LAM: lam-hostmap problem

Hello,

Lam version : 7.1.2
Linux kernel 2.6.15-20-amd64-k8 on a x86_64 host.

I use the lam-host to remap mpi connections on high
bandwitdh links. I have 17 hosts running with lam.

If I try to run a program using more than 2 processes with
remapping on, the application hangs
during MPI_Init.

If I run the same program with -ssi mpi_hostmap none, the
application always work.

Is this a known problem ?

	Regards,
	Romaric

Hello,

Forget it : it was caused to a network layer 2 problem (we
use Lacp for agregating bandwith,
and we have problems combining LACP and Jumbo Frames).

Sorry for the trouble,

	Romaric
