[mvapich-discuss] vapi error on scyld configuration

[Matt Funk]

Hi Abhinav,

thank you very much for the advice.

My only question before i begin is whether i can do this without admin 
privileges? I am only a user on the machine. I have asked the admin to 
upgrade several times, but nothing has happened. He says that he hasn't 
received any new software from the vendor.


thanks
mat
