Dear Beowulf Community members,
I am planning to build a Beowulf cluster of 12 SUN FIRE 2200 boxes
with Opteron-2.6GHz processor (Dual Core). The purpose of this
cluster is to run my Amber9 code. I want to know one thing, Would
the Opteron can give better benchmarks if I compile my Amber9 with
Intel MKL and ifort compiler? I googled around it, but I could not
get any positive or negative results either. I am looking for
expertise and experinced advices and suggestions. Many thanks in
advance.
AFAIK programs compiled with ifort run best on Intel CPUs, as
otherwise only a generic version of the code is used.
But checkout the -xO switch in their 10.0 release, which will use
SSEx commands also on Opterons.
