Subject Re: How to write my application over Hama?
Date Mon, 03 Mar 2014 04:14:22 GMT
As I mentioned before, MR based algorithms are not efficient and
scalable with heavy IO. Latest version doesn't provide a matrix
library, you should write your own application.

See BSP program turotial - http://hama.apache.org/hama_bsp_tutorial.html

and SUMMA and Sparse SUMMA.
