compilation - not running on more than 3 processors

LAMMPS LAMMPS Mailing List Mirror

Dear all,
I am compiling recent version of lammps dated 17jun 2011. I compiled it successfully. I can use it in parallel with 3 or less than 3 processors. But when i try to use more than three, it is giving following error.

Scanning data file …
2 = max bonds/atom
1 = max angles/atom
Reading data file …
orthogonal box = (-20.5 -20.5 -20.5) to (20.5 20.5 20.5)
1 by 2 by 2 processor grid
rank 2 in job 1 kamadhenu_40845 caused collective abort of all ranks
exit status of rank 2: killed by signal 11

I could compile previous versions and ran them successfully in parallel.

Thanks for your help.

Regards,
Sandeep

Dear all,

dear sandeep,

          I am compiling recent version of lammps dated 17jun 2011\.  I

the current version is 27August2011

compiled it successfully. I can use it in parallel with 3 or less than 3
processors. But when i try to use more than three, it is giving following
error.

Scanning data file ...
2 = max bonds/atom
1 = max angles/atom
Reading data file ...
orthogonal box = (-20.5 -20.5 -20.5) to (20.5 20.5 20.5)
1 by 2 by 2 processor grid
rank 2 in job 1 kamadhenu_40845 caused collective abort of all ranks
exit status of rank 2: killed by signal 11

with this information it is impossible to tell what is going on.

does this happen to _any_ of the example inputs shipped with lammps?

or only to _your_ input?

cheers,
