[Pw_forum] Compiling pwscf using ifc 7.1 on a x64-64 system

[Jonathan Breeze]

As far as I know, IFC can only generate 32-bit code that is compatible 
with an AMD64 processor.  There is a version for IA-64 chips but I don't 
think it would be compatible with AMD64.  The  PGI compiler can generate 
64-bit code apparently, I'll be trying that next I think, then I will be 
able to compare performance.
