I'm not 100% certain of the current status of Nemesis+PGI.  Nemesis  
depends on  the OPA library in order to get atomic assembly  
instructions for some of the shared memory communication.  At least as  
of a while ago, OPA still didn't work on PGI because of some bugs in  
the PGI compiler itself.

Darius might know the status with greater certainty.  If not, I can  
play with it on Monday or Tuesday and get back to you to see where we  
are at w.r.t. PGI.

What version of the compiler are you using?  If things are going to  
work at all, you'll probably need a fairly recent version.  We have  
7.1 and 8.0.5 here at ANL, and I'm fairly certain that it will not  
work with 7.x, but I'm not sure about 8.x.  And I haven't used the 9.x  
series yet at all.  I just tried to test things with 8.x, but our  
license server is having some trouble after a datacenter move this  
weekend.  I'll let you know more once we get that sorted out this week.
