7.40. CUpti_ActivityJit

struct CUpti_ActivityJit

The activity record for JIT operations.

This activity represents the JIT operations (compile, load, store) of a CUmodule from the Compute Cache. Gives the exact hashed path of where the cached module is loaded from, or where the module will be stored after Just-In-Time (JIT) compilation.

JIT activity is now reported using CUpti_ActivityJit2 record

Public Members

CUpti_ActivityKind kind

The activity record kind must be CUPTI_ACTIVITY_KIND_JIT.

CUpti_ActivityJitEntryType jitEntryType

The JIT entry type.

CUpti_ActivityJitOperationType jitOperationType

The JIT operation type.

uint32_t deviceId

The device ID.

uint64_t start

The start timestamp for the JIT operation, in ns.

A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the JIT operation.

uint64_t end

The end timestamp for the JIT operation, in ns.

A value of 0 for both the start and end timestamps indicates that timestamp information could not be collected for the JIT operation.

uint32_t correlationId

The correlation ID of the JIT operation to which records belong to.

Each JIT operation is assigned a unique correlation ID that is identical to the correlation ID in the driver or runtime API activity record that launched the JIT operation.

uint32_t padding

Internal use.

uint64_t jitOperationCorrelationId

The correlation ID to correlate JIT compilation, load and store operations.

Each JIT compilation unit is assigned a unique correlation ID at the time of the JIT compilation. This correlation id can be used to find the matching JIT cache load/store records.

uint64_t cacheSize

The size of compute cache.

const char *cachePath

The path where the fat binary is cached.
