Similarly to doca_eth_txq_calculate_timestamp() it returns the wait on time value to use with doca_gpu_dev_eth_txq_wait_time_enqueue_* functions. It works only if wait on time support on the txq is DOCA_ETH_WAIT_ON_TIME_TYPE_NATIVE.

- Similarly to doca_eth_txq_calculate_timestamp() it returns the wait on time value to use with doca_gpu_dev_eth_txq_wait_time_enqueue_* functions. It works only if wait on time support on the txq is DOCA_ETH_WAIT_ON_TIME_TYPE_NATIVE.
- __device__ doca_error_t doca_gpu_dev_eth_txq_commit_strong ( doca_gpu_eth_txq* eth_txq )
- Create a commit point in the send queue. Must be invoked after enqueuing multiple items in the send queue with doca_gpu_dev_eth_txq_*_enqueue_strong() functions. After this function the doca_gpu_dev_eth_txq_push should be invoked. It's discouraged but not prohibited to invoke more doca_gpu_dev_eth_txq_send_enqueue_strong() and then another doca_gpu_dev_eth_txq_commit_strong() right after. Only one thread can invoke this function after a sequence of doca_gpu_dev_eth_txq_send_enqueue_strong() invoked by multiple threads.
- __device__ doca_error_t doca_gpu_dev_eth_txq_commit_weak ( doca_gpu_eth_txq* eth_txq, const uint32_t elements )

- __device__ doca_error_t doca_gpu_dev_eth_txq_get_info ( doca_gpu_eth_txq* eth_txq, uint32_t* curr_position, uint32_t* mask_max_position )
- Get latest occupied position in the send queue and max position index that can be used in the queue. Highly recommended to use in case of weak send pattern. Please ensure to query this function before starting to enqueue packets in weak mode. The library updated the curr_position value after every doca_gpu_dev_eth_txq_commit_*() The position index should be always masked with mask_max_position value.
- __device__ doca_error_t doca_gpu_dev_eth_txq_push ( doca_gpu_eth_txq* eth_txq )
- Flush the queue sending packets enqueued. Must be invoked right after doca_gpu_dev_eth_txq_commit_strong() or doca_gpu_dev_eth_txq_commit_weak(). Only one thread can invoke this function.

- Enqueue a new packet on the send queue using the GPU handler of an Ethernet txq object. This function must be invoked per-thread. Each invocation of this function will reserve the next descriptor of the send queue for the doca_gpu_buf that must be sent. With this "strong" version, developer doesn't have to worry about send queue management. Multiple threads can invoke this function on the same queue to enqueue multiple packets simultaneously.
- __device__ doca_error_t doca_gpu_dev_eth_txq_send_enqueue_weak ( const doca_gpu_eth_txq* eth_txq, const doca_gpu_buf* buf_ptr, const uint32_t nbytes, const uint32_t position, const uint32_t flags_bitmask )
- Enqueue a new packets on the send queue using the GPU handler of an Ethernet txq object. This function must be invoked per-thread. Reserved for advanced developers as it allows to specify at which position the doca_gpu_buf should be placed in the send queue. It's developer responsibility to enqueue the doca_gpu_buf in sequential position with respect to other doca_gpu_buf or barriers enqueued by other CUDA threads in the queue. Multiple CUDA threads can invoke this function on the same queue to enqueue doca_gpu_buf simultaneously in different positions.
- __device__ doca_error_t doca_gpu_dev_eth_txq_wait_completion ( doca_gpu_eth_txq* eth_txq, uint32_t num_sends, doca_gpu_dev_eth_txq_wait_flags wait_mode, uint32_t* num_completed )

