IPME and External Clients: Enhancing Performance by Offloading Simulation Workload to External Clients; Explaining and Simplifying the Process.

摘要

The speed of simulation execution as performed by the Integrated Performance Modelling Environment (IPME) degrades significantly when computationally demanding functions, such as iterative mathematical calculations, are included in a model. Much of this degradation can be mitigated by transferring those functions that require significant computational resources (cpu processing) to an external client using the external client architecture that accompanies IPME. This client communicates with IPME using TCP/IP network protocol, exchanging values of common variables over the network. Using an external client allows more processing power to be dedicated to computationally expensive tasks and are generally more robust to increases in computational demand. A computationally demanding sample client is used to show the execution performance differences when the procedure resides within the IPME task network and when it is offloaded to an external client. This report also outlines how to use the sample client source code to build a client program, extending the developer's approach for client program development to create a more flexible interface. This will provide another option for client developers who may prefer a more intuitive template for developing their customized client than the sample client provided with IPME.
