mpi

An mpi library written in C++ that is capable of running simple C based MPI programs

Example programs are provided and built using the makefile. Refer to makefile for building with your own C program.

The only supported datatypes are MPI_CHAR and MPI_INT.

The MPI_Reduce method only supports MPI_INT datatypes, and the only built-in aggregate function is MPI_SUM. However, custom aggregate functions can be defined using MPI_Op_create.

All methods are based upon the MPICH implementation.

Available MPI methods:

  • MPI_Init

  • MPI_Comm_size

  • MPI_Comm_rank

  • MPI_Finalize

  • MPI_Barrier

  • MPI_Send

  • MPI_Ssend

  • MPI_Recv

  • MPIWtime

  • MPI_Gather

  • MPI_Bcast

  • MPI_Comm_dup

  • MPI_Isend

  • MPI_Irecv

  • MPI_Test

  • MPI_Wait

  • MPI_Reduce

  • MPI_Op_create