- Enqueue a time barrier in the send queue: packets enqueue after this point will be sent by the network card in the future at the specified timestamp. This function must be invoked per-thread. With this "strong" version, developer doesn't have to worry about send queue management. Multiple threads can invoke this function on the same queue to enqueue barriers simultaneously.
- __device__ doca_error_t doca_gpu_dev_eth_txq_wait_time_enqueue_weak ( doca_gpu_eth_txq* eth_txq, const uint64_t wait_on_time_value, const uint32_t position, const uint32_t flags_bitmask )
- Enqueue a time barrier in the send queue: packets enqueue after this point will be sent by the network card in the future at the specified timestamp. This function must be invoked per-thread. Reserved for advanced developers as it allows to specify at which position the barrier should be placed in the send queue. It's developer responsibility to enqueue barrier in sequential position wrt other doca_gpu_buf or barriers avoiding empty elements in the queue. Multiple threads can invoke this function on the same queue to enqueue barriers simultaneously in different positions.
Enumerations
- enum doca_gpu_dev_eth_txq_wait_flags
Eth Txq wait modes
Values
- DOCA_GPU_ETH_TXQ_WAIT_FLAG_NB = 0
- Non-Blocking mode: the wait completion function doca_gpu_dev_eth_txq_wait_completion checks if the input number of send operations completed (data has been sent) and exit from the function. If nothing has been sent, the function doesn't block the execution.
- DOCA_GPU_ETH_TXQ_WAIT_FLAG_B = 1
- Blocking mode: the wait completion function doca_gpu_dev_eth_txq_wait_completion blocks the execution waiting for all the input send operations to be completed.
- enum doca_gpu_send_flags
Set of properties to enable when pushing a new element in a send queue.
Values
- DOCA_GPU_SEND_FLAG_NONE = 0
- No specific property must be enabled. Best configuration to enhance the performance.
- DOCA_GPU_SEND_FLAG_NOTIFY = 1<<0
- Return a notification when a send or wait item is actually executed. Please note this is requires the DOCA PE on the CPU side to check the Eth Txq context (send queue) and cleanup every notification (can be set via doca_eth_txq_gpu_event_notify_send_packet_register function). For this reason, this flag should be set mostly for debugging purposes as it may affect the overall performance if CPU is not fast enough to query and cleanup the notifications.
Functions
- __device__ doca_error_t doca_gpu_dev_eth_txq_calculate_timestamp ( const doca_gpu_eth_txq* eth_txq, const uint64_t timestamp_ns, uint64_t* wait_on_time_value )
-
Similarly to doca_eth_txq_calculate_timestamp() it returns the wait on time value to use with doca_gpu_dev_eth_txq_wait_time_enqueue_* functions. It works only if wait on time support on the txq is DOCA_ETH_WAIT_ON_TIME_TYPE_NATIVE.

Description
This function initializes an algo data-structure. Each algorithm has in index (not to be confused with the doca_pcc_dev_algo_meta_data::algo_id) Algo database includes a metadata area containing basic algo information, and a params and counters metadata area. The number of parameters and counters is configurable at init time. The space allocated for the algo data-structure using this function is visible to the PCC infrastructure. This is required to allow the infrastructure to read/update param / counter information directly when handling PPCC MADs or commands. The user can use additional memory by allocating global variables
This function should be called once per algo during init.

DOCA Telemetry NetFlow
2.24.1. DOCA Telemetry NetFlow
[ DOCA Telemetry Exporter ]
DOCA lib for exporting a netflow packet to a netflow collector through the telemetry service.
This lib simplifies and centralizes the formatting and exporting of netflow packets. Netflow is a protocol for exporting information about the device network flows to a netflow collector that will aggregate and analyze the data. After creating conf file and invoke init function, the lib send function can be called with netflow struct to send a netflow packet with the format to the collector of choice specified in the conf file. The lib uses the netflow protocol specified by cisco.
See also:
https://netflow.caligare.com/netflow_v9.htm
Limitations:
The lib supports the netflow V9 format. The lib is not thread safe.

Description
2.24.1. DOCA Telemetry NetFlow
[ DOCA Telemetry Exporter ]
DOCA lib for exporting a netflow packet to a netflow collector through the telemetry service.
This lib simplifies and centralizes the formatting and exporting of netflow packets. Netflow is a protocol for exporting information about the device network flows to a netflow collector that will aggregate and analyze the data. After creating conf file and invoke init function, the lib send function can be called with netflow struct to send a netflow packet with the format to the collector of choice specified in the conf file. The lib uses the netflow protocol specified by cisco.
See also:
https://netflow.caligare.com/netflow_v9.htm
Limitations:
The lib supports the netflow V9 format. The lib is not thread safe.

