Hello Neil, Congratulation for the installation of your clusters and few remarks (sorry if i cut some text)...

For the debian test, i will be happy to have your feedback, the website is http://oscarondebian.gforge.inria.fr/. The project cannot be used in production but i am definitively interested in users feedback and of course by contributions. Actually i am still working on the integration of OOD into OSCAR trunk but a lot of stuff still have to be done. Therefore if you want to contribute (even for simple tasks), just let me know. :-) > > lastly > there was a question a week or so again about benchmarking > the answer was that it depends on the intended use. fair enough. > I was thinking that there still must be something more generic that > could help if one wanted to know what improvements (or not) if one say > moved from a hub to a switch, or added memory to the compute nodes, > or doubled the number of nodes > my example would be if i joined some of my 8 test nodes into the main > 'production' setup. > what woud i gain 'in theory' for my application. > any ideas ? I think there are two different points: benchmarking and application gains. For application gains, it depends on your application. If the application is designed to scale up to the new size of your cluster, you should have a speed up. At the end this is the old problem of parallelism. :-) For benchmarking this is another question. Benchmarks is based on well-known algorithms which are often design to scale and take a full benefit of cluster resources. But that does not mean your applications will have the same behavior (it depends on your applications again). Anyway, there are no benchmarks (for what i know) shipped with OSCAR. I think about it since a while but i did not have the time to work on that. If i am not clear or if you want more details, feel free to contact me.
