[gentoo-user] SMP not working?
actually the SMP is working, as in top shows 2 CPU's. but when i do an emerge --sync CPU1 stays pegged at 99% and CPU0 stays below 1% the entire time. this is a dual 200mhz U2 Sparc system, i was just wondering if this was normal or is there something messed up in my config? and sorry for posting this in the normal user list, i figured i would get more responses here as i dont think this is specific to Sparc hardware, but i could be wrong.

Checked it out on one of my dual servers. There is never more than a single process running, emerge, then rsync, then emerge, so the second CPU never gets used. However I did see the second CPU doing some kjournald while data was being written to the filessytem so it's not a total loss on a dual CPU system. :) kashani -- gentoo-user@gentoo.org mailing list

AFAIK, certain operations can't use both CPU's because of the way they're written. rsync (used by emerge --sync) may be one. At least you'll use one cpu for rsync, and the other cpu for everything else you may be doing at the time, so you'll still get a performance advantage. and sorry for posting this in the normal user list, i figured i would get more responses here as i dont think this is specific to Sparc hardware, but i could be wrong. No worries! I don't know what the official word is, but this list is more a general usage list, rather than gentoo specific issues. -- Iain Buchanan iain at netspace dot net dot au How come financial advisors never seem to be as wealthy as they claim they'll make you? -- gentoo-user@gentoo.org mailing list
