[OMPI users] OPENMPI_ORTE_LOG_ERROR
Hi, I'm trying to run my mpi program using open mpi 1.7 rc5 on 4 machines using the command: mpirun -np4 -hostfile file a.out but i get the following message errors: ORTE_ERROR_LOG: A message is attempting to be sent to a process whose contact information is unknown in file ../../../../../ompi/orte/mca/rml/oob/rml_oob_send.c attempted to send to [[21341,0],2]: tag 15 ORTE_ERROR_LOG: A message is attempting to be sent to a process whose contact information is unknown in file ../../../../ompi/orte/mca/grpcomm/base/grpcomm_base_xcast.c The file etc/hosts is composed by ipaddress hostname, I have exchange ssh keys among the machines and ssh login works without requiring authentication password. Surprisingly if I try to run my program with at most 2 hosts, and so the file hosts contains only two hosts, it works but if i try to run my program with more than two hosts i have this error; mpi works well on each machine and I also tried to run my program with different couple of machines in order to be sure that no machine could be the problem. Can you help me please? Ada
Re: [OMPI users] OPENMPI_ORTE_LOG_ERROR
My problem is that I have to use openmpi 1.7 rc5 because I'm using the Java binding mpijava... Is it present in the latest snapshot you told me? If so where can I find it?

Re: [OMPI users] OPENMPI_ORTE_LOG_ERROR
Hi, I've installed the latest snapshot taken from svn developer's trunk but I had the same problems. This is my configuration: - Ubuntu 2.6.38-8 kernel - Openssh_5.8p1 openssl 0.9.8o - Libtool version 2.4 - Open mpi 1.7 rc5 and latest snapshots. Do you think my problem could be related with the operating system used or with any parameter or configuration? I've also checked the ssh log file but I didn't find any problem.

Re: [OMPI users] OPENMPI_ORTE_LOG_ERROR
I'm sure that openmpi works, morever my problem happens only with more than 2 slaves (on different machines while in local it greatly works with any number of slaves).

Re: [OMPI users] OPENMPI_ORTE_LOG_ERROR
Yes I can but with at most two machines as slave and one machine as master, If I try to add another one as slave I get those errors.
