Re: [eigen] Parallel matrix multiplication causes heap allocation

[ Thread Index | Date Index | More Archives ]

I've just started to merge some support for the libxsmm matrix multiplication kernels into Eigen. These kernels are extremely efficient and perform better than the Eigen ones on Haswell and above.

Note that there is more work to be done, in particular wrt to multi-threading. This will be done over the next few months.

For the KNL, I have access to one of them but the performance is
awful compared to what I had this summer. So I would not trust it.

I could try to reproduce your results on KNL, especially if given copy&paste instructions for setting everything up. I did upload some results in in case that's relevant here.
