Abstract:In order to explore and demonstrate the advantage of TIPC in communication between processes, the TIPC was briefly introduced first, then the communication performance of TCP and TIPC was measured in full-scale. In the same time, detailed analysis was applied to the measurement data. The result got here could instruct the message package size choosing in parallel program. what’s more, the data got also indicate that the TIPC could get higher bandwidth than TCP. In this way Parallel program can be optimized and efficiency improved with communication in TIPC way.
