CENTER ANNOUNCEMENTS

TRANSITION TO SLURM ON RHEA AND DTNS
The job scheduler for Rhea and the Data Transfer Nodes was changed to Slurm during yesterday’s outage. For information on using Slurm at OLCF, see the Running Jobs section of the Rhea User Guide.

MEETINGS & WORKSHOPS

AUGUST OLCF USER CONFERENCE CALL (AUG 28)
Thanks for joining us for the August OLCF User Conference Call, which included a discussion of the transition to Slurm as the scheduler for Rhea and the Data Transfer Nodes. If you missed the call, or if you attended and would like to review the material, the slides and a link to the video will be uploaded to the event
page.

INTRODUCTION TO AMD GPU PROGRAMMING WITH HIP WEBINAR (SEP 6)
AMD Research will be presenting a webinar titled, “Introduction to AMD GPU programming with HIP” on September 6th from 1:00 PM to 3:00 PM ET. HIP is a C++ runtime API that allows developers to write portable code to run on AMD and NVIDIA GPUs. It is an interface that uses the underlying Radeon Open Compute (ROCm) or CUDA platform that is installed on a system. The API is similar to CUDA so porting existing codes from CUDA to HIP should be fairly straightforward in most cases. For more information, or to register, please visit the event page.

UPCOMING SCHEDULED OUTAGES

HPSS will be unavailable from 8:00 AM until midnight on Tuesday, September 10.
