Hi all,
I'm trying to run a code on 2 machines that has at least 2 network
interfaces in it.
So I have them as described below:
compute01
compute02
ens3
192.168.100.104/24
10.0.0.227/24
ens8
10.0.0.228/24
172.21.1.128/24
ens9
172.21.1.155/24

Issue is. When I execute `mpirun -n 2 -
Hi!
Thank you all for your reply Jeff, Gilles and rhc.
Thank you Jeff and rhc for clarifying to me some of the openmpi's internals.

Hi all.
I've an MPI application in which at one moment one rank receives a slice of
an array from the other nodes.
Thing is that my application hangs there.
One thing I could get from printint out logs are:
(Rank 0) Starts MPI_Recv from source 4
But then it receives:
MPI_Send from 0
MPI_Send from
Not "MPI_Send from 0"..
MPI_Send from 1 to 0
MPI_Send from 7 to 0
And so on..

Hi all,
I've got a code where I MPI_Isend at a time and later I get the result from
MPI_Test flag to see whether it has completed or not.
So the code is like:
MPI_Isend()
... some stuff..
flag = 0;
MPI_Test(req, &flag, &status);
if (flag){
free(buffer);
}
After the free() i'm getting errors
sing around 2GB which I'm guessing it isn't
freeing it.
Is there anything I could try?
Regards,
C.

Hi all,
Sorry no reply.
I just figured out the solution.
The problem was that I had a function that would MPI_Isend a message on
every call to it. Then I'd store its request pointer to a list.
My MPI_Isend snippet:
MPI_Request req;
MPI_Isend(blabla, &req)
task_push(&req);

Hi all,
I'm trying to MPI_Spawn processes with no success.
I'm facing the following error:
=
All nodes which are allocated for this job are already filled.
==
I'm setting the hostname as follows:
MPI_Info_set(minfo, "host", hostname);
I'm already running with `--o
OG: Unreachable in file
dpm/dpm.c at line 433
Other than this the error is always:
--
All nodes which are allocated for this job are already filled.
