The Message Passing Interface (MPI) is an industry standard way for the parts of a parallel program to communicate. Since its inception in the 1990s, the MPI standard has evolved through several major revisions. Recently the cray-mpich/9.0.x module(s) have been made available on the Frontier system, which add support for the MPI-4.0 standard. This presentation will discuss the important new features in HPE Cray MPI that users and developers on Frontier might want to use. For example, there are now routines for persistent collectives, and large-count versions of routines that allow specifying more than two billion items in a single call.

OLCF, in partnership with AMD, HPE, and others, invites research teams to participate in a competitive hackathon on Frontier, the world’s most powerful supercomputer. Participants will work to advance fundamental scientific discovery by exploring strategies to optimize performance, scalability, and data processing, as well as developing innovative methods to accelerate high-performance computing workflows and enhance computational efficiency. Selected teams will collaborate with leading experts to push the boundaries of what is possible on exascale systems. Proposals are due by March 4.

The Quantum Computing User Forum brings together both users of the Quantum Computing User Program (QCUP) and other interested parties in order to discuss common practices in the development of applications, software, and simulations for quantum computing devices and systems. Hosted by the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory, the Forum is scheduled for July 20-24th, 2026.
