dgemm_ vs. cblas_dgemm

Hello,

I'm doing some performance benchmarks on Intel's mkl right now and I noticed some unexpected issues. When using dgemm_() function instead of cblas_dgemm() on the same matrix I get around 4 times fewer Gflop/s. It's the same either with the non-parallel and parallel version.

Did someone experience similiar things or could probably point me to a possible failure?

Thanks
