An update...
I tried adding mcmodel=medium to the compiler flags... not much useful tbh!!! I then read on the wiki (should have checked first!!) that inserting CMK_THREADS_USE_CONTEXT 1 into conv-mach.h can help with the segfault problem... a recompile later and :

I don't know how these times compare but I'm running opteron 1.8/2 Ghz (not sure which ones are in the node I ran on) with GigE interconnect

Subject: namd-l: Compilation of Charm++ then NAMD 2.6 on Opteron with Portland compilers
Hi,
I'm having some issues compiling Charm++/NAMD on our opteron based cluster. I've read somewhere that it is best to use the fastest compiler. I think I've just about got Charm++ working, and it works fine with the simplearrayhello, and I've compiled the megatest program.. the only error I got was an error from pgCC saying that -rdynamic is an unknown switch. If I run on 4 procs I get the following output:
Megatest is running on 4 processors.
test 0: initiated [groupring (milind)]
test 0: completed (45.86 sec)
test 1: initiated [nodering (milind)]
test 1: completed (45.36 sec)
test 2: initiated [varsizetest (mjlang)]
test 2: completed (0.27 sec)
test 3: initiated [varraystest (milind)]
test 3: completed (0.32 sec)
test 4: initiated [groupcast (mjlang)]
test 4: completed (1.57 sec)
test 5: initiated [nodecast (milind)]
test 5: completed (0.96 sec)
test 6: initiated [synctest (mjlang)]
**ERROR: in routine alloca() there is a
stack overflow: thread 0, max 535822332KB, used 2KB, request -1082359024B
Could anyone elaborate on what's wrong here, I heard that the Megatest program tests things that are fairly crucial to NAMD's running?
