Dear Open MPI users
Do you have any suggestions on how to install and use Open MPI in a PC network
running Windows XP?
Thank you in advance
George Tsigaridas
I am new to open MPI
I have a simple program below:
#include
#include
#include "mpi.h"
using namespace std;
void* backID(void* arg)
{
int myid;
MPI_Comm_rank(MPI_COMM_WORLD, &myid);
cout << myid << " create background ID" << endl;
int v;
MPI_Status status;
int m;
int x, y;
int count
have you tried running hostname
$mpirun -np 2 --mca btl openib,self --host node1,node2 hostname
if it hangs, it's not Open MPI problem, check your setup,
especially check your firewall settings and disable it.

Thanks, Jeff.
OK, I've found the offending code and gotten rid of the fork() warning. I'm
still left with this:
[bl302:26556] *** An error occurred in MPI_Cart_create
[bl302:26556] *** on communicator MPI_COMM_WORLD
[bl302:26556] *** MPI_ERR_ARG: invalid argument of some other kind

Hello.
Thanks!

Hi,
I encountered a very very confused problem when running IMB via two
nodes by using IB.
OS: RHEL 5.2
OFED Version: 1.4.1
MPI: OpenMPI 1.3.2 (OFED owned)
I run IMB-MPI1 provided by OFED OpenMPI tests. The command line is
mpirun -np 2 --mca btl openib,self --host node1,node2 IMB-MPI1
After th
Hi Jakob, Thanks for reply.
Please see below.

If you don't use btl_tcp_if_include, Open MPI should use all available
ethernet devices, and *should* (although I haven't tested this
recently) only use devices that are routable to specific peers.
Specifically, if you're on a node with eth0-3, it should use all of
them to connect to anoth
Hi!
The CMS (Cell Messaging Layer) is a function collection, wherewith you can
provide spu with parallel communications. I never user it, just read about
this technology.
I read this fact that, in CMS function environment just the synchronized
communication is allowable, you can't programming the

I'll let the Myricom guys answer further for message passing

- Yes, using processor affinity might help. Add "--mca

helps.
- I *believe* that HP MPI uses processor affinity by default -

I am unable to replicate your problem with the code below -- can you
be more precise about your system details, Open MPI version, etc.?
