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…
A More Scalable Sparse Dynamic Data Exchange
Andrew Geyko, Gerald Collom, Derek Schafer +2
Parallel architectures are continually increasing in performance and scale, while underlying algorithmic infrastructure often fail to take full advantage of available compute power…
Collective-Optimized FFTs
Evelyn Namugwanya, Amanda Bienz, Derek Schafer +1
This paper measures the impact of the various alltoallv methods. Results are analyzed within Beatnik, a Z-model solver that is bottlenecked by HeFFTe and representative of applicat…
