mkl vs ipp for eigenvalues

mkl vs ipp for eigenvalues

Hello

I have a signal processing task which the heaviest operation is finding the eigenvalues and eigenvectors of a 128x128 Hermitian matrix. I found routines both in ipp and in mkl. Which one will be faster? I am using standard i7 windows 64 with 16Gb memory. 

Regards

Dani

Dani,

MKL is a better choice, as IPP is typically optimized for very small matrix size (3x3, 4x4, etc). For such size of problem, you can choose MKL.

Thanks,
Chao

IPP has a set of functions for finding eigenvalues of symmetric and non-symmetric matricies and take a look at a ippm.h header file.
