ubuntu 11.10 rebooting while using all 8 processors using mpirun

Submitted by Tamoghna on Fri, 11/11/2011 - 17:05

Hi!

I am new with linux,

I have a machine with 8 Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz processors.

I am using the following command for multi processor simulation in liggghts.

mpirun -np 8 liggghts < in.rot_chute

The program is running good for sometime after which the systems reboots in itself.

I know that it is not directly related to liggghts, but, it would be great if you could give me some indication about the source of problem. I also tried with 6 processors with same problem.

Could you please tell me what could be possible solutions for the same?

hard to say, could be a memory chip error, an OS related issue...
could be temperature related - you could try if it occurs also for low loads (e.g. if you run just with 1 proc)
