Unable to execute Gadget2 beyond 828 cores.

Dear all,

I have been trying to execute Gadget2 on 70 nodes with 12 cores per node
(total number of cores = 840). But I can see the following errors:

reading file `../ic_pckg/ICs/test.1' on task=3 (contains 262144 particles.)

distributing this file to tasks 3-3

Type 0 (gas): 0 (tot= 0000000000) masstab=0

Type 1 (halo): 262144 (tot= 0134217728) masstab=0.969332

Type 2 (disk): 0 (tot= 0000000000) masstab=0

Type 3 (bulge): 0 (tot= 0000000000) masstab=0

Type 4 (stars): 0 (tot= 0000000000) masstab=0

Type 5 (bndry): 0 (tot= 0000000000) masstab=0



too many particles
task 3: endrun called with an error level of 1313

Similar errors can be seen on 69 nodes (total cores = 828) also, but the
code goes through this phase on 816 cores (68 nodes with 12 cores each).

Do I need to change any parameters in the lcdm_gas.param or *ics.param *
files?

Kindly advise.

Thanks!
