If a job needed to preempt other jobs to start and those jobs were not completed by the time of the next scheduling cycle, other jobs might be selected for preemption in that next cycle resulting in more jobs being preempted than necessary.

Add flag to the select APIs for job suspend/resume indicating if the action is for gang scheduling or an explicit job suspend/resume by the user. Only an explicit job suspend/resume will reset the job's priority and make resources exclusively held by the job available to other jobs. This change is also needed for Cray systems with ALPS.

For front-end architectures on which job steps are run (emulated Cray and BlueGene systems only), fix bug that would free memory still in use.

Processes suspended and resumed are determined by using process group ID and parent process ID, so some processes may be missed. Since salloc runs as a normal user, it's ability to identify processes associated with a job is limited.

The original logic had a problem if you shrank a job and later grew it. Nodes previously released would reappear when the job grows, but have zero CPUs associated with them. The problem was due to the original nodes list of a job being preserved in the job_resources data structure. The new logic confirms that those nodes are still in the job's allocation before rebuilding the job_resources data structure.

Add support to salloc for a new environment variable SALLOC_KILL_CMD, which is equivalent to the -K/--kill-command option.
-
Moe Jette authored
This fixes a bug which is thanks to a report by Don Albert. The problem is that whenever salloc exits with a child process in stopped state (suspended or stopped on terminal input/output), a zombie process is generated, since this case is not caught by the code evaluating the child status. This patch adds the missing case. It uses SIGKILL, which is the only signal that changes the state of a stopped process. It was decided not to try and re-awken the process using SIGCONT, since (a) this happens during session clean-up and (b) if the condition is due to SIGTTIN, the process immediately becomes stopped again. Patch from Gerrit Renker, CSCS.
