Of course this is the right group. MOSIX adopts certain techniques for providing distributed services, say processes, etc. In general, however note that you might go for HA quite easily but in many cases HPC will be very hard to attain on any system that is just POSIX. What I mean is PVM or MPI programs usually take good advantage of the parallel machine, while a distributed OS can't do that very good on its own without help from programmer about parallelism) > > And maybe one more question, more suited for this group - what do you > think about moving statistical computation to hmm let's say pvm enabled > set of machines ( now it's beeing done on 2*sparc 350, quite fast, but > 12*pII sth should outperform it) > Do it on MPI, you need a paper or two about HMM computation in parallel probably.
