I don't think R is immediately relevant to the question here. The Atlas docs are pretty clear that Atlas will run multi-threaded, using up to N cores, IFF it is compiled to do so. The limit N is set at compile time: http://math-atlas.sourceforge.net/faq.html#tnum On my dual-core laptop running Ubuntu 9.04, the libatlas-test programs also run using only one core. So, I doubt this has anything to do with R, most likely the Ubuntu Atlas packages are built to use one thread only. To figure it out, you should look into how and why the Ubuntu Atlas packages are compiled exactly, perhaps comparing to the stock Atlas build instructions. -- Andrew Piskorski <[email protected]> http://www.piskorski.com/ _______________________________________________ R-SIG-Debian mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-debian
