Please note: As with future releases in the 1.4.x series, this release has largely been limited to bugfixes and incremental improvements of existing code. Active feature development has already started (and has been going on for awhile now, truthfully) on what will eventually be the development branch for a future 1.5 release.
There will, however, be a 1.4.4 release coming up in the very near future (hopefully) to address some of the still-outstanding bugs/issues in the 1.4.x tree. 1.4.3 is being released largely "as-is" due to the massive volume of real-world production testing the current codebase has received, making it as "rock-solid" reliable as one could hope!
New Features:
- Toggle BASH tracing or NHC debugging via
SIGUSR1/SIGUSR2, respectively check_nvsmi_healthmon(): New check from CSC for GPU health monitoring vianvidia-smi
Fixes/Improvements:
- Corrections/cleanups of SGE integration support
- Provide added detail to tracing info (
-xmode) - Based on feedback from Moe Jette of SchedMD, pull node job data directly from Slurm via
squeueinstead of the previous method that only worked for single-node jobs. - Support for recent additions to the Slurm node states (e.g., "planned")
- Pathname expansion has been disabled on startup, and re-enabled only when being actively used, to avoid "unintended" expansions of wildcards at random points throughout the code.
- Correct clobbering of BASH built-in variables and add tests to prevent future recurrence
- Switch "system UID" boundary handling to a more accurate source of truth, and ensure that the code matches the math, naming, and intent.
- Reorder resource manager detection to improve accurate detection, especially with respect to Slurm vs. PBS (all variants)
