CENTER ANNOUNCEMENTS

ATLAS IS READ-ONLY; ALL DATA REMOVED ON AUG 19
The Atlas filesystem was made read-only on Monday, August 5 and will be decommissioned (with all data permanently removed) on Monday, August 19. Please begin moving data out of that filesystem and onto the newer Alpine filesystem or to some alternate location immediately. If you have questions about data movement, please contact help@olcf.ornl.gov. For more information, please see the 2019 OLCF System Decommissions and Notable Changespage.

ALPINE PURGE POLICY HAS BEEN IMPLEMENTED
The 90-day purge policy for the Alpine GPFS filesystem was enabled on August 6, 2019. Files in Atlas that have not been accessed or modified in the last 90 days are eligible for the purge.

RHEA JOBS SHOULD USE ALPINE
The Alpine filesystem is now mounted on Rhea, and your jobs should use it instead of Atlas. Atlas has been made read-only and will be decommissioned on August 19 (see the announcement above). Jobs targeting Atlas will now fail. Make sure you’re using Alpine, and if you have any questions please contact help@olcf.ornl.gov.

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 will be making a small number of nodes available for your testing purposes on both Rhea and the DTNs beginning August 13th. We encourage you to try out these nodes prior to the transition on September 3, 2019. We will provide additional information on how to access these nodes as well as links to Slurm documentation as we get closer to the transition date.

MEETINGS & WORKSHOPS

JULY OLCF USER CONFERENCE CALL (JUL 31)
Thank you for joining us for the July OLCF User Conference Call, which included a discussion of Popper (a workflow execution engine) by Ivo Jimenez. If you missed the call, or if you attended and would like to review the materials, you can find the presentation on the event page. The call video will be linked from that page when it is available.

2019 PETASCALE COMPUTING INSTITUTE (AUG 19-23)
The Oak Ridge Leadership Computing Facility (OLCF) will host a branch of the 2019 Petascale Computing Institute from August 19-23, 2019. The goal of the institute is to enable computational and data-enabled discovery in all fields of study by teaching the participants to scale their computational codes to leadership-class computing systems. The institute will be broadcast to host sites using full-duplex audio/video connections. Participants will receive training accounts, on-site mentoring, and the ability to ask questions of the presenters orally and via on-line chats. Presentations will be given by staff members of the organizing institutions (ALCF, NCSA, NERSC, OLCF, PSC, SciNet – University of Toronto, and TACC), and the keynote address will be given by Gordon Bell. For more information, or to register, please visit the event page.

OLCF GPU HACKATHON SERIES
OLCF is once again supporting several GPU hackathons. GPU hackathons are 5-day coding events in which teams of developers prepare their own applications(s) to run on GPUs or focus on optimizing their application(s) that currently run on GPUs. Teams should consist of three or more developers who are intimately familiar with (some part of) their application, and they will work alongside two mentors with GPU programming expertise. If you want/need to get your code running (or optimized) on a GPU-accelerated system, these hackathons offer a unique opportunity to set aside 5 days, surround yourself with experts in the field, and push toward your goals. If you are interested in more information, or would like to submit a proposal to one of the upcoming events, please visit the OLCF GPU Hackathons event page.

The OLCF Hackathon (October 21-25 in Knoxville, TN) is the only hackathon still accepting proposals; the deadline to apply is August 16.

UPCOMING SCHEDULED OUTAGES

Summit, Rhea, the Data Transfer Nodes, HPSS, and the Alpine filesystem will be unavailable from 8:00 AM until 4:00 PM on Tuesday, August 13.

HPSS will also be unavailable from 8:00 AM on Tuesday, August 20 until 8:00 AM on Wednesday, August 21.
