It is counted from zero, kthx.
rpm -q kernel-default kernel-default-2.6.22.2-ccj52
Any idea what is happening? I have Core 2 Duo

You also have a processor "0". Try just cat /proc/cpuinfo | grep ^processor -- Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
openSUSE bigsmp kernel supports up to 32 x86 processors. AFAIK you can build custom kernel with support of up to 255 x86 processors. -- -Alexey Eremenko "Technologov" -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

SLES 10 supports up to 1024 cores _out of the box_ on SGI Altix servers (NUMA systems aka SSI, _not_ clusters). Rafa -- "We cannot treat computers as Humans.

And there is hardly room for expansion. Your Altix 4700 already comes with 512 cores... Jan -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

And it scales upto 1024 cores and 128 TeraBytes of RAM in a SSI (one kernel running). NOT a cluster ;) Rafa -- "We cannot treat computers as Humans.

That is the largest machine around, I suppose the guys from SGI have some with even more.
SGI, HP, IBM, and Red Hat all are testing with many CPUs. I think the more important issue is scaling. I couldn't quickly find any recent articles, but tests have shown Linux to scale well at 64 CPUs. I suspect that you could probably find a paper on the SGI, HP, or IBM sites that shows scaling data for more than 64. Currently, I can't afford a 64-CPU system :-) -- Jerry Feldman <gaf@blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9

That sounds like a tongue twister... how much wood would a woodchuck chuck if a woodchuck could chuck wood? http://www.linuxdevices.com/news/NS6099969220.html AFAIK, this says the thing has like 60 cores. I've seen articles where systems have 140+ cores. So you gonna hop down to Fry's and pick up a 140-core motherboard?
