Abstract
Performance of the Integrated Performance Modeling Environment (IPME) degrades significantly when computationally demanding functions are included in a model. Much of this degradation can be mitigated by transferring the resource intensive functionality 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 the computationally expensive task. It is also more robust to increases in the demands on these tasks. 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.
