Re: LAM: lam Digest, Vol 923, Issue 1

Try some simple tests:

- Does "tping -c 3" run successfully?  (It should
ping all the lamd's)
- Does "lamexec N hostname" run successfully?  (It
should run  
"hostname" on all the booted nodes)
- When you "mpirun -np 15 ring.out", do you see
ring.out executing on  
all the nodes?  (i.e., if you ssh into each of the nodes and
run ps,  
do you see it running?)
