Description: Fixed an issue in libsharp where it failed to respond to messages from the SM while searching for Service Records, causing the SM to print timeout messages.

Keywords: sharp_am; openSM

Discovered in Version: 3.1.0

Fixed in Release: 3.4.0

Description: Fixed the issue where sharp_am did not handle hypercube topologies well, causing it to incorrectly treat different switches as duplicates.

Keywords: sharp_am; hypercube

Discovered in Version: 3.3.0

Fixed in Release: 3.4.0

3496440

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.

Description: Fixed the issue of when no sufficient amount of retries was made to resend failed libsharp GroupJoin MADs, SHARP jobs failed before they even started.

Keywords: libsharp; MADs

Discovered in Release: 3.0.0

Fixed in Release: 3.3.0

3393902

Description: Fixed the issue where re-created virtual ports were not recognized by sharp_am, thus the correct tree was not built for them. This resulted in SAT jobs getting  ibv_poll_cq failure in libsharp.

Keywords: Virtual port; sharp_am; libsharp; SAT; ibv_poll_cq 

Discovered in Version: 3.2.0

Fixed in Release: 3.3.0

3404474

Description: Fixed an issue where failure of application allocation of all hosts done via /app/sharp/resources REST-API returned a successful job instead of error.

Keywords: REST API; allocation

Description: Fixed an issue where SHARP AM failed handling reports from OpenSM if some switch ports were down or isolated.

Keywords: Aggregation Manager; Aggregation Node; OpenSM

Discovered in Release: 3.2.0

Fixed in Release: 3.3.0

3236363

Description: Fixed the way physical link failures between switches are handled. In the event of a link failure, a SHARP job utilizing the link has to be stopped; however, this will bear no effect on the other present or future jobs.

Keywords: Aggregation Manager; sharp_am; Link Failure

Discovered in Release: 3.1.0

Fixed in Release: 3.2.0

3230585

Description: Fixed the issue of when operating in Dynamic trees mode, ibdiagnet may have printed warning messages about the existence of multiple distinct trees with the same tree ID.

Keywords: Dynamic tree; ibdiagnet

Discovered in Version: 3.1.0

Fixed in Release: 3.2.0

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.

Fixed in Release: 3.1.0

3163697

Description: Fixed the issue of when the client application used more than 1024 file descriptors (range limit defined by FD_SETSIZE), libsharp was prevented from using any more file descriptors. Using poll() instead of select() enables using the full range of allowed file descriptors by Linux.

2796317

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.

Workaround: The PKEY used for creating the reservation should be "full" (the most significant bit should be on e.g. 0x805c instead of 0x5a).
