Running watch on squeue
In the KAUST Supercomputing Laboratory Newsletter of 18th May, we requested all Shaheen users to refrain from running watch on squeue. Unfortunately, this instruction went unobserved by some users, placing an unacceptable load on the SLURM scheduler. We have therefore taken measures to prevent usage of the watch command.
Tip of the Week: Check the balance of your allocation
When a project's allocation has expired and/or has an insufficent balance, jobs scripts will not be released to run on Shaheen. Usually, the reason is either AssocMaxJ and/or AssocGrpC, as shown below:
squeue -u $username
JOBID USER ACCOUNT NAME ST REASON START_TIME TIME TIME_LEFT NODES
1234567 user1 kxxxx job1 PD AssocMaxJ N/A 0:00 1-00:00:00 1
1234568 user2 kxxxy job2 PD AssocGrpC N/A 0:00 1-00:00:00 2
Before submitting your jobs, check your project allocation, expiration and balance using the "sb" command. Use “groups” command to find out your projects number.
