i had tried setting PATH, but LAM/MPI TEST via PBS FAILED again.
with the message error in the file lamtest.err :
ERROR: LAM/MPI unexpectedly received the following on stderr:
kimia-10.chem.itb.ac.id: Connection refused
-----------------------------------------------------------------------------
LAM failed to execute a process on the remote node "kimia-10.chem.itb.ac.id".
LAM was not trying to invoke any LAM-specific commands yet -- we were
simply trying to determine what shell was being used on the remote
host.
LAM tried to use the remote agent command "rsh"
to invoke "echo $SHELL" on the remote node.
This usually indicates an authentication problem with the remote
agent, or some other configuration type of error in your .cshrc or
.profile file. The following is a list of items that you may wish to
check on the remote node:
- You have an account and can login to the remote machine
- Incorrect permissions on your home directory (should
probably be 0755)
- Incorrect permissions on your $HOME/.rhosts file (if you are
using rsh -- they should probably be 0644)
- You have an entry in the remote $HOME/.rhosts file (if you
are using rsh) for the machine and username that you are
running from
- Your .cshrc/.profile must not print anything out to the
standard error
- Your .cshrc/.profile should set a correct TERM type
- Your .cshrc/.profile should set the SHELL environment
variable to your default shell
Try invoking the following command at the unix command line:
rsh kimia-10.chem.itb.ac.id -n echo $SHELL
You will need to configure your local setup such that you will *not*
be prompted for a password to invoke this command on the remote node.
No output should be printed from the remote node before the output of
the command is displayed.
When you can get this command to execute successfully by hand, LAM
will probably be able to function properly.
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------
lamboot encountered some error (see above) during the boot process,
and will now attempt to kill all nodes that it was previously able to
boot (if any).
Please wait for LAM to finish; if you interrupt this process, you may
have LAM daemons still running on remote nodes.

It seems that there is no lamd running on the host kimia-11.chem.itb.ac.id.
This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for the "mpirun" command.
Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.
