Dear Gus Correa, Thank you in advance for your detailed answer. I was busy checking your steps. But unfortunately still I have the problem. 1) Yes, I have sudo access to server, when I want to run the test only my two instances are active. 2) There is no problem with running hello program simult

Hi Reza It is hard to guess with little information. Other things you could check: 1) Are you allowed to increase the stack size (say, by the sys admin in limits.conf)? If using a job queue system, does it limit the stack size somehow? 2) If you can compile and run the Open MPI examples (hello_

I agree with Gus - check your stack size. This isn't occurring in OMPI itself, so I suspect it is in the system setup. On Apr 3, 2013, at 10:17 AM, Reza Bakhshayeshi wrote: > Thanks for your answers. > > @Ralph Castain: > Do you mean what error I receive? > It's the output when I'm running t

Thanks for your answers. @Ralph Castain: Do you mean what error I receive? It's the output when I'm running the program: *** Process received signal *** Signal: Segmentation fault (11) Signal code: Address not mapped (1) Failing at address: 0x1b7f000 [ 0] /lib/x86_64-linux-gnu/libc.so.6

Hi Reza Check the system stacksize first ('limit stacksize' or 'ulimit -s'). If it is small, you can try to increase it before you run the program. Say (tcsh): limit stacksize unlimited or (bash): ulimit -s unlimited I hope this helps, Gus Correa On 04/03/2013 10:29 AM, Ralph Castain wrote:

Could you perhaps share the stacktrace from the segfault? It's impossible to advise you on the problem without seeing it. On Apr 3, 2013, at 5:28 AM, Reza Bakhshayeshi wrote: > ​Hi > ​​I have installed HPCC benchmark suite and openmpi on a private cloud > instances. > Unfortunately I get Seg

​Hi ​​I have installed HPCC benchmark suite and openmpi on a private cloud instances. Unfortunately I get Segmentation fault error mostly when I want to run it simultaneously on two or more instances with: mpirun -np 2 --hostfile ./myhosts hpcc Everything is on Ubuntu server 12.04 (updated) and th
