Hm, so I am not sure how to approach this. First of all, the test case works for me. I used up to 80 clients, and for both optimized and non-optimized compilation. I ran the tests with trunk (not with 1.4 series, but the communicator code is identical in both cases). Clearly, the patch from Ralph

I'm wondering if we can't make this simpler. What launch environment are you operating under? I know you said you can't use mpiexec, but I'm wondering if we could add support for your environment to mpiexec so you could. On Jul 18, 2010, at 4:09 PM, Philippe wrote: > Ralph, > > thanks for
