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.

Projects received on or before this deadline will be included in the agenda for the next RCAC meeting, scheduled to be held in July 2016. The detailed procedure and the forms are available here:

KAUST Supercomputing Laboratory Newsletter 1st June

Power Capping

As you are aware the system was previously running with a power cap of 2200KW with occasional sessions without power capping but with a reduced number of nodes. 

 

With the approval of the RCAC is has been decided that we are going to trial an extended run with power capping off, this should mean that code may run faster and will also allow us to prepare a number of projects code to run at scale without capping.

Running watch on squeue

Some users are running a watch on squeue to monitor their jobs.

Please refrain from doing this as it places an increased load on the job scheduler.

If you need notice when a job is starting you can ask Slurm to do this within your job submission file, as follows:

Shaheen II power uncapped

Shaheen II power will be uncapped this weekend (Thursday 5:00 PM until Sunday 8:00 AM). Around 4,000 nodes will be available. The remaining 2,000 nodes will be drained and not available. This is to allow performance tuning and code execution without power restrictions on compute nodes. This session is open to all Shaheen II users.
