I've used dual-processor machines for about 10 years now and emphatically second the point made by Brian Ripley. Even if you are not running several R jobs at once, it is nice to do something else at full speed while a simulation uses another processor. Often overlooked is the additional large advantage to be gained by using SCSI disks rather than any form of ATA. With today's large applications and operating systems, there can be frequent paging, and a SCSI subsystem will make a large difference in computer response, at least under Windows. Unless your work is processor bound, disk I/O is usually what sets the pace. -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
