[mvapich-discuss] how to set "ulimit -l unlimited" at user level?

[Joshua Bernstein]

Also,

	If you are running AMBER with using SSH, you will want to add the 
ulimit -l command to your /etc/init.d/sshd startup script on the nodes. 
That way any proces forked by SSH on the compute node will inherit that 
setting and hence allow AMBER to run.
