• Native MPI support (MPICH-based)

  Containers with native MPI performance can be launched by passing the --mpi option to the sarus run command, e.g.:

  Code Block
  language bash theme RDark
  srun -N16 -n16 -C gpu sarus run --mpi <repo name>/<image name>:<image tag> <mpi_application>

  In

  order

  to

  access

  the

  high-speed

  Cray

  Aries

  interconnect,

  the

  container

  application

  must

  be

  dynamically

  linked

  to

  an

  MPI

  implementation

  that

  is

  ABI-compatible

  with

  the

  compute

  node's

  MPI

  on

  Piz

  Daint.

  We

  recommend

  one

  of

  the

  following

  MPI

  implementations:

  • MPICH v3.1.4 (Feburary 2015)
  • MVAPICH2 2.2 (September 2016)
  • Intel MPI Library 2017 Update 1
