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.

KSL Workshop Series: Introduction to Parallel Computing on Shaheen II

Thursday, 14th July from 10:00 am - 12:30 pm

SeaView room, Level 3, University Library

The aim of this course is to give new users of Shaheen II an introductory overview of the system and its usage, and to help them make efficient use of their allocated resources.

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.

Maintenance Session Tuesday 31st May

The next maintenance session will be on Tuesday 31st May from 09:00 until 17:00. There will be no access to the system during this period.
