Detailed Description
template<class leftHandlerType, class rightHandlerType>
class InputDataHandler< leftHandlerType, rightHandlerType >
A very thin wrapper class.
Instantiated as a chare array that provides GSpace chares with an API to send the input data in. The intent is to permit a somewhat generic message handling behavior that doesnt require GSpace to jump through hoops.
Currently it is desired to collate messages and compute on them later. Requirements might change later to require streamed computing etc which can be met by configuring this class with different message handlers.
This is a template class only so that it does not have to pay the penalties associated with using base class pointers. The left and right message handlers could simply have been pointers to a base class MessageHandler. However, this would involve virtual function call overhead and would almost certainly prevent inlining of the handlers' operator(). To avoid this and yet retain the ability to support new behavior at a later date, this has been made a template class. This should provide a relatively stable API for the GSpace chares to use, and all this template muck is only compile time overhead anyway.
- Note
- : Behavior expected of handlerType classes:
- void handlerType::operator() (paircalcInputMsg *msg) : Used to pass in the messages for processing
- void handlerType::setupRDMA(RDMASetupRequestMsg<RDMApair_GSP_PC> *msg,RDMApair_GSP_PC *tkn) : Used to pass on a RDMA setup request from a sender

Entry Method. An instance needs to be configured with the actual message handlers.
Get a handle on your customer PairCalc chare array element
If your customer is on this same processor (which it MUST be) Ask it for pointers to the message handlers
