Hmm, interesting. I thought I was doing something wrong while trying to
execute make test.parallel when in fact it was something screwy with the
compiled binaries of lam. I recompiled LAM and now it works.
 
For future reference:
 
On the head node:
# chmod -R a+w $AMBERHOME/test
# su myuser
$ cd $AMBERHOME/test
$ export DO_PARALLEL='mpirun -np 4'
$ make test.parallel
 
Thanks for the suggestion,
 
Mike

If you indeed get the "same error" (there is no lamd running on the
host), then
the problem with with lam, not with amber. Did "lamboot" give any reply
(it should
spit out the version number, etc. to the screen). You can run
"lamnodes" to see what
lam thinks is happening. Have you run simple MPI test cases with lam?

...good luck...dac
