Howdy list, I have a few questions about FreeBSD's in-progress SMPng project. I've read much of the literature on the FreeBSD site about SMPng, and I've taken the time to go through the project status pages and look at the work that has already been done and the work yet to be done here: http://www.freebsd.org/smp/index.html http://www.freebsd.org/projects/busdma/index.html But I'm still unclear about a few things: 1.) What, exactly, are SMPng's advantages over the current SMP implementation as related to userland apps? In other words, I know that the network stack and devices and such will benefit by being able to make use of multiple CPUs, but will normal non-multi-threaded apps be able to use multiple CPUs? Or will an app still have to be multi-threaded in order to take full advantage of an SMP box? 2.) And, perhaps as an extension to question #1: Will I be able to make use of multiple CPUs to compile programs? Could I buy one of those cheap $300 quad Xeon 500mhz compaq boxes on ebay and use it as a 2 Ghz compiler box? Thanks! -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
