4.1 Compiling SHMEM Programs

In order to analyze the performance of your SHMEM program, you'll first need to recompile it using a PPW compiler wrapper script. Instead of compiling with cc or gcc, use ppwshmemcc instead.

For more information on the ppwshmemcc command, please see ppwshmemcc. If you experience very high overhead (ie, much longer execution times) while running your program under PPW, see Managing Overhead for tips on how to reduce overhead.
