CENTER ANNOUNCEMENTS

USER ASSISTANCE CENTER SCHEDULE
The OLCF User Assistance Center will be closed on Monday, September 2 due to an ORNL-observed holiday. The normal user assistance schedule will resume on Tuesday, September 3. NOTE: The ORNL Computer Operations staff will still be available for limited troubleshooting 24 hours a day.

TRANSITION TO SLURM ON RHEA AND DTNS
Rhea and the Data Transfer Nodes will transition to using Slurm for job scheduling on September 3, 2019. To help ensure a smooth transition, we have made 192 Rhea nodes and 2 DTNs available for your testing purposes. Slurm is available from the login nodes of both systems, and we encourage you to try it out before the transition on September 3. For more 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)
The August OLCF User Conference Call will be held at noon (Eastern Time) today (Aug 28). The call will include a discussion of the Slurm scheduler led by OLCF’s Chris Fuson. Details of the call, including information on how to join, can be found on 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.
