Performance benchmarking with open64 and acml_mv

I try to compare the latest open64 and acml math library with Sun Studio 12 update 1(ss12u1). The result shows open64 generated executables are 10-25% slower than ss12u1. Only on fma3d_m open64 gives better result.

The options I use are:

FOPTIMIZE = -Ofast -mp -HP -mso -LNOrefetch=3 -LNO:simd=1 -LNO:vintr=1 -march=barcelona
COPTIMIZE = -Ofast -mp -HP -mso -LNOrefetch=3 -LNO:simd=1 -LNO:vintr=1 -march=barcelona
EXTRA_LDFLAGS =
EXTRA_LIBS= -I/opt/acml4.3.0/open64_64/include -L/opt/acml4.3.0/open64_64/lib -lacml_mv

Has anyone run specOMP with open64? I searched spec result site and cannot find any result using open64.

Thanks,

Jun
