Sorry about that, I had misinterpreted your original post as being the

Yeah bummers, but something tells me it might not be OpenMPI's fault. Here's
why:
1- The tech that takes care of these machines told me that he gets RTC errors
on bootup (the cpu borads are apprantly "out of sync" since the clocks aren't
set correctly).
2- There is also a possibility that the p

Hello everyone,
I am having a hard time getting OpenMPI (1.1.2) to run in a
heterogeneous environment. In short, here is my command line:
orterun --prefix ~/openmpi_x86_64/ -hostfile head -np 2 mandelbrot-mpi_x86_64
1 400 400 0 : --prefix ~/openmpi_i686/ -hostfile nodes -np `wc -l
igure: error: Could not find MPI library
Anyone can help me with this one...?
Note that LAM-MPI is also installed on these systems...
