Reminder: CISL’s High Performance Computing Division (HPCD) is asking users for their input on GPU-computing training needs as it develops new learning resources for early 2022. In preparation for greater availability of GPU resources on the Casper cluster and the new Derecho system, HPCD asks GPU and non-GPU users of NCAR’s high-performance computing resources to complete this survey by November 30. Results of the survey will directly influence development of a training series focused on the use of GPU technology in Earth system science research.
