We partnered with NVIDIA last week to host the largest virtual GPU Hackathon yet. The 13 participating teams made significant progress in porting and optimizing a wide variety of applications to run on the ALCF’s ThetaGPU system.

In the latest episode of Intel’s Code Together podcast, ALCF’s Kevin Harms and Codeplay Software’s Ruymán Reyes Castro discuss the collaboration with NERSC to enhance the LLVM-based DPC++ open source compiler, the key role of open communities in furthering innovation, fostering a strong ecosystem around SYCL and DPC++, and more.

IWOCL & SYCLcon 2021, which will include the year's first oneAPI Developer Summit, will take place next week (April 26-29). The annual event is designed to share best practices and to advance the use of OpenCL and the SYCL standard for C++ programming of heterogeneous platforms. ALCF staff will be contributing to multiple activities, including the "Layers for OpenCL" tutorial led by Brice Videau on Tuesday, April 27.

In celebration of Earth Day, we take a look at one of the projects leveraging ALCF resources to enhance climate modeling capabilities. With help from ALCF supercomputers, multiple DOE national laboratories are developing the Energy Exascale Earth System Model (E3SM) to improve our ability to predict the effects of extreme climate conditions on energy production, infrastructure, agriculture and other important economic sectors.

In a new piece in the CERN Courier, physicists Thomas Blum, Luchang Jin, and Christoph Lehner discuss the ongoing efforts to shed light on the anomalous magnetic moment of the muon. The authors were part of a team that used ALCF’s Mira supercomputer to calculate the first-ever result for the hadronic light-by-light scattering contribution to the muon’s magnetic moment, controlling for all errors. "The calculation was not easy: it took four years and a billion core-hours on the Mira supercomputer.”

As part of Argonne National Laboratory's Science Careers in Search of Women (SCSW) event today, ALCF’s Jini Ramprakash and Joe Insley hosted the participating high school students for a virtual tour of the ALCF data center and visualization lab. The annual event provides high school students with the unique experience to explore STEM careers through interaction with Argonne’s world-class women scientists and engineers.

At the Exascale Computing Project (ECP) Annual Meeting this week, researchers from DOE, academia and industry will convene to share supercomputing advances and innovations that are shaping the nation’s exascale ecosystem. As part of the meeting, ALCF researchers will provide the ECP community with updates on Argonne’s upcoming Aurora exascale supercomputer, including the latest public information on hardware and software and progress in preparing scientific applications for the system.

ALCF’s Romit Maulik, Bethany Lusch, and Prasanna Balaprakash recently published "Reduced-order modeling of advection-dominated systems with recurrent neural networks and convolutional autoencoders” in Physics of Fluids. Their paper was selected as an Editor’s Pick.

Check out the 2020 ALCF Science Report to learn how the facility and its user community are advancing the forefront of high-performance computing for science. The report includes updates on facility's initiatives and a collection of highlights on notable results produced by ALCF users.
