p4 v itinium

[Ricky Rankin]

I am currently looking to setup a linux cluster for use by 
researchers in the University. I would appreciate any views on 
the following:-

can a p4 access more than 4GB memory - some of the codes have a 
requirement to access large memory

if I have to go to itanium, is there a reliable fortran compiler 
for this platform

if p4 can access greater than 4GB memory are there any 
preformance gains in going for the more expensive itanium option

Thanks
Ricky
