Hi Intel, so I was pretty excited when I fired up my new Core i7 2600K and achieved 135GFLOPS inMKL linpackright off the bat.
Now I had read on MKL product pages that MKL LAPACK uses AVX, so I was expecting some performance boost for the parts of my science code that spend a long time solving eigensystems using ZSTEMR. But it was not to be! I ran my code and found only a small improvement.
So, I've now discovered that only a very few LAPACK and BLAS functions use AVX as of MKL 10.3.
My question is, can we expect more widespread support in the next version of MKL? Will AVX allow for a large (50-80%) speedup for solving eigensystems? When can we expect this stuff added to Intel MKL?
Thanks for any info!!
