[lammps-users] Benchmark of granular flow

first off. please always keep the list in cc.
people on the list should know the resolution
to questions, so that they can search the archive
for solutions. i will not reply to future responses
that are only sent to me.

Thanks Axel for reply. But I am sure that, there is no hardware or
cooling problem because it was running fine for other codes

sorry, but that doesn't prove anything. different
software can strain a machine in very different ways.

i can run the in.chute example on my machine without
a problem on one and many processors.

I think there must be some other problem.

you didn't really answer my question. does your machine
crash hard or is it just lammps that crashes?

axel.

my machine got crashed not just lammps, that's why i have to turn off
the power and reboot the system again. Even at the time crashing, my
system is not too hot.
I just tried with different machine, it is running fine with larger
time steps on that machine, but that machine contains 8 processors and
16 GB memory. and my earlier machine contains only two processors and
2 GB memory. But even in the new machine I am running lammps on a
single processor.
Does the configuration of the machine makes the difference?

Thanking you

then something _is_ wrong. as i wrote before. if lammps is
able to crash your machine hard, then your hardware has a problem.
the list of possible reasons is long and it is impossible to
debug over e-mail. get somebody with proper technical knowledge
and let him or her check out your machine.

no. lammps is running as an unprivileged user application.
it has no access to any part of the operating system that
can cause a crash, so if your machine crashes hard, it has
to be a hardware problem. simple as that.
