boulabiar: hi all
boulabiar: Someone knows what's the company that has a similar logo to the X.org one ?
Space_Man: Apple, Xerox
boulabiar: Space_Man: no, the company they cited
skyhirider: anyone here is a guru at networking or knows a good irc channel for such stuff?
djura-san: howdy o/
RambJoe: how many cpu cores can linux support
mjr: more than you have
RambJoe: ah just saw 512
RambJoe: doesn't say the max ammount of gpus though
RambJoe: http://en.wikipedia.org/wiki/Cray_XT5
RambJoe: how do they have over 200,000 cores
RambJoe: did they modify the kernel
s_20: it was an easy patch, they changed #define MAX_CPUS 512 to #define MAX_CPUS GAZILLION
RambJoe: ohhh
RambJoe: why is the limit there :S
RambJoe: what file is that in
markatto: I don't think that the Cray supercomputers are of the shared-memory variety
markatto: I could be wrong
markatto: with a message-passing supercomputer, the number of cores that the kernel can support is pretty much irrelevant
Gnurdux: RambJoe, Linux per se doesnt really know or care about GPUs
Gnurdux: you can have as many or as few as your drivers can handle
RambJoe: oh
RambJoe: http://cateee.net/lkddb/web-lkddb/NR_CPUS.html
RambJoe: why is the maximum different on the Kconfig.cputype one :S
RambJoe: oh i see if you enable max smp you can have 4096 cores
