Hi David,
You are correct-- g77 is not installed on every node. I ssh to each node
and perform which g77 and get no response. What is the easiest way to
install g77 on every node (WITHOUT ROOT PRIVILEGES)? If I install in my
home directory, will it propagate to every node? I have access to a
directory which is above my home directory which I use for other installs
and is accessible to all nodes. Which do you recommmend? And finally, what
env vars need to be set, etc, to ensure that the g77 will be visible to each
node?
Thanks again,
Frank
