mpiLibConf - Location of MPI implementation

Syntax

[primaryLib, extras] = mpiLibConf

Arguments

Description

[primaryLib, extras] = mpiLibConf returns the MPI implementation library to be used by a parallel job. primaryLib is the name of the shared library file containing the MPI entry points. extras is a cell array of other library names required by the MPI library.

To supply an alternative MPI implementation, create an M-file called mpiLibConf, and place it on the MATLAB^® path. The recommended location is matlabroot/toolbox/distcomp/user.

Remarks

Under all circumstances, the MPI library must support all MPI-1 functions. Additionally, the MPI library must support null arguments to MPI_Init as defined in section 4.2 of the MPI-2 standard. The library must also use an mpi.h header file that is fully compatible with MPICH2.

When used with the MathWorks^® job manager, the MPI library must support the following additional MPI-2 functions:

• MPI_Open_port

• MPI_Comm_accept

• MPI_Comm_connect
