Sparse, Hermitian Matrix-vector multiplication

riccardi — Fri, 11 Apr 2008 22:01:04 GMT

Hello,

Are there any routines for matrix-vector multiplications involving complex, sparse matrices and vectors? like say, mkl_Zcoogemv for coordinate storage.

Thank you.

Dear Demian,

The currentMKL Sparse BLAS only suppots double precision. Support of other types (single, complex and double complex) in MKL Sparse BLAS is under integration inot MKL and new routines willbe availablein the next MKL 10.1 Beta.

All the best

Sergey

Hello Sergey,

Thanks for your response. Do you know when the MKL 10.1 beta will be released? This is not the update that was just released (10.0 update 3), correct?

Demian,

That's right; MKL 10.0 update 3 which was just released does not have the new sparse BLAS functions.

These will be available in one of the beta releases for version 10.1. Well be announcing those here as they become available along with a list of the new features available in each.

I should have added that you can pre-register here and youll be sent an email when the beta program begins. You may already have noticed the beta announcement, where some of the coming improvements are outlined.
