How to organize distributed integration testing?

Question

Distributed Computing

There is an application in C++ for Windows OS. It can be run with arguments and pass a script file there, where the actions for the test are recorded. After the test, report files are generated from different application subsystems. These reports are compared with benchmarks. There are quite a lot of tests and I would like to organize a parallel launch of tests on computers in a local grid with little bloodshed. Are there any simple solutions?
