Hi Guys
This is a quick question regarding the xhpl benchmark.
I assume you mean the HPL benchmark. xhpl is its executable name.
Im no
mathematician but im trying to understand how the benchmark operates.
I would like to test my system by seeing how many FLOPS are achieved
using only the Matrix Multiply.
You could probably download the HPC Challenge benchmark (from
http://icl.cs.utk.edu/hpcc/software/index.html ) and cut-paste some code from
it's DGEMM (Double-precision, GEneral Matrix-Multiply) sub-benchmark as a
relatively easy way to get a test program for matrix-multiply.
DGEMM is typically ~90% or more of the HPL benchmark's profile.
-Tom
Is there a way to configure the benchmark so that only the Matrix
Multiply routines are run? does it only perform a Matrix Multiply? Im
sorry for such a lame question but its not clear to me from the
documentation.
Thanks for looking
Matt
