Overview

ITXGEMM is an implementation of matrix-matrix multiplication that builds on some recent theoretical results of ours that show how to take advantage of all layers of memory hierarchies on modern microprocessors. The project is a collaboration between Greg Henry at Intel (R), and John Gunnels and Robert van de Geijn at The University of Texas at Austin.

Future Directions

We have a full set of level-3 BLAS coded using FLAME . They attain performance similar to the LU factorization in the performance web page. They will be released shortly. Get on our mailing list to remain informed.

The IA-64 will be targeted next.
