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.

The next maintenance session will be on Tuesday 2nd August from 09:00 until 17:00. There will be no access to the system during this period.

RCAC Meeting

The project submission deadline for the next RCAC meeting is 30th June 2016. Please note that the RCAC meetings are held once per month. 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:

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.
