For OpenBlas, or hpl?
For hpl, I used GCC 6.1.0 with these flags. I
$ egrep -i "flags|defs" Make.gcc-6.1.0_openblas-0.2.19
F2CDEFS = -DAdd__ -DF77_INTEGER=int -DStringSunStyle
HPL_DEFS = $(F2CDEFS) $(HPL_OPTS) $(HPL_INCLUDES)
CCNOOPT = $(HPL_DEFS)
OMP_DEFS = -openmp
CCFLAGS = $(HPL_DEFS) -march=barcelona -O3 -Wall
LINKFLAGS = $(CCFLAGS) $(OMP_DEFS)
ARFLAGS = r
For OpenBLAS:
make DYNAMIC_ARCH=1 CC=gcc FC=gfortran
# This little summary is printed out at end of build:

i can't speak to AMD, but using HPL 2.1 on Intel using the Intel
compiler and the Intel MKL, i can hit 90% without issue. no major
tuning either
if you're at 33% i would be suspect of your math library
I'm using OpenBLAS 0.29 with dynamic architecture support, but I'm
thinking of switching to using ACML for this test, to remove the
possibility that it's a problem with my OpenBLAS build.
