SUMMARY:Evaluation and Benchmarking of Singularity MPI Containers on EU Re
 search e-Infrastructure
DESCRIPTION:Workshop\n\nEvaluation and Benchmarking of Singularity MPI Con
 tainers on EU Research e-Infrastructure\n\nSande Veiga, Simon, Azab, Ferna
 ndez, Muscianisi...\n\nLinux Containers with the build-once run-anywhere p
 rinciple have gained huge attention in the research community where portab
 ility and reproducibility are key concerns. Unlike virtual machines (VMs),
  containers run the underlying host OS kernel. The container filesystem ca
 n include all necessary non-default prerequisites to run the container app
 lication at unaltered performance. For this reason, containers are popular
  in HPC for use with parallel/MPI applications. Some use cases include als
 o abstraction layers, e.g. MPI applications require matching of MPI versio
 n between the host and the container, and/or GPU applications require the 
 underlying GPU drivers to be installed within the container filesystem. In
  short, containers can only abstract what is above the OS kernel, not belo
 w. Consequently, portability is not completely granted. \n\nThis paper pre
 sents the experience of PRACE (Partnership for Advanced Computer in Europe
 ) in supporting Singularity containers on HPC clusters and provides notes 
 about possible approaches for deploying MPI applications using different u
 se cases. \nPerformance comparison between bare metal and container execut
 ions are also provided, showing a negligible overhead in the container exe
 cution.\n\nTag: Workshop Reg Pass, Containers, HPC\n\nRegistration Categor
