I have just gottenan evaluationcopy oftheMKL andhave successfully linked it with MS Visual Studio .NET.
As a quick test of the Level 1 BLAS, Ireplaced some functions that I wrote myself (such asmy_ddot and my_daxpy) with thecorresponding CBLASfunctions (such ascblas_ddot and cblas_daxpy).
To my surprise,the code became noticeably slower with the MKL functions.
I realize that Ihave not given many specifics, but is this kind of performancereasonable? Or have I made a mistake?
