6.1 Compiling C Programs

In order to analyze the performance of your sequential C program, you'll first need to recompile it using one of the PPW compiler wrapper scripts. Simply use the wrapper scripts in place of your normal C compiler (eg, in place of gcc).

For sequential C programs, you have two options:

For more information on the compiler wrapper commands, please see ppwcc, or ppwupcc if you are using a UPC compiler installation. 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.
