Dear fdmanana, Thanks for your interest. > Is this a good feature to start with?
Yes, I think so. BTW, you need to wait few days for this. The reason is that the number of supersteps should be counted by the master server but I'm heavily touching code of master/slave server for HAMA-276 now. Moreover, there is a lot of hard coded path and TODO things. However, It is OK to contribute only part of superstep counting. Please see the part of BSPPeer.enterbarrier() method and heartbeat messages between the master/slave servers. ---- And, let me explain more detail about the current status of HAMA TRUNK .... When user submits a BSP job, the mechanism is almost same with the M/R framework. The basic flow is as below: 1) User submits a BSP job to Hama BSP cluster. 2) Then, the BSPMaster will manage jobs that user have submitted to the BSP cluster. 2-1) Adding job to the scheduler. 2-2) Assign Task to slaves. 3) the GroomServer (slave) copies job/jar file to local and launches tasks on its host. And, Hadoop RPC will be used for the BSP send, get and sync communication among BSPPeer. Now the no. 3) is not implemented yet. Thanks.
