Dear Ross .,

I have done it using auto ssh login
as you said

i created the keygen and created the
authorized keys

now the LAM boot works with out any error
the problem is for LAM one have to set path in the
$HOME/.cshrc file
--------------------------------------------------------------------------
[balaji_at_ACTINIDE ~/mddna]$ lamboot -v nodes

LAM 7.1.3/MPI 2 C++/ROMIO - Indiana University

n-1<16633> ssi:boot:base:linear: booting n0 (192.1.1.53)
n-1<16633> ssi:boot:base:linear: booting n1 (192.1.1.54)
n-1<16633> ssi:boot:base:linear: finished
------------------------------------------------------------------------
after that
I have user the two nodes and
sander run in both without
any error

but at the end it is giving a message in the terminal

        
        
        
        
        
        
        
        

----------------------------------------------------------------------------
It seems that [at least] one of the
processes that was started with
mpirun did not invoke MPI_INIT before
quitting (it is possible that
more than one process did not invoke
MPI_INIT -- mpirun was only
notified of the first one, which was on
node n0).

mpirun can *only* be used with MPI
programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You
can use the "lamexec" program
to run non-MPI programs over the
lambooted nodes.
-----------------------------------------------------------------------------but the run was complete !
is it a issue
thank you so much
for your help
balaji
UOM
