Hello,

I'm trying to install the MPI package LAM on our IBM workstation
cluster (AIX 4.1, AFS). I got it compiled, added it to my PATH, 
but i can't boot the daemon. Is there somebody who can help me?

When invoking the boot command on my local machine (ihfibm7) 
(i wil use indents to mark screen output)

  ihfibm7> lamboot hosts                          

i get these messages:

  LAM 6.0 - Ohio Supercomputer Center

  lamboot: hboot failed on n1 (ihfibm2)
  lamboot: No such file or directory
  ihfibm7> 

The documentation of LAM says, LAM requires its binaries to be
in the PATH when using rsh (since LAM usese rsh to start processes
on other machine like ihfibm2 in the given example). So i tried to
verify the PATH when using rsh by typing

  ihfibm7> rsh ihfibm2 echo \$PATH
 
machine ihfibm2 responds with

  :/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/bin

Ok, you might say: "That's the problem, just add your LAM binary
path and it will work". That's what i'm thinking, too.
But, how can I change the above PATH? rsh invokes my ksh shell
without using the PATHS in /etc/environment, /etc/profile,
~/.profile or ~/.kshrc. And i even could'nt find the location
where the shown PATH is set.

Any of you got an idea?
