[mvapich-discuss] Uninstalling mvapich

[Jack Poulson]

James,

I'm assuming you have root access. If so, run:
sudo find / -print | grep mvapich

If you don't have root access, you must be installing in your home
directory, so run:
find ~ -print | grep mvapich

If anything shows up, delete it.

Regards,
Jack