Description
The PCI latency histogram defines a number of time-bound buckets into which the number of PCI read operations that completed within the timeframe of a given bucket are recorded.
For example if the latency histogram was 4 buckets of 500 nanoseconds each: +-------------------+-------------------+-------------------+-------------------+ | bucket_arr[0] | bucket_arr[1] | bucket_arr[2] | bucket_arr[3] | | [0-499]ns | [500-999]ns | [1000-1499]ns | [1500-inf)ns | +-------------------+-------------------+-------------------+-------------------+
When each PCI read operation completes; its latency is compared to the bucket dimensions and the appropriate counter is incremented. For example if a PCI read operation completed in 502ns then bucket_arr[1] would be incremented. If another request took 3000ns then bucket_arr[3] would be incremented.

Description
The UROM Service runs on a DOCA Device. A Service manages UROM Workers which run on the Device. A Worker runs UROM Plugins which implement application logic which runs on the Device.
A Service is created in state `DOCA_CTX_STATE_IDLE`. After creation, a user may configure the Service using setter methods (e.g. `doca_urom_service_set_dev()`). Before use, a Service must be transitioned to state `DOCA_CTX_STATE_RUNNING` using the `doca_ctx_start()` interface. A typical invocation looks like:
`doca_ctx_start(doca_urom_service_as_ctx(service_ctx))`

2.28.2. DOCA UROM Environment Variables
[ DOCA UROM (Unified Resource and Offload Manager) ]
DOCA UROM Environment Variables.
DOCA UROM environment variables are described in the following table.
Variable | Description ------------- | ------------- DOCA_UROM_SERVICE_FILE | Path to the UROM Service File.
DOCA_UROM_SERVICE_FILE
This variable sets the path to the UROM Service File. When creating a UROM Service, UROM performs a look up using this file, the hostname where an application is running, and the PCI address of the associated DOCA device to identify the network address, and network devices associated with the UROM Service.
This file contains one entry per line describing the location of each UROM Service that may be used by UROM. The format of each line must be as follows:
{.unparsed}
<app_hostname> <service_type> <dev_hostname> <dev_pci_addr> <net,devs>
Fields are described in the following table.
{.unparsed}
| Field | Description |
| ------------- | ----------- |
| app_hostname | Network host name (or IP address) for the node that this line applies to. |
| service_type | The UROM service type. Valid type is `dpu`. Type `dpu` is used for all DOCA Devices. |
| dev_hostname | Network host name (or IP address) for the associated DOCA device. |
| dev_pci_addr | PCI address of the associated DOCA device. This must match the PCI address provided by DOCA. |
| net,devs | Comma-separated list of network devices which are shared between the host and DOCA device. |
As an example, an application running on a single node (named app_host1) which has a UROM Service running on DPU (named dpu_host1) would have a Service Directory file with the following entries:
app_host1 dpu dpu_host1 03:00.0 dev1:1,dev2:1

Description
Worker ID must be unique to a UROM Service. If DOCA_UROM_WORKER_ID_ANY is specified, the Service will assign a unique ID for the newly created worker.
If a specific ID is used, the Service will look for an existing Worker with matching ID. If one exists, the Service will establish a new connection to the existing Worker. If a matching Worker does not exist, a new Worker will be created with the specified Worker ID.
Parallel tasks can coordinate by using a convention for worker_id which includes task ID and worker index. task ID should come from a launcher. Worker index can be derived using a local process rank (also from a launcher) and the desired number of workers. The number of workers should be based on the number of available cores for offload, which can be queried through DOCA UROM. The process for setting up workers is then:
1. Query DOCA UROM for available cores on the Service 2. Query launcher for task_id and local_rank 3. Derive ID: worker_id = task_id << 32 | (local_rank % cores) 4. Create a new Worker context with the derived worker_id

2.28.4. DOCA UROM Worker Tasks
[ DOCA UROM (Unified Resource and Offload Manager) ]
DOCA UROM Worker Task interfaces and data structures.
There is one main type of Worker task called a Command task. A Command task defines a plugin and a payload. The Command payload is passed to the plugin running on the associated UROM Worker. Individual plugins define the payload format and behavior of each Command. Optionally, a Command task may return some plugin-defined response data upon completion.
As an example, an RDMA plugin may define a Command to perform an offloaded RDMA Send. The plugin defines the arguments required to offload the Send to the Worker. In order to perform this operation, a Command task is created and formatted to describe the Send. The user then submits the Task to initiate the operation.

