Hi:
I just ran across this while running GPU benchmarks, but I'd like to see
if maybe I'm missing something:
The Makefile in amber11/src/pmemd/src has load lines that begin:
$(PMEMD_LD) $(PMEMD_OPTFLAGS) .....
The problem is that PMEMD_OPTFLAGS is *not* set in config.h; this looks like
a typo, and should be $(PMEMD_FOPTFLAGS).
The upshot is that pmemd with a stock compile (using Intel compilers)
does not have the -fast flag passed to the loader, leading to severe
reductions in performance (greater than three-fold slowdown for me).
It's a simple bugfix, but I don't want to be chicken-little if I am missing
something here....Can someone (Ross?, others) look into this?
...thanks....dac
