Installation tips

Modular MPC

MPC can also be installed directly using the configure script (see ./configure --help) in this later case loading and installing dependencies is to be done manually.

MPC can build with the following REQUIRED dependencies:

  • OpenPA (spack install openpa or from source)

  • HWLOC 1.11.x (spack install hwloc or using source)

  • A launcher:

    • Hydra (spack install hydra or with the sources)

    • PMI (requires libpmi.so --with-slurm / --with-pmi1)

    • PMIx (requires libpmix.so --with-pmix)

It is possible to choose between the following “modules” with --enable/disable-X:

  • lowcomm: the base networking engine for MPC can be manipulated using the mpc_lowcomm.h header

  • threads: user-level thread support (provides posix thread interface pthread.h, semaphore.h, ..)

  • openmp: requires threads provides OpenMP support (GOMP and Intel ABIs)

  • mpi: requires lowcomm provides the MPI 3.1 interface

  • fortran: requires mpi provides the fortran 77,90,08 bindings for MPC

  • mpiio: requires mpi provides the MPI IO interface (both Fortran and C)

For example, a lowcomm only version of MPC can be compiled with --disable-mpi --disable-threads. The configure (or the mpc_status command) should provide information relative to the enabled components.

Note

when the configure succeeds once a reconfigure script is provided for convenience it can be used to pass new options to the configure. You may have to pass --disable-prefix-check to acknowledge that you may be reinstalling MPC in a non-empty prefix (at your own risks).
