I'm trying to get my head around the concept of using Wolfram's gridMathematica in a compute farm setting. The Mathematica product allows one to launch "mathlink kernels" on remote unix or windows hosts. They are quite proud of how standalone and independent the product is (all it needs is a tcp connection). heh. I'm tring to bring the product into the fold so to speak with other cluster-aware applications that use the cluster resource management and batch scheduling subsystems. Single host use within a compute farm is easy. It's trivial to bsub or qsub an interactive request for 'math' and run a single mathematica kernel on a fast remote machine. Now I want to run against N mathematica kernels speaking via mathlink to each other. The eventual goal is tight integration within LSF and SGE but right now I'll be happy with a loose "get the hostnames from the batch scheduler and feed those into a mathematica notebook or shell script that will then launch the mathlink kernels" sort of way. Has anyone done this? Also- I'm a complete idiot when it comes to math. Are there any mathematica users out there who can share a test/demo computation that actually makes use of functions like ParallelMap and ParallelTable? Regards, Chris
