Dear Dewight,

The Xeon Phis can be used for both shared-memory multiprocessing and 
distributed-memory multiprocessing (through MPI) but in either case the 
software will need to be recompiled to support the Xenon Phi processors. 
The Texas Advanced Computing Center uses Xenon Phi cards in their 
Stampede cluster. Their user guide for stampede ( 
https://portal.xsede.org/tacc-stampede ) has a description of the 
different application scenarios for the Phi coprocessors as well as a 
guide to the relevant software flags for compilation.
