Dear Gadget-2 Users,

I ran into a domain decomposition error while trying to run Gadget-2
with 1024 cores. Here's a copy what the log says (shortened):
...
Total number of particles : 0134217728

allocated 0.0762939 Mbyte for ngb search.

Allocated 16.6029 MByte for BH-tree. 64

domain decomposition...
_pmii_daemon(SIGCHLD): PE 996 exit signal Killed

... (goes on and on with all PEs)

_pmii_daemon(SIGCHLD): PE 888 exit signal Killed
Application 57082 exit codes: 137
Application 57082 exit signals: Killed

I have run the same IC file with 512 and 64 cores without any problems
so the problem must be related to the number of PEs. However, I did
not change any Makefile or parameter file options when I moved from
512 (or 64) to 1024 cores, so everything in these files should be ok.

The IC file I'm running contains 512**3 particles in a 20/h Mpc box on
side, but I doubt it matters.


Thanks in advance,
Sami
