There are often ways to exploit parallelization to make things go faster. Some tasks are easier than others, and sometimes these things are completely non-obvious, or even attainable only outside the scope of R or only to those with extreme expertise in obscure things (ie. using (or writing!) a multithreaded blas library, for example). Without knowing the details of A, B, and C, you have no hope of getting a useful answer -- or even a hint for a useful answer, but I'll answer your question all the same: "Yes, it is possible". You'll have to provide more details in order to get any useful help. Note that there is also a "high performance computing" with R mailing list that might also be helpful. https://stat.ethz.ch/mailman/listinfo/r-sig-hpc -steve -- Steve Lianoglou Computational Biologist Bioinformatics and Computational Biology Genentech _______________________________________________ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
