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…
The Impact of Space-Filling Curves on Data Movement in Parallel Systems
David Walker, Anthony Skjellum
Modern computer systems are characterized by deep memory hierarchies, composed of main memory, multiple layers of cache, and other specialized types of memory. In parallel and dist…
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…
A Survey of Potential MPI Complex Collectives: Large-Scale Mining and Analysis of HPC Applications
Pouya Haghi, Ryan Marshall, Po Hao Chen +2
Offload of MPI collectives to network devices, e.g., NICs and switches, is being implemented as an effective mechanism to improve application performance by reducing inter- and int…
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…
