Building an MPI Application

To build an MPI application for the host node and the Intel® Xeon Phi™ coprocessor, follow these steps:

1. Establish the environment settings for the compiler and for the Intel® MPI Library:

   $ . <install-dir>/composerxe/bin/compilervars.sh intel64
   $ . <install-dir>/impi/intel64/bin/mpivars.sh		

2. Build your application for Intel® Xeon Phi™ coprocessor:

   $ mpiicc -mmic myprog.c -o myprog.mic	
   	

3. Build your application for Intel® 64 architecture:

   $ mpiicc myprog.c -o myprog
