Understanding GPU Triggering APIs for MPI+X Communication
Patrick G. Bridges, Anthony Skjellum, Evan D. Suggs +2
GPU-enhanced architectures are now dominant in HPC systems, but message-passing communication involving GPUs with MPI has proven to be both complex and expensive, motivating new ap…
MPI Implementation Profiling for Better Application Performance
Riley Shipley, Garrett Hooten, David Boehme +3
While application profiling has been a mainstay in the HPC community for years, profiling of MPI and other communication middleware has not received the same degree of exploration.…
Implementation-Oblivious Transparent Checkpoint-Restart for MPI
Yao Xu, Leonid Belyaev, Twinkle Jain +3
This work presents experience with traditional use cases of checkpointing on a novel platform. A single codebase (MANA) transparently checkpoints production workloads for major ava…
MPI Advance : Open-Source Message Passing Optimizations
Amanda Bienz, Derek Schafer, Anthony Skjellum
The large variety of production implementations of the message passing interface (MPI) each provide unique and varying underlying algorithms. Each emerging supercomputer supports o…
Checkpoint-Restart Libraries Must Become More Fault Tolerant
Anthony Skjellum, Derek Schafer
Production MPI codes need checkpoint-restart (CPR) support. Clearly, checkpoint-restart libraries must be fault tolerant lest they open up a window of vulnerability for failures wi…
