ExaMPI25 - Workshop on Exascale MPI 2025
Sunday November 16, full day
Held in conjunction with SC25:
The International Conference for High Performance Computing, Networking,
Storage and Analysis, November 16-21, 2025, St. Louis, Missouri, USA
The MPI standard and its implementations have proven to be both scalable and highly capable of capitalizing on novel software and hardware technologies.
However, trends towards increasingly heterogeneous compute nodes, containerization, networks with powerful offloading capabilities,
alternative programming models, and non-traditional workloads present new challenges and opportunities for innovation. The aim of this workshop is to
bring together developers and researchers to present and discuss algorithms, protocols, operations, and concepts in message passing programming models that address these challenges and opportunities, with a focus on MPI in particular.
Submissions targeting any relevant topic are welcomed. Topics of interest include (but are not limited to):
· MPI for AI applications.
· Design and development of scalable message passing collective operations.
· Innovative algorithms for scheduling/routing to avoid network congestion.
· One-sided communication models and RDMA-based MPI.
· Support for heterogeneous compute devices and heterogeneous memory systems.
· MPI multi-threading and threading requirements from OSes.
· Interoperability of message passing and other programming models,
such as PGAS.
· Communication and architecture topology mapping interfaces and algorithms.
· Integration of task-parallel models into message passing models.
· Fault tolerance in MPI.
· Utilization of `smart' or programmable offloading technologies.
· MPI I/O.
