[Beowulf] PVM or ???

Hello Timo,

I have been using Rocks on my test cluster and am planning to use it in 
my production environment by next month. Although i have not used rocks 
at production level but i have been using rocks for over 6 months and 
have not used it's XFree86 at all. Since i generally monitor and 
administer my cluster remotely XFree86 is of limited use for me.  I 
generally configure X with a ssh and X11 forwarding on and then 
configure the vncserver that i can  remotely log in with GUI interface 
if required.

On a different note it would be more practical to get a new graphics 
card that is supported with a distribution that will help you manage the 
cluster more efficiently rather than going with a distribution that 
supports your video card and does not provide enough flexibility.

Thanks

Anand Singh Bisen
