Smoky Mountain Conference Data Challenge 2022

You are invited to participate in Oak Ridge National Laboratory’s the Smoky Mountains Data Challenge ( It is comprised of 8 data analytics challenges based on data sets contributed by ORNL, Industries, and Academia. Expert data scientists, as well as students, are called to participate. Registration is open until June 23 (hxxps:// Winners will have an opportunity to publish their solutions and participate in the Smoky Mountains Computational Sciences and Engineering Conference. Please join our kick-off zoom meeting on May 10th at 11:00 a.m. EDT. We will provide an overview of the data analytics challenges and take your questions.

Join the Kick-off zoom meeting on May 10, at 11:00 am EDT

2023 INCITE Call for Proposals
The 2023 Innovative and Novel Computational Impact on Theory and Experiment (INCITE) Call for Proposals is now open and closes June 17 for new proposals (July 22 for renewals).

The INCITE program seeks proposals for high-impact, computationally intensive research campaigns in a broad array of science, engineering, and computer science domains. The program promotes transformational advances in science and technology through large allocations of computer time and supporting resources at the Argonne and Oak Ridge Leadership Computing Facilities operated by the DOE Office of Science. INCITE is open to researchers from all institutions, including academia, industry, and government agencies.

INCITE is also devoting 10% of its allocatable compute time to a new Early Career Track, which aims to encourage the next generation of HPC researchers by focusing on principal investigators who are within 10 years of earning their doctorate degrees (on or after December 31, 2012).

HIP v5.1.0 Available on Summit
HIP v5.1.0 is now available on Summit using the underlying CUDA platform. Loading the `hip-cuda/5.1.0` module requires that CUDA >= v11.4 is loaded first through one of the stand-alone `cuda` modules. This build currently includes the following libraries in addition to HIP: hipBLAS, hipFFT, hipRAND, hipSolver, and hipSparse. If you find issues when using this module, please submit a ticket to to request help.

April OLCF User Conference Call: myOLCF Self-Service Portal
Thanks for joining us for the April OLCF User Conference Call, which included an overview of myOLCF. For links to the slide deck and call video, 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

INCITE Informational Webinars (Jun 3)
To help you prepare your proposal for submission, the INCITE program is offering an instructional webinar on June 3 at 2 PM EDT/1 PM CDT. The 1.5 hour webinar will include a discussion of the Director’s Discretionary Program, which is a way to request early access to port, tune, and scale your code in preparation for an INCITE application. To register, visit

Data Visualization & Analytics Series: Jupyter Workflow at OLCF
July 14, 1:00–3:00p.m. EDT
The OLCF is proud to offer the first event of the Data Visualization and Analytics training series: Jupyter Workflow at OLCF. Jupyter notebooks offer a unique environment for users to analyze and process scientific data. The interactive nature of the web interface allows one to debug, visualize, and share code instantly, without having to handle everything on the command-line. This event will provide an overview of how to access Jupyter at OLCF and how to utilize the interface in an analytics setting, including hands-on examples of how to analyze data generated on OLCF systems, along with a Deep Learning workflow demo run with Jupyter.

The hands-on component of this training is limited to 30 users with moderate security enclave projects (i.e. able to access Summit/Andes), although others are welcome to sign up and attend the presentations. Additionally, hands-on examples will be available after the event for Moderate users to access and work with on their own. For more information or to register, see

How to be Great Mentor Seminar
May 24, 1:00-2:15 pm EDT
Mentoring is vital to developing and retaining a diverse, talented, and enabled workforce. Therefore, the first session of the Exascale Computing Project (ECP)
Workforce Development Seminar series will feature a panel of experienced mentors drawn from High-Performance Computing (HPC) and STEM related careers, who will discuss tips for building the important mentor/mentee relationship and best practices in mentoring. They will share what they have learned from their mentees about developing, networking, and sponsoring the next generation of HPC and STEM professionals. All are welcome to join.
