Sorry about the blank response (phone keypad challenged, I am).
LAM/MPI is one of several open source implementations of the MPI
standard. There are commercial ones as well. Open-MPI is a combination
of several earlier implementations, including LAM. I suggest you go to
the open-mpi web site and read the FAQ, as a start.
Cheers,

Hi,
LAM has not been maintained for quite some time. I highly
recommend you try www.open-mpi.org instead .

Subject: LAM: recon gives ERROR: LAM/MPI unexpectedly received
the following on stderr: bash: tkill: command not found
when i run recon -v hostfile
the error says it could'nt find tkill in $PATH
ERROR: LAM/MPI unexpectedly received the following on stderr:
bash: tkill: command not found
LAM failed to execute a LAM binary on the remote node
"10.5.18.46".
Since LAM was already able to determine your remote shell as
"tkill",
it is probable that this is not an authentication problem.
*** PLEASE READ THIS ENTIRE MESSAGE, FOLLOW ITS SUGGESTIONS, AND
*** CONSULT THE "BOOTING LAM" SECTION OF THE LAM/MPI FAQ
*** (http://www.lam-mpi.org/faq/) BEFORE POSTING TO THE LAM/MPI
USER'S
*** MAILING LIST.
LAM tried to use the remote agent command "/usr/bin/ssh"
to invoke the following command:
/usr/bin/ssh -x -a 10.5.18.46 -n tkill -N -d
This can indicate several things. You should check the
following:
- The LAM binaries are in your $PATH
- You can run the LAM binaries
- The $PATH variable is set properly before your
.cshrc/.profile exits
Try to invoke the command listed above manually at a Unix
prompt.
surprisingly .. i could'nt invoke the command manually too ..
the path is set correctly ..
I am able to invoke "tkill" independently(seperately by logging
into ) on the other node(10.5.18.46) which proves that the path is set
properly .. but the command
/usr/bin/ssh -x -a 10.5.18.46 -n tkill -N -d
would still give the error!!!!!
bash: tkill: command not found
please help me with the issue ..
