I have a benchmark application that mainly does two types of things:
* Eigenvector decompositions
In both cases, the new MKL11 benchmarks much slower than MKL10 on a I7 IVY Bridge, Sandy Bridge and other CPUS.
For the Eigenvector code, it is about 1/2 the performance in version 11. For the FFTs the performance is degraded by about 30%.
Is there a reason why MKL 11 performs worse? Is there something I need to do to at least get equivalent performance to MKL 10?
Thanks for your assistance in advance.
