RCAC meeting

The project submission deadline for the next RCAC meeting is June 30th. Please note that the RCAC meetings are held once per month. Projects received on or before the submission deadline will be included in the agenda for the subsequent RCAC meeting.The detailed procedures, updated templates and forms are available here: https://www.hpc.kaust.edu.sa/account-applications


Tip of the week: (Reminder) /scratch is the right place to run simulations

Shaheen users should keep in mind that /project space is usually NOT recommended for running jobs. You should be running your jobs on /scratch and, after post processing, you should copy ONLY necessary files to /project. Those of you who are used to running all jobs from /project, it is time to start running your jobs on /scratch. This is a standard practice on supercomputers. Please note this change will not drastically change the way you run your jobs. The idea is to have the directory of your input files on /project, and the job script should automatically move the necessary files to /scratch, run the job, delete temporary files, run analytics/postprocessing, and copy ONLY necessary files to /project. Here is a simple test case that we prepared for demonstartion. Just do the following:

 tar -xf /sw/xc40cle7/openfoam/work_lustre_scratch.tar

 cd work_lustre_scratch/

 cat job.sh

 sbatch job.sh 

Once you run this test case, you might want to take a look at the job script and edit it according to your specific test case. Do not hesitate to contact us if you need help. Reducing data on /project reduces the need for backing up data, which in turn helps all Shaheen users. 

The users should also remeber that any files under /scratch/<username> or /scratch/project/kxxx that have not been acessed in the last 60 days will be deleted automatically without warning and are unrecoverable. Please rememebr to back up any important data to your /project/kxxxx or /home/<username>. We are available for any follow up questions or clarifications (help@hpc.kaust.edu.sa).
