Detailed Description

An predictor of the communication execution time. Contains a set of the predict functions:

• double (*predict_p2p)(void* _this, int i, int j, int M) is a function predicting the execution time of the point-to-point communication operation, where i and j are the indices of the processors, M is a message size.
• double (*predict_Y)(void* _this, int M, int root, int size) is a function predicting the execution time of the algorithm of collective communication operation Y (for example, Scatter_binomial). The root parameter is significant for the collective operations with the root processor.

Each of the estimation functions includes a self pointer argument _this to be used in the derived data structures (communication performance models).
