SUMMARY:Containerization on Petascale HPC Clusters
DESCRIPTION:State of the Practice Talk\n\nContainerization on Petascale HP
 C Clusters\n\nRuhela, Vaughn, Harrell, Zynda, Fonner...\n\nContainerizatio
 n technologies provide a mechanism to encapsulate applications and many of
  their dependencies, facilitating software portability and reproducibility
  on HPC systems. In order to access many of the architectural features tha
 t enable HPC system performance, however, compatibility between certain co
 mponents of the container and host are required, resulting in a trade-off 
 between portability and performance. In this work, we discuss our early ex
 periences running three state-of-the-art containerization technologies on 
 the petascale Frontera system. We present how we build the containers to e
 nsure performance and security and their performance at scale.  We ran mic
 robenchmarks at a scale of 4,096 nodes and demonstrate the near-native per
 formance and minimal memory overheads by the containerized environments at
  70,000 processes on 1,296 nodes with scientific application MILC, a quant
 um chromodynamics code.\n\nTag: Best Practices, Containers, System Managem
