SUMMARY:HPC Container Runtimes Have Minimal or No Performance Impact
DESCRIPTION:Workshop\n\nHPC Container Runtimes Have Minimal or No Performa
 nce Impact\n\nTorrez, Randles, Priedhorsky\n\nHPC centers are facing incre
 asing demand for greater software flexibility to support faster and more d
 iverse innovation in computational scientific work. Containers, which use 
 Linux kernel features to allow a user to substitute their own software sta
 ck for that installed on the host, are an increasingly popular method to p
 rovide this flexibility. Because standard container technologies such as D
 ocker are unsuitable for HPC, three HPC-specific technologies have emerged
 : Charliecloud, Shifter, and Singularity.\n\nA common concern is that cont
 ainers may introduce performance overhead. To our knowledge, no comprehens
 ive, rigorous, HPC-focused assessment of container performance has previou
 sly been performed. Our present experiment compares the performance of all
  three HPC container implementations and bare metal on multiple dimensions
  using industry-standard benchmarks (SysBench, STREAM, and HPCG).\n\nWe fo
 und no meaningful performance differences between the four environments, w
 ith the possible exception of modest variation in memory usage.\n\nThese r
 esults suggest that HPC users should feel free to containerize their appli
 cations without concern about performance degradation, regardless of the c
 ontainer technology used.  It is an encouraging development towards greate
 r adoption of user-defined software stacks to increase the flexibility of 
 HPC systems.\n\nTag: Workshop Reg Pass, Containers, HPC\n\nRegistration Ca
