3844898 |
Description: Fixed the issue where sharp_am failed to allocate resources for new job requests due to scattered links and unmatched trees, despite a sufficient number of links available. |
|
Keywords: SHARP, Report No resource |
|

Discovered in Release: 3.5.1 |
|
|
Fixed in Release: 3.7.0 |
|
|
3696666 |
Description: Fixed the issue where libsharp could not communicate with sharp_am on systems that exclusively used IPv6 addresses without IPv4 addresses. Now, both libsharp and sharp_am can utilize either IPv4 or IPv6, depending on the machine configuration. |

Fixed in Release: 3.7.0 |
|
|
3686321 |
Description: When upgrading UFM from previous versions to UFM 6.15.x, sharp_am persistent directory as mentioned in the configuration file directs to a path that does not exist. This leads to failure in saving reservation and job information, so in case of a restart of sharp_am, it won’t be able to retrieve required information and return to its previous state. |

Discovered in Release: 3.4.0 |
|
|
Fixed in Release: 3.5.0 |
|
|
3541153 |
Description: Fixed an issue where client application is abnormally terminated before the sharp_coll_finalize method, sharp_am is supposed to automatically detect and clean the job resources. However, with UCX, only one such termination is detected per cycle, leading to incomplete job cleaning. Similarly, when using NCCL and hosts with multiple GPUs/HCAs, each HCA gets its own SHARP job, which results in sharp_am taking several cycles to detect all the jobs that require cleaning. As a consequence, hosts operating in the previous application cannot initiate a new SHARP job until sharp_am detects and cleans all the necessary jobs. |

Description: Fixed the issue in sharp_am where excessive log messages were printed for each disconnected or restarted compute host. Now, the information is printed in a consolidated manner in the form of summaries of disconnected hosts or a list of those hosts in a single log message. However, for more comprehensive details, the complete list of hosts is still available and printed at the DEBUG level. |

3226743 |
Description: Fixed the issue of when a management host was not connected to a leaf switch, sharp_am might have printed a number of warning messages about trees that could not reach all aggregation nodes. As of SHARP v3.2.0, the active management host is automatically identified and is not treated as a potential compute host. However, please note that this does not include standby management hosts for which a warning message would still appear. These management hosts can be mentioned in a list of GUIDs to ignore via the parameter ignore_host_guids_file. |

Description: SHARP jobs may hang when running in reservations mode (i.e. SHARP allocation is enabled), and reservation is created with limited PKEY, and configuring reservation PKEY on tree is enabled. |
