BSP
The BSP package is a implementation of BSP over Hadoop RPC(sockets). By using a BSP model which is based on the concept of a superstep, during which processes perform computations using local data, a more rapid and sensitive program will be allowed.
The BSP package consists of the following components:
Matrix
Graph
Shell/DSL
- Hama DSL (Domain Specific Language) in Groovy – Work in progress
- Hama Shell – Work in progress