2.28.2. DOCA UROM Environment Variables
[ DOCA UROM (Unified Resource and Offload Manager) ]
DOCA UROM Environment Variables.
DOCA UROM environment variables are described in the following table.
Variable | Description ------------- | ------------- DOCA_UROM_SERVICE_FILE | Path to the UROM Service File.
DOCA_UROM_SERVICE_FILE
This variable sets the path to the UROM Service File. When creating a UROM Service, UROM performs a look up using this file, the hostname where an application is running, and the PCI address of the associated DOCA device to identify the network address, and network devices associated with the UROM Service.
This file contains one entry per line describing the location of each UROM Service that may be used by UROM. The format of each line must be as follows:
{.unparsed}
<app_hostname> <service_type> <dev_hostname> <dev_pci_addr> <net,devs>
Fields are described in the following table.
{.unparsed}
| Field | Description |
| ------------- | ----------- |
| app_hostname | Network host name (or IP address) for the node that this line applies to. |
| service_type | The UROM service type. Valid type is `dpu`. Type `dpu` is used for all DOCA Devices. |
| dev_hostname | Network host name (or IP address) for the associated DOCA device. |
| dev_pci_addr | PCI address of the associated DOCA device. This must match the PCI address provided by DOCA. |
| net,devs | Comma-separated list of network devices which are shared between the host and DOCA device. |
As an example, an application running on a single node (named app_host1) which has a UROM Service running on DPU (named dpu_host1) would have a Service Directory file with the following entries:
app_host1 dpu dpu_host1 03:00.0 dev1:1,dev2:1

Description
Worker ID must be unique to a UROM Service. If DOCA_UROM_WORKER_ID_ANY is specified, the Service will assign a unique ID for the newly created worker.
If a specific ID is used, the Service will look for an existing Worker with matching ID. If one exists, the Service will establish a new connection to the existing Worker. If a matching Worker does not exist, a new Worker will be created with the specified Worker ID.
Parallel tasks can coordinate by using a convention for worker_id which includes task ID and worker index. task ID should come from a launcher. Worker index can be derived using a local process rank (also from a launcher) and the desired number of workers. The number of workers should be based on the number of available cores for offload, which can be queried through DOCA UROM. The process for setting up workers is then:
1. Query DOCA UROM for available cores on the Service 2. Query launcher for task_id and local_rank 3. Derive ID: worker_id = task_id << 32 | (local_rank % cores) 4. Create a new Worker context with the derived worker_id

2.28.4. DOCA UROM Worker Tasks
[ DOCA UROM (Unified Resource and Offload Manager) ]
DOCA UROM Worker Task interfaces and data structures.
There is one main type of Worker task called a Command task. A Command task defines a plugin and a payload. The Command payload is passed to the plugin running on the associated UROM Worker. Individual plugins define the payload format and behavior of each Command. Optionally, a Command task may return some plugin-defined response data upon completion.
As an example, an RDMA plugin may define a Command to perform an offloaded RDMA Send. The plugin defines the arguments required to offload the Send to the Worker. In order to perform this operation, a Command task is created and formatted to describe the Send. The user then submits the Task to initiate the operation.

2.28.5. DOCA UROM Domains
[ DOCA UROM (Unified Resource and Offload Manager) ]
DOCA UROM Domain interfaces and data structures.
The UROM Domain represents a collection of UROM Workers working in coordination. Each Worker in the Domain provides a set of memory resources during creation. When the Domain is initialized, memory descriptors are exchanged between all Workers. Workers within a Domain may communicate directly using exchanged these memory descriptors.
Domain initialization is a collective operation. The user is responsible to provide a mechanism for non-blocking allgather communication among all processes which participate in the Domain.
A Domain is only required when using Worker plugins which implement a parallel communication model.
