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.

 

We will monitor the queue, if we do find that there is a significant backlog of jobs , we may return to a capped mode with full capacity as needed.

 

As there will only be 4601 nodes available on the system any job requesting more nodes than this will be pending until we schedule a session with all nodes available.

 

If you are planning to run jobs requesting more than 2048 nodes, please can you contact us so that we can discuss the priority of them so that they can schedule them to maximise system utilisation.

 

We will review the system usage over the next month without power capping and decide in consultation with the RCAC whether to continue with this mode of operation.

 

KSL Workshop Series: Boost your Efficiency when Dealing with Multiple Jobs  on  Shaheen II

Sunday, June 5 10:30 – 12:30 p.m.
SeaView room, Level 3, University Library

In this talk, we will present a set of tools to increase your productivity when dealing with a large number of jobs simultaneously.  A large part of  the time will be dedicated to hands on experiments.  No specific knowledge required.  Bring your own laptop and code!

Seats are limited. Please register your interest at: https://www.surveymonkey.com/r/LYQ3V53

    •    10:30 a.m. - Boost your efficiency when dealing with multiple jobs on Shaheen II
    •    11:00 a.m. - Interactive Exercise on Cray XC40 supercomputer Shaheen II
    •    11:30 a.m. - Q&A with KSL team (bring all your HPC questions).
