Meetings & Workshops
August OLCF User Conference Call
Thanks for joining us for the August OLCF User Conference Call, which featured a discussion of NVIDIA RAPIDS Updates at OLCF led by OLCF’s Benjamín Hernández. Links for the slide deck and call video are available in the OLCF Training Archive and on the event page at https://www.olcf.ornl.gov/calendar/userconcall-aug2021.
HOLA Hands-on with Summit (Sep 13; Registration Ends Sep 2)
The Oak Ridge Leadership Computing Facility (OLCF) and the Hispanic and Latino Organization for Leadership and Awareness (HOLA) will host a hands-on training with the Summit supercomputer from 1:00 PM until 4:00 PM on Monday, September 13. Participants will learn about the Summit architecture, learn how research teams write programs for and run workloads on Summit, and get to work through fun challenge problems on their own on the Ascent training system (a single-cabinet version of Summit). The training is focused for the beginner level of HPC and students are welcome. You must register by Sept. 2. Participation is limited to 100 people. For more information or to register, visit https://www.olcf.ornl.gov/calendar/hola-hands-on-summit/.
2021 CUDA Training Series (Sep 14 & Oct 13)
NVIDIA will continue their CUDA Training Series with the webinars listed below. Each webinar will include a presentation and hands-on exercises. Webinars will be held from 1 PM to 3 PM (Eastern Time). More information about these sessions and recordings of previous sessions can be found at https://www.olcf.ornl.gov/cuda-training-series/.
Facility Testing of E4S via E4S Testsuite, Spack Test, and Buildtest (Sep 14)
The presentation will provide a brief overview of buildtest commands and how to write tests in buildspecs, followed by a demo. The presentation will include an overview of Cori testsuite, which is a repository that contains sanity test for the Cori system including E4S tests using E4S Testsuite. Gitlab is used to help automate execution of tests which are pushed to CDASH for post-processing. The presentation will end with a summary of E4S tests that are run on Cori, as well as current challenges.

HPC Best Practices Webinar (Sep 15)
The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) run a webinar series on Best Practices for HPC Software Developers. The September webinar will be presented by Wolfgang Bangerth and is titled What I Learned from 20 Years of Leading Open Source Projects. The webinar will take place on Wednesday, September 15, 2021 at 2:00 pm ET. The webinar is free and open to the public, but registration is required and is available at https://exascaleproject.zoomgov.com/meeting/register/vJIsd-qprjgpEv1GMg5MlnUUhVIJir2ocas.
Introduction to OpenMP GPU Offloading (Sep 22-23)
On September 22-23 from 1-3:30 PM (ET) the Oak Ridge Leadership Computing Facility (OLCF)
will offer a (virtual) Introduction to OpenMP GPU Offloading. This training is meant for OLCF
users who are already familiar with the basic ideas of GPU programming but who want to learn
about the core GPU offloading capabilities of OpenMP.
During each day of the training, OLCF staff will give a lecture followed by hands-on exercises for
the participants to work through. On day 1, we will give a general overview of the OpenMP
programming model and cover the basics of using OpenMP directives to offload work to GPUs.
On day 2, we will discuss optimization strategies and show how efficient data movement and a
better understanding of the hierarchy of parallelism available can lead to improved
performance. The hands-on exercises will be available in both C and Fortran and will be
designed to work with a variety of compilers. Time will be reserved for users to work through
the examples during the training and a slack channel will be available for questions during and
after each training session.
