SUMMIT DEFAULT MODULE CHANGES (MAR 12)
New versions of software have been installed on Summit and will be set as default on March 12 unless issues are reported. Users are encouraged to use the new versions and report issues to firstname.lastname@example.org. To view a list of the new versions, visit the Software News page.
SUMMIT KNOWN ISSUES
The Summit User Guide now contains a Known Issues section. This section contains a list of currently open issues (with a workarounds if one is available) as well as issues that have been resolved as a result of system updates.
RHEA UPGRADE TO RHEL 7 (MAR 12)
Rhea’s operating system will be upgraded to Red Hat Enterprise Linux version 7 (RHEL7) during the outage on Tuesday, March 12. After the upgrade, you will need to recompile codes prior to running on the upgraded system. During the upgrade, default modules, including compiler, CUDA, and OpenMPI, will also change. For more information on the upgrade including software defaults, updates to Python runtime management, FreeNX decommission, and the upgrade to Lmod, please see 2019 OLCF System Decommissions and Notable Changes page on the OLCF website.
NOTABLE SYSTEM CHANGES IN 2019
On February 25, 2019, we notified users of several notable system changes coming in 2019. The last day to submit jobs to Titan and Eos will be June 30th. Atlas will be made read-only on August 1 and all data will be permanently deleted on August 15. We strongly encourage users to begin moving data out of that filesystem and onto the newer Alpine filesystem or to some alternate locate as soon as possible. If you have questions about data movement, please contact email@example.com. For more information, please see the 2019 OLCF System Decommissions and Notable Changes page on the OLCF website.
2019 OLCF USER MEETING
The Oak Ridge Leadership Computing Facility (OLCF) is pleased to announce the 2019 OLCF User Meeting will be held May 21-23 at Oak Ridge National Lab in Oak Ridge, TN. The purpose of the annual user meeting is to share selected computational science and engineering achievements emerging from OLCF’s user programs, to enable direct interactions among users, advance OLCF’s relationships with our user community, and highlight computational requirements for the future. Highlights of the meeting include paired talks from OLCF users and application developers, plenary talks, updates from center staff, a poster session, OLCF User Group Executive Board elections, and tours of OLCF. Additionally, OLCF will offer training on the Monday prior to the meeting for those interested. For more information or to register, please visit the event page.
MEETINGS & WORKSHOPS
FEBRUARY OLCF USER CONFERENCE CALL
FEBRUARY OLCF USER CONFERENCE CALL (FEB 27)
Thanks for joining us for our February OLCF User Conference Call, which included a discussion of Advanced On-Node GPU Communication by NVIDIA’s Stephen Abbott. The call video will be uploaded to the OLCF Training Channel on Vimeo (https://vimeo.com/olcf). The slides (and a link to the video) will be uploaded to the event page.
VI-HPS TUNING WORKSHOP (APRIL 9-12)
The Virtual Institute – High Productivity Supercomputing (VI-HPS) is holding a tuning workshop at the Innovative Computing Laboratory (ICL) at the University of Tennessee (UTK) from April 9-12, 2019. The goal of the workshop is to give an overview of the VI-HPS tools suite (Arm tools, PAPI, Paraver, Score-P, etc.) and help participants to analyze and tune their own MPI, OpenMP, and hybrid MPI+OpenMP parallel applications. TACC’s Stampede2 will be the primary platform for the workshop, and course accounts will be provided during the workshop to participants. For more information, or to register, please visit the event page.
QUANTUM COMPUTING USER FORUM (APR 25)
ORNL is hosting a Quantum Computing User Forum on April 25. This meeting will bring together users to discuss common practices in the development of applications and software for quantum computing systems. The one-day meeting will include invited and contributed presentations from leading researchers in the field of quantum computer science, and it will provide a forum in which to discuss the latest scientific applications of quantum computers. An optional training event will be held one day prior to the Forum. For more information, visit the event page.
INTRODUCTION TO SUMMIT WORKSHOP (MAY 20)
The OLCF will host an Introduction to Summit workshop on Monday, May 20, 2019 from 8:00 AM – 5:00 PM. The event will consist of presentations in the morning followed by a hands-on session in the afternoon. The presentations are meant to deliver relevant information about the system (hardware, job launcher, programming environment, etc.), while the hands-on session is intended to demonstrate specific aspects of the Summit system through a set of provided example programs. For more information, or to register, please visit the event page.
UPCOMING SCHEDULED OUTAGES
All systems will be unavailable from 8:00 AM until 8:00 PM on Tuesday, March 12.
