Small Matrix/Vector Functions alternative?

Hi everyone,

I am shocked to find out the small matrices and vector part of the IPP got removed.

In short, what would be an alternative regarding ease of use and performance?

Greetings from Germany,

Hendrik,

Have you got the chance to review Intel MKL library? Do you see any gap when moving your code to this library:

Thanks,

Hello Chao,

Thanks for that link. It helps alot.

We had a look at the MKL and yes, it provides the functionality. Fortunatly we are starting a fresh project, so no legacy code to adapt.

But the difference in the interface definition are somewhat hard for me (personally) because I used the ippvm for 5 years. Instead of Matrix x Vectorarray, I have to think of Matrix x Matrix e.g. - but that's not somethink I should be able to adapt quick.

I have a bit more concerns about the performance - but relating to that article, the MKL got / will get better for small matrices.

Regards

Hendrik
