Smoky Mountain Conference Data Challenge 2022
This data analytics competition provides an opportunity to tackle scientific data challenges that come from eminent datasets related to ORNL, industry, and academia . These datasets come from scientific simulations and instruments in physical and chemical sciences, electron microscopy, bioinformatics, engineering, materials science, neutron sources, urban development, and other areas, and will have open research questions and tasks for participants to solve. Competitors have till July 7 to solve one of the challenges and write a paper about their approach. Selected solutions to these challenges will be published in the SMC2022 proceedings in a CCIS Springer volume. Career Researchers and Students compete in different categories. Learn more about the SMCDC22 at

Meetings & Workshops

Appentra Codee Training (Apr 26-27)
NERSC will host training on Appentra’s Codee Analyzer (formerly known as Parallelware Analyzer) on Tuesday, April 26 and Wednesday, April 27 from noon until 3:00 PM (EDT) each day. Appentra Codee Analyzer is a programming development tool for C/C++/Fortran parallel codes on multicore CPUs and GPUs using OpenMP and OpenACC. It provides a systematic, more predictable approach that leverages parallel programming best practices, and enables the novice to write codes at the level of experts, including inserting OpenMP/OpenACC directives to offloading to accelerator devices like GPUs. This training is focused on how the Codee tool provides automated code inspection capabilities for assisting OpenMP/OpenACC programming on GPUs. OLCF and ALCF users are invited and NERSC training accounts will be provided if needed. To register, see

April OLCF User Conference Call: myOLCF Self-Service Portal (Apr 27)
The April OLCF User Conference Call will be held from noon until 1:00 PM Eastern Time on Wednesday, April 27. During this call, OLCF’s Leah Huk will provide an overview of myOLCF, including new features such as the ability to monitor user support tickets. For more information, see the event page at

Coding for GPUs Using Standard Fortran
May 13, 1:00-2:00p.m. EDT
CUDA C++, CUDA Fortran, and OpenACC are hugely successful approaches to GPU programming, but wouldn’t it be nice to write an application that can run on GPUs and multicore CPUs out of the box, without any additional APIs? The parallelism features available in ISO C++ and ISO Fortran enable developers to write their codes such that the baseline code is parallel and ready to run on any parallel platform they encounter.

Join us for the second part of a this NVIDIA ISO programming series that will cover how to use standard Fortran to target both the CPU and GPU. Register at

Upcoming Scheduled Outages

  • HPSS will be unavailable from 8:00 AM until noon on Tuesday, April 26.
  • The Marble outage previously scheduled for April 20-21 has been postponed. The updated schedule will be provided in a future Weekly Update.
