Hi, I am completely new to MPI and am having trouble running a job between
two cpus.
The same thing happens no matter what MPI job I try to run, but here is a
simple 'hello world' style program I am trying to run.
#include
#include
int main(int argc, char **argv)

int *buf, i, rank, nints,
Did you use the waitall on the sender or the receiver side? I noticed you
didn't have the request variable at the receiver side that is needed in the
waitall.

Can you send a more accurate code snipit, and/or the code that you are using to
check whether the data is right/wrong?
I ask because I'm a little sus
Hi,
I have used mpi_waitall() to do it.
The data can be received but the contents are wrong.
Any help is appreciated.

I am out of the office until 11/01/2010.
I will be out of the office on vacation the last week of Oct. Back Nov 1.
I will not see any email.

It doesn't look like you have completed the request that came back from Irecv.
You need to TEST or WAIT on requests before they are actually completed (e.g.,
in the case of a receive, the data won't be guaranteed to be in the target
buffer until TEST/WAIT indicates that the request has complete
Hi,
I am using open MPI to transfer data between nodes.
But the received data is not what the data sender sends out .
I have tried C and C++ binding .
data sender:double* sendArray = new double[sendResultVec.size()];
for (int ii =0 ; ii < sendResultVec.size() ; ii++) {

Well that stinks. I'll take care of it - sorry about that. Guess a patch didn't
come across at some point.

MPI won't do this - if a node dies, the entire MPI job is terminated.
Take a look at OpenRCM, a subproject of Open MPI:

This is designed to do what you describe as we have a similar (open source)
project underway at Cisco. If I were writing your system, I
Hello,
There was a bug in the use of hostfiles when a username is supplied which
has been fixed in OpenMPI v1.4.2.
I have just installed the v1.5 and the bug seems to come out again : only
the first username provided in the machinefile is taken into account.
See mails below for the history.

Ray,
Looking back at your original message, you say that it works if you use the
Myricom supplied mpirun from the Myrinet roll. I wonder if this is a mismatch
between libraries on the compute nodes.
What do you get if you use your OMPI's mpirun with:
$ mpirun -n 1 -H ldd $PWD/
I am wondering

Just to let you know -- our main Windows developer is out for a little bit.
He'll reply when he returns, but until he does, there's really no one else who
can answer your question. Sorry! :-\
