Subject [jira] [Commented] (HAMA-221) A BSP matrix multiplication implementation.
Date Sat, 17 Sep 2011 12:27:08 GMT


Thomas Jungblut commented on HAMA-221:

Played a bit with the algorithm, iterative and with the new fork/join framework in java7.

It is really cool, but it is just for quadratic matrices which length is a power of 2.
We should focus on a more general solution, shouldn't we?

I tagged the iterative solution with HAMA commentaries, how we can make a BSP out of it.

If you are interested in the fork join implementation have a look at:

Maybe if I have a bit more time later I can write a BSP version.
