Vector pw multiplication on Itanium

Hi all.

I'm serching for a routine to do pointwise multiplication of two double precision vectors (something like a vdMul in VML library)

I already saw a message about this topic, about the __mm_mul_pd instrinsic, but this intrinsic is a SIMD 2 (only works for Pentium4).

Any body have a hint to solve construct a vdMul function?

Thanks.

Hello,

Intel compiler should perform well on pointwise multiplication. Did you try the compiler? I wounder if adding this feature to MKL would bringsome benefit compared to the compiler generated code.

I completely concur with Sergey.
