I have openmpi via the distribution package: openmpi-1.4.3-7.fc14.i686 When attempting to make mpicc use another compiler as follows:
mpicc -cc=icc ... I get gcc: unrecognized option '-cc=icc' /tmp/ccHd339C.o: In function `main': It looks like it's just passing this as option to gcc instead of using the supplied compiler. -- Uday
