Subject [jira] [Commented] (HAMA-221) A BSP matrix multiplication implementation.
Date Sat, 17 Mar 2012 12:03:38 GMT


Thomas Jungblut commented on HAMA-221:

Very simplistic first working scratch of the normal matrix multiplication:

It uses row and column partitioning and a bit of messaging.
However this can be much more improved.

bq.I think it'd be nice also to implement the well known algorithms Cannon and DNS using BSP
model and eventually add them to the hama-examples module.

Do you have some papers for them? Especially MPI versions can be very well translated to BSP
I've seen ;)

This is a good example for DNS:
