grape::ParallelAppBase< FRAG_T, CONTEXT_T, MESSAGE_MANAGER_T > Class Template Reference

ParallelAppBase is a base class for parallel apps. Users can process messages in a more flexible way in this kind of app. It contains an ParallelMessageManager to process messages, which enables send/receive messages during computation. This strategy improves performance by overlapping the communication time and the evaluation time. More...

Detailed Description

template<typename FRAG_T, typename CONTEXT_T, typename MESSAGE_MANAGER_T = ParallelMessageManager>
class grape::ParallelAppBase< FRAG_T, CONTEXT_T, MESSAGE_MANAGER_T >

ParallelAppBase is a base class for parallel apps. Users can process messages in a more flexible way in this kind of app. It contains an ParallelMessageManager to process messages, which enables send/receive messages during computation. This strategy improves performance by overlapping the communication time and the evaluation time.

Template Parameters

FRAG_T
CONTEXT_T

Member Function Documentation

IncEval()

template<typename FRAG_T , typename CONTEXT_T , typename MESSAGE_MANAGER_T = ParallelMessageManager>

virtual void grape::ParallelAppBase< FRAG_T, CONTEXT_T, MESSAGE_MANAGER_T >::IncEval ( const FRAG_T &  graph, CONTEXT_T &  context, message_manager_t &  messages  )

pure virtual

Incremental evaluation to implement.

Note

: This pure virtual function works as an interface, instructing users to implement in the specific app. The IncEval in the inherited apps would be invoked directly, not via virtual functions.

Parameters

graph
context
messages

PEval()

template<typename FRAG_T , typename CONTEXT_T , typename MESSAGE_MANAGER_T = ParallelMessageManager>

virtual void grape::ParallelAppBase< FRAG_T, CONTEXT_T, MESSAGE_MANAGER_T >::PEval ( const FRAG_T &  graph, CONTEXT_T &  context, message_manager_t &  messages  )

pure virtual

Partial evaluation to implement.

Note

: This pure virtual function works as an interface, instructing users to implement in the specific app. The PEval in the inherited apps would be invoked directly, not via virtual functions.

Parameters

graph
context
messages
