Yeah, everything Pavan said. I forgot what --enable-g meant. If you intend to use a debugger (because you're developing an application that uses MPI), you might find --enable-g=dbg useful, but --enable-g is total overkill for users.

--enable-g=dbg adds debug symbols to the MPI library. To debug the applications, you'll need to set CFLAGS=-g or just compile your application with "mpicc -g". -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
