3.1 Enabling MPI Support

Parallel execution on multiple processors or cores is supported by Angora, provided that the MPI (Message Passing Interface) libraries are installed on your system (e.g., OpenMPI or MPICH2 or other). A precompiled binary version of Angora based on the OpenMPI implementation is available on the Angora website.

If you are compiling Angora from source, you’ll have to enable the MPI feature at compile time. This feature is disabled by default. You can enable MPI functionality in Angora by adding the option ‘--with-mpi’ to the configure command line:

 
johndoe@mysystem:~/angora-package-version$ ./configure --with-mpi

For more information on launching Angora simulations on multiple processors or cores using MPI, see section Parallel Execution.
