For those of you in this situation, you can apply the attached patch to your OMPI 1.3.1 source code and rebuild it - has been tested by the original reporter and it solved this particular problem. Ralph changeset_r20856.diff Description: Binary data On Mar 24, 2009, at 5:44 PM, Divya N

Hi, Ran into the same problem yesterday and was wondering what was wrong. Couldn't get that fixed even after I read the users archives. Thanks for this response. So, there's no way as of now to get openmpi running on a laptop with ubuntu? Thanks, Divya On Tue, Mar 24, 2009 at 7:33 PM, Ralph Cast

Yeah, there is something funny about the way Ubuntu is defining their Ethernet interfaces that is causing a problem. I have a patch that will be in 1.3.2 that fixes the problem. On Mar 24, 2009, at 5:24 PM, Simone Pellegrini wrote: Hello everyone, I have the same problem when I try to inst

Hello everyone, I have the same problem when I try to install openmpi 1.3.1 on my laptop (Ubuntu 8.10 running on a dual core machine). I did the same installation on Ubuntu 8.04 and everything works, but here no matter what I do, every time I type mpirun the system prompt for the password.

[OMPI users] Possible regression from 1.2 to 1.3 when BLACS is involved

2009-03-24 Thread Åke Sandgren
Hi! We're having problems with code that uses BLACS and openmpi 1.3.x. When compiled with memory-manager turned on (base only), code using BLACS either start leaking memory or gets into some kind of deadlock. The first code-case can be circumvented by using mpi_leave_pinned_pipeline 0, but the sec

Hi Manuel ! I read what you said on the web before I sent my email. But it does not work with my sample. It is an old LAM source C. Anyway, thanks a lot for your reply. Jerome Manuel Prinz wrote: Hi Jerome! Am Dienstag, den 24.03.2009, 16:27 +0800 schrieb Jerome BENOIT: With LAM some configu

Hello List, I have just installed OpenMPI on a Lenny cluster where SLURM works fine. I can compile a sample C source of mine (I used LAM a few years ago), but I can not run it on the cluster. With LAM some configuration files must be set up, I guess it is the same here. But as SLURM is also invo
