optimized-base

A set of base images optimised for specific HPC architectures

  • Based on RHEL UBI 8
  • Spack-installed libraries
  • Optimized compiler flags for machine micro-architecture
  • Includes a compatible MPI

Building an image

See dists/ for available distributions. Use the makefile to build a container. To build cts1-broadwell e.g.

make cts1-broadwell

Configuring the build Makefile

The makefile will try to select sensible defaults, however those can be configured using environment variables on the commandline or modifying the Makefile. See the top of the Makefile for available options. e.g.

make \
  REPO_ADDR=mydockerregistry.com \
  HTTP_PROXY=http://proxy:80/ \
  HTTPS_PROXY=http://proxy:80/ \
  CONTAINER_RT=docker \
  cts1-broadwell

TODO

  • Narrowly define compiler toolchain. Currenlty uses UBI 8 default (gcc 8.3.1)
  • Move back to a mainline spack commit once some fixes make it to upstream
