Ivan,

I must say, the PGI compilers have provided a 20% speedup on some apps for 
us, and we only have one licence on the master node.  However, if it was 
not for PGI being the only PC compiler that supports Cray Pointers and our 
users extremely legacy f77 code, I think we would use gcc only.  But i've 
experienced no problems with just having the compiler on the master, and 
using that binary on the compute nodes.  The only place I could see needing 
it on more than just the master is if you don't have a homogenous cluster.

HTH,
Doug
