Sean, I've succeeded at running ECJ experiments in parallel over a DRM network. This work can be useful for someone and I'd like share it, could I upload my ec.drm package to your servers? Right now the behaviour it's pre-alpha, but I'll continue working on this for some time, don't worry (I'm being paid for it, actually). I hope to have a tutorial for it next week. For the people who doesn't know what DRM is, here goes a little explanation: The DRM (Distributed Resource Machine, nothing to do with Digital Rights Management) was developed a pair of years ago by Mark Jelasity between others. It aims to be a p2p network for running java experiments. An evolutionary computation library (JEO) was developed for it, and both were distributed together as the DREAM project. More information can be found in http://sourceforge.net/projects/dr-ea-m. Since then the project has come mostly unmantained, although used in some research groups. The DRM concept was a good idea, being an easy way to use a large group of different computers to solve a large experiment. Given the superiority of ECJ over JEO I was assigned the task to make ECJ experiments run over the p2p DRM network. Also I'll have to make many improvements in the DRM behaviour. Cheers, Alberto
