[OMPI users] Behaviour of MPI_Cancel when using 'large' messages

The following code tries to send a message, but if it takes too long the message is cancelled: #define DEADLOCK_ABORT (30.0) MPI_Isend(message, count, MPI_BYTE, comm_id, MPI_MESSAGE_TAG, MPI_COMM_WORLD, &request); t0 = time(NULL); cancelled = FALSE; while(TRUE) { //do som

[OMPI users] ompi-restart, ompi-ps problem

Hello, I'n trying to get functions like orte-checkpoint, orte-restart,... works but there are some errors that I don't have any clue about. Blcr (0.8.2) works fine apparently and I have installed openmpi 1.4.2 from source with option blcr. The command mpirun -np 4 -am ft-enable-cr ./checkpoint_

[OMPI users] ompi-restart failed

Hello everyone, I'm using OpenMPI 1.4.2 with BLCR 0.8.2 to test checkpointing on 2 nodes but it failed to restart (Segmentation fault). Here are the details concerning my problem: + OS: Centos 5.4 + OpenMPI configure: ./configure --with-ft=cr --enable-ft-thread --enable-mpi-threads \ --with-blcr=

Re: [OMPI users] ompi-restart failed

George -- Scott's patch was different than the one you applied. Apparently, his fixes this user's problem (I don't know if Guillaume tested yours). Which one wins? On Jun 3, 2010, at 9:49 AM, Scott Atchley wrote: > On Jun 3, 2010, at 8:54 AM, guillaume ranquet wrote: > > > granquet@bordepl

Re: [OMPI users] Process doesn't exit on remote machine when using hostfile

Hi, The hostfile seems working for me on my Windows XP machines, but it should be the same on Windows 7. The problem you had looks to me more like a synchronization problem. Could you send me your test program? Regards, Shiqing On 2010-5-25 11:41 AM, Rajnesh Jindel wrote: disabled the fir

Re: [OMPI users] Behaviour of MPI_Cancel when using 'large' messages

Hello Gijsbert, I had the same problem few months ago. I even could not cancel the messages for which I did not have a matching receive on the other side (thus, they could not have been received! :-)). I was wondering really what was going on... I have some experience with MPI, but I am not an exp

[OMPI users] segfault with -pernode on 1.4.2

Dear All, I recently installed 1.4.2 version, and am having a problem specific to this version only (or so it seems). Before I lay out the details please note that I am building 1.4.2 *exactly* the same as I built 1.4.1: same compiler options, same OpenIB and other system libraries, same configur

Re: [OMPI users] segfault with -pernode on 1.4.2

Thanks for reporting this. -pernode is just -npernode 1 - see the following ticket. Not sure when a fix will come out. https://svn.open-mpi.org/trac/ompi/ticket/2431 On Jun 7, 2010, at 4:27 PM, S. Levent Yilmaz wrote: > Dear All, > > I recently installed 1.4.2 version, and am having a probl
