Linux clusters#

Operating system packages#

The following software should be installed by the system administrator:

  • C, C++ compilers

  • MPI

Danger

The configure will look for mpicc and mpicxx for building packages requiring MPI. Do not set CC=mpicc or CXX=mpicxx as this can lead to packages assuming you are using an Intel compiler. For example, the Python configure detects use of an Intel compiler by comparing $CC against the pattern *icc*.

Configure#

We assume that Python was not built with the same compiler suite as MPI. The --enable-python option will also trigger building all of the Python modules needed. We use 8 threads when building.

If Python was built with the same compilers used to build MPI, then then you do not need the --enable-python option.
