Oh, sorry. I just deleted that phrase. I'd like to say that the main goal of Hama (Hadoop Matrix) project is a high-performance distributed matrix/graph computing solution. We won't implement a algorithm library. In the future, the Hama will consists of the BSP computing engine, and a set of few examples (e.g., matrix inversion, pagerank, ..., etc).
Of course, If someone contribute a nice and clean patch such as, a implementation set of some algorithms or matrix/graph computing framework based on Hama BSP, we'll accept them. Is it clear enough for you? Thanks. :) On Thu, Jul 15, 2010 at 3:03 PM, Guo Leitao <[email protected]> wrote: > That's great if 'Hama project goal is still a distributed matrix/graph > computing framework', but from the former mail communication, seems Hama > 'aims at a distributed scientific package on Hadoop for massive matrix and > graph data'.
