Dear amber user,

i try to run amber6 using cluster mini cluster consist of 1 server (xeon -
redhat 3 AS enterprise ed.) and 8 nodes (pentium 4 - redhat 3 AS enterprise
ed.).. but it failed.. then i check again my mpi (mpich-1.2.6) wether it is
working or not.. what i do is just 'mpirun -np 4 cpi' in

after that i get this error msg :-

[ghaniee_at_alpha examples]$ mpirun -np 4 cpi
alpha1: Connection refused
p0_2783: p4_error: Child process exited while making connection to remote
process on alpha1: 0
/usr/local/mpich-1.2.6/bin/mpirun: line 1: 2783 Broken pipe
/usr/local/mpich-1.2.6/examples/cpi -p4pg /home/ghaniee/PI2662 -p4wd

can someone help me to solve my problem? why is the connection refused? for
your information i can ping to the nodes.. i can rsh without password by
using user account and also by using root.. i can ssh (but with
password)... i hope there is someone out there can help me..
