Dear all,
As I mentioned, when I mpiruned an application with the parameter "np =
150(or bigger)", the application who used the MPI_Alltoallv function would
carsh. The problem would recur no matter how many nodes we used.
The edition of OpenMPI: 1.4.1 or 1.4.3
The OS: linux redhat 2.6.32
BTW, my
I'm trying to cross-compile.

Don't give it a host argume
I think you've reversed the role of host and target then. "host" is the machine
type you are compiling on, and "target" is the machine you are compiling for.
There used to be a wiki page on cross-compiling OMPI, but I couldn't locate it
this morning - I'm sure it's still there, but it is hard to
--host is the correct option, but the host string "arm" is not valid; it
needs to be a proper triple, something like "x86_64-unknown-linux-gnu".
Either way, ARM was not a supported platform in the 1.4.x release; the
earliest version of Open MPI to support the ARM platform was 1.5.2.

I tried 1.5.2 and 1.5.3.

There's some extra special mojo that needs to be supplied when cross-compiling
Open MPI (e.g., a file that specifies all the ./configure answers for tests
that it can't run in a cross-compiling environment).
The wiki page Ralph was talking about was referring to instructions on how to

Hi:
I'm running openmpi 1.2.8. I'm working on a project where one part
involves communicating an integer, representing the number of data
points I'm keeping track of, to all the processors. The line is simple:
MPI_Allreduce(&np,&geo_N,1,MPI_INT,MPI_MAX,MPI_COMM_WORLD);
where np and geo_N
