MPI issues with Xcode5

Question

I am trying to compile a simple Hello World program in Xcode5 using MPI. But Xcode doesn't recognize the header:

#include <mpi.h>

Searching online, it seems that Xcode5 doesn't work well with an MPI compiler.

Is there a way to make them work together? If so, can you point me into the right direction? If not, how do you compile MPI on your Mac?

Answer 1

I know that it is possible to compile MPI with Xcode and that I've done it before, but it's been a long time since I tried so I won't be able to answer that part of your question.

However, I think most people that are writing MPI programs don't bother with an IDE (like Xcode, Eclipse, etc.) because it's usually a bit of a pain to take advantage of most of the features of IDEs when you're primarily using a non-standard library as MPI is. Most of us just use the command line and call mpicc and mpiexec directly.

However, that being said, I know that Eclipse does have a Parallel Tools Platform that does some magic with MPI and other parallel programming libraries. There have been quite a few questions about it on this site that you can browse around for and you can check out their website for lots of information as well.
