RemoteInstance
Launching a PrajnaInstance on a group of remote nodes. serviceName: name of the serivce param: parameter to be called by OnStart serviceInstance: OnStart(param), OnStop(), Run(), IsRunning() call for the initiating of the service. You must derive serviceInstance from WorkerRoleInstance PrajnaInstance share similar characteristics with Prajnaservice, with characteristics below. 1. You can run Service on Azure VM or your own cluster in the data center. 2. You can host multiple worker role in a same remote program. 3. Service can interact (call each other) with each call being a function call. 4. You can perform Big data analytical tasks (map/filter/choose/collect, fold, map-reduce, sort, hash-join, cross-join, etc.) on data generated by Service 5. You can start Service with a parameter. 6. You can track debug output (log, stderr, stdout) of the remote service. But in addition, PrajnaInstance is 1. Initialied remotely (with a function that you have specified). As such, PrajnaInstance doesn't need to be serializable, and can contain heavy data element. 2. You may specify the number of thread to work on the PrajnaInstance (parameter specified in Start Parameter.
