Installation tips

Modular MPC

MPC can also be installed directly using CMake (see the -LH option of cmake for the available cache variables), 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 (spack install hwloc or from 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 (or -DMPC_ENABLE_X=ON|OFF when building with CMake directly):

  • 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), disabled with --disable-romio

  • openshmem: requires lowcomm provides the OpenSHMEM interface

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