Salut Clement


-check against which lam / mpi Version your LS Dyna was built
 ( ldd mpp_ls971..... )

-then for a start do a "manual"  lamboot without batch system
 locally on a two CPU node


if the lam/mpi binary connects well to lam, repeat those steps for two
different nodes with real network communication

to give feedback for debugging: We have every existing dyna Version
running well with lam / mpi

The only issues are:

-use the lam/mpi against which dyna was built

-integrate the lam / mpi start into the batch system
 ( there you have different choices )
 if you have problems getting started, do in a bazch script exactly
 the same steps you would do manually

I don't see anything wrong when I execute the ldd :

Everything works fine when i run on each node lamboot and after the mppdyna on this node, but it crash when I launch lamboot on two nodes and I run mppdyna on this two nodes.

I use lam 7.0.3 without the batch system at the present time.
Thanks for your help.

Clément.
