Hello Siegmar,
this problem is already fixed in the OMPI trunk (r27770), but currently not
moved to the v1.6 branch.
To make it working for the v1.6 branch, just copy the following files from the
trunk to your v1.6 checkout and re-run autogen.sh:
ompi/contrib/vt/vt/config/m4/acinclude.execwrap.m4
Hello all.
I want to learn MPI and I've trying to setting up OMPI for first time on
three nodes. My config above:
Ubuntu server - master node: pruebaborja
2x Ubuntu Desktop - slaves node:
clienteprueba
clientepruebados 4 slots
Im running NFSv4 for sharing /home/mpiuser.
I want to test a plain "Hel
FWIW, I can replicate the behavior with gfortran 4.7.2:
- program runs "fine" with no MPI_Init/MPI_Finalize
- program dumps core when MPI_Init/MPI_Finalize are called (at the "conc = [
xx, yy ]" statement)
I notice that even if I disable Open MPI's memory hooking, the coredump still
occurs.

Try disabling firewalling between your nodes. The easiest way is "sudo service
iptables stop".

Hello,
I have a large fortran code processing data (weather forecast). It runs ok with
smaller dataset, but on larger dataset I get some errors I've never seen before:
node061:05144] [[55141,0],11]->[[55141,0],0] mca_oob_tcp_msg_send_handler:
writev failed: Bad file descriptor (9) [sd = 9]

Getting the same error...
I forgot to say that I must to use Ubuntu and Im compiling with mpicc. My
code is written on C.
Thank for answer.
Im going crazy with this problem. There's not much info about.

If you login to eprueba and try to ping pruebaborja, can you do it? What
network is it using?
Sometimes the problem is that you have multiple ethernet interfaces on the
machines and we pick the wrong one - i.e., one that cannot connect to the other
machine. There are ways to help resolve the pr
Make sure you disable iptables on all the nodes.
Also, check that all your IP interfaces are configured correctly. Do you have
IP interfaces for only real ethernet connections and loopback? Or do you have
other interfaces (e.g., for virtual machines)?
If you have interfaces for virtual machin

It was both intentional and a typo.
Specifically, it really should have bee
There is a significant improvement in non-blocking MPI calls (over
Infiniband) from version 1.4 to version 1.6.
I am comparing two methods to exchange messages between two nodes. The
message size varies from 1 MB to 1 GB.
The first method is sends using MPI_Isend()and receives using MPI_Irecv().

Which version of OMPI are you using?
