Re: [OMPI users] error performing MPI_Comm_spawn

Okay, I can replicate this. FWIW: your test program works fine with the OMPI trunk and 1.3.3. It only has a problem with 1.4. Since I can replicate it on multiple machines every single time, I don't think it is actually a race condition. I think someone made a change to the 1.4 branch that cre

Re: [OMPI users] How to detect a failure to start-up and MPI_Init()?

Finally got time to look at this - not sure this is a bug, if I understand correctly your scenario. When you say the application exits, do you mean it calls "exit" - or do you mean it segfaults or some other such abnormal termination? Reason I ask: if the process has not yet called MPI_Init and

Re: [OMPI users] OpenFOAM fail to run under openmpi-1.3.3 on 2x Ubuntu 9.10 x64 Server

Your path on a remote node is wrong and so OMPI cannot find the required OMPI executable ("orted") to launch your job. Check your path to ensure that it is getting setup correctly on your remote nodes - every node needs to see you OMPI installed binaries and libraries. On Dec 15, 2009, at 10:4

Re: [OMPI users] NFS and openmpi through different NICs

Hi Dmitry Yes, we do it here. Besides Bill's recommendations you can also use different host/interface names for, say, eth0 and eth1, in /etc/hosts. Moreover, you should set OpenMPI to use only the specific subnet/ports you want to dedicate to MPI, say, eth1. See these faq: http://www.open-mpi

Re: [OMPI users] error performing MPI_Comm_spawn

Looks to me like it is a race condition, and the timing between 1.3.3 and 1.4 is just enough to trip it. I can break the race, but it will have to be in a future fix release. Meantime, your best bet is to either stick with 1.3.3 or add the delay. On Dec 15, 2009, at 5:51 AM, Marcia Cristina Cer

[OMPI users] error performing MPI_Comm_spawn

Hi, I intend to develop an application using the MPI_Comm_spawn to create dynamically new MPI tasks (or processes). The structure of the program is like a tree: each node creates 2 new ones until reaches a predefined number of levels. I developed a small program to explain my problem as can be se
