NHR PerfLab Seminar: MPI State of the Union (June 30, hybrid)

Speaker: Prof. Dr. Martin Schulz, Technische Universität München (TUM)

Date and time: Tuesday, June 30, 2026, at 2:00 p.m. CEST

Abstract:

The Message Passing Interface (MPI) remains the de facto programming model for scalable distributed-memory high-performance computing. This talk provides an overview of the current state of the art in MPI, with a focus on the additions to the standard in MPI-4.x and MPI‑5 and their impact on performance, portability, and programmability on modern heterogeneous systems. I will highlight key advances such as partitioned communication, persistent collective operations, MPI sessions, improved tools interfaces, and deeper integration with accelerators and memory hierarchies. Building on these developments, the talk will then cover ongoing work within the MPI Forum that is shaping the next generation of the standard, which will likely be MPI 6.0. Topics include further support for GPU-native communication, fault tolerance and resilience, and malleability and support for dynamic resource management.

Short Bio:

Martin Schulz is a Full Professor and Chair for Computer Architecture and Parallel Systems at the Technische Universität München (TUM), which he joined in 2017, as well as a member of the board of directors at the Leibniz Supercomputing Centre. Prior to that, he held positions at the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory (LLNL) and Cornell University. He earned his Doctorate in Computer Science in 2001 from TUM and a Master of Science in Computer Science from UIUC.

Martin’s research interests include parallel and distributed architectures and applications; performance monitoring, modeling and analysis; memory system optimization; parallel programming paradigms; tool support for parallel programming; power-aware parallel computing; and fault tolerance at the application and system level, as well as quantum computing and quantum computing architectures and programming, with a special focus on HPC and QC integration.

Martin has published over 250 peer-reviewed papers and currently serves as the chair of the MPI Forum, the standardization body for the Message Passing Interface, one of the dominating standard in High-Performance Computing. He was a recipient of the IEEE/ACM Gordon Bell Award in 2006 and an R&D 100 award in 2011. He served on many conference and workshop organizing and program committees, including as program chair for ISC 2021, PC area chair at IPDPS 2021 and general chair of EuroMPI 2021.
