Hi !

I'm using mpich with arch=freebsd and device=ch_p4 on a homogenous Cluster of 
17 FreeBSD3.0 machines.
There's a strange problem - if i start a sequence like:

mpirun -arch freebsd -np 4 -nolocal -v cpi

everything is fine. But If I switch onto more machines like 8 or 10 to 16, I
always get timeouts by p4 like this one:

p12_966: p4_error: Timeout in establishing connection to remote process: 0

I tried to set up the p4-servers, tried other examples - always the same error.

Is this a configuration problem ? Where can i find a bit more detailed
messages concerning p4 errors ? Is there a way to examine what exactly
is going on ?

Please help

Bye

Gunther Hipper
