Finally, mpi4py is installed, being told about this new MPI compiler. \n\nAdditionally, because building MPI from source takes quite some time (10+ minutes), the installation is cached between each build. This means the MPI installation only has to be built once, and is reused the rest of the time, which saves time.\n\nSee [`.travis.yml`](.travis.yml) for the how to do this!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbsamseth%2Fmpi4py-travis","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbsamseth%2Fmpi4py-travis","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbsamseth%2Fmpi4py-travis/lists"}
