The following is text from emails between Phil Carns and Sam Lang about how to setup and use TAU with PVFS:

> I just remembered that I was supposed to pass along some instructions on

> also some pvfs_tau library?  I don't know if the latter has been

> about trying to get this running) let me know and I'll try to find out
