No, it would be of use. The approach is to run multiple independent processes -- this is the general "message-passing" paradigm, and holds true regardless of the particular API being used. So each R process has to be appropriately initialized. SNOW is taking care of the RNG, but you've got to do everything else. > So, the question would be how to get the R slaves to load up the library > and I don't see any obvious way of doing this (using snow functions). > > I must be missing something. Do I need to work at a lower level? Yes, and no. Re-read the CPH-statcomp lab, and look at the bootstrap example, which solves the same problem. Look carefully -- it has to initialize the library on each node. If you are just loading the library manually, just do it on each node; if you are using libraries, just do that. best, -tony -- [EMAIL PROTECTED] http://www.analytics.washington.edu/ Biomedical and Health Informatics University of Washington Biostatistics, SCHARP/HVTN Fred Hutchinson Cancer Research Center UW (Tu/Th/F): 206-616-7630 FAX=206-543-3461 | Voicemail is unreliable FHCRC (M/W): 206-667-7025 FAX=206-667-4812 | use Email CONFIDENTIALITY NOTICE: This e-mail message and any attachme...{{dropped}} ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
