Hi,

I compiled charm++ and barnes-charm on a linux cluster. The compilation seems to work without an error.
However, when I try running it on 4 nodes (1 core on each node) then only process 0 seems to have the "bodytab" (see the functions Main::startSimulation in Main.cpp and ParticleChunk::SlaveStart in ParticleChunk.cpp).
I get a Signal 11 on all other processes other than Process 0 when they try to access bodytab.

Also this program runs fine on 1 processor.

Did anyone see this error earlier? I don't know what could be going wrong.

Thanks,
Anirban
