CoE HPC News, Apr 25 2023: AC maintenance, new DGX limits
by Yelle, Robert Brian 25 Apr '23

25 Apr '23

HPCC users, First, thanks to all of you who participated in the HPC usage survey, this was greatly appreciated. The results help us to better understand how the cluster is currently being used and what future trainings might be helpful or of interest. AC maintenance Last Saturday night, some compute nodes were shut down due to datacenter temperatures rising to unsafe levels. This resulted in the termination of some jobs. Cooling has since been partly restored, but this was a short term fix and some additional but urgent maintenance is needed which requires a temporary shutdown of the chillers. This will take place starting early tomorrow (Wednesday) morning. To mitigate the heat load, the cluster will run at reduced capacity during the AC maintenance. It is likely that no additional jobs will be accepted during this time until the maintenance has completed, which should be tomorrow afternoon at the earliest. I expect the cluster will be restored to full capacity by late Thursday morning. New GPU limits on DGX systems Due to the continued increase in the number of users of the DGX systems, the demand for GPUs on the DGX systems lately has been at an all time high! The previous GPU limit of 8 is no longer sustainable at present without some additional modifications. Effective immediately, the cumulative GPU limit on the DGX systems has been reduced to 4 until further notice. For those of you who have deadlines coming up, please contact me directly and we’ll try to work something out. Cheers, Rob Yelle HPC Manager

Survey of cluster usage and training interest
by Yelle, Robert Brian 14 Apr '23

14 Apr '23

Cluster users, We are conducting a survey of our users to better understand how the cluster is being used. When you get a chance, please take a few moments to briefly answer the questions below, and reply directly to me and NOT to the list. Your feedback would be greatly appreciated. 1) How would you describe your cluster usage? a) primarily CPU based b) primarily GPU based c) mix of CPU and GPU 2. What application(s) do you run on the cluster (e.g. Matlab, Ansys, Star-CCM+, VASP, custom, etc.)? 3. What programming language(s) do you use or program in (e.g. Python, C, Fortran, R, etc.)? 4. What libraries, platforms and APIs do you primarily use on the cluster? (e.g. MPI, MKL, BLAS, LAPACK, CUDA, list your key Python or R packages, etc.). Also, Nvidia will offer a series of trainings in the near future on using GPUs on DGX systems. Please answer the following if you are interested in these trainings: 5. Are you interested in migrating from CPU based code to GPU? 6. Are you interested in an introductory workshop on GPU computing? 7. Are you interested in a workshop on accelerating your Python GPU code? 8. Are you interested in a workshop on profiling your GPU code? Thanks! Rob Yelle HPC Manager
