Subject [jira] Commented: (HAMA-121) default maximum block size
Date Thu, 04 Dec 2008 14:15:44 GMT


Samuel Guo commented on HAMA-121:

I think we may consider the cpu's cache size to decide the default maximum block size.
A suitable block size will reduce cpu cache hit misses during *SubMatrix* multiplication.
Or we may change the *mult* method's implementation of *SubMatrix* to match a cpu's cache
working pattern.

I think we may do some experiments over *SubMatrix* to know a suitable size.
