SUMMARY:Multirate: A Flexible MPI Benchmark for Fast Assessment of Multith
 readed Communication Performance
DESCRIPTION:Workshop\n\nMultirate: A Flexible MPI Benchmark for Fast Asses
 sment of Multithreaded Communication Performance\n\nPatinyasakdikul, Luo, 
 Eberius, Bosilca\n\nAs the modern hardware landscape continues to drastica
 lly change, the degree of parallelism required to maintain a high occupanc
 y of resources has substantially increased. These hardware changes have hi
 ghlighted the limitations of the traditional method of using one process p
 er processing unit, which indicates that a more flexible programming parad
 igm is necessary. In the context of the message passing paradigm, MPI need
 s a significant improvement in threaded performance in order to fully util
 ize all hardware capabilities. However, for developers to know what needs 
 to be improved, and for users to know what performance to expect, benchmar
 ks are needed to quickly assess the capabilities and performance of MPI im
 plementations. This paper introduces a new communication benchmark designe
 d to replicate typical application communication patterns and assess their
  performance with a varied amount of resources. We evaluate three MPI impl
 ementations with our benchmark suite and assess their strengths and weakne
 sses.\n\nTag: Workshop Reg Pass, Exascale, MPI, Networks, Parallel Program
