I believe he mentioned this Steve. Not load balancing, but
scheduling as you point out.<br>
The scheduler does not nail the process to a particular CPU, as is the
case<br>
with other versions of Linux. Support certainly must be there on
the processor<br>
however for SMP.<br><br>
Lets not forget about things such as tag-cache on chip, pre-fetch,<br>
and the like. Little good if your tag cache is on processor 0, and the
process is<br>
scheduled back on cpu 1. But then again, I believe this is built in to
the<br>
Hypertransports, based on some architecture readings<br>
a while back. (memory is 43 y/o now... but I think is correct).<br><br>
Recently my ES 3.0 kernel was updated with the preliminary support
for<br>
the upcoming 2.6 kernel which offers this support. I am preying
this<br>
helps.<br><br>
(BTW, best I could find stock is 248's in a dual AMD package<br>
at $299/mo w/ 2GB ram hosted. The co-lo option is not
reasonable<br>
for me. If I procure the Tyan board, and Processor/memory,<br>
the bandwidth is cost prohibitive. I end up paying more for<br>
the Bandwidth than I do now for the Dual P4 with the bandwidth.<br>
(Looking at the planet, EV1, ServerBeach, Verio, and the sub-slime
;-)<br>
But I am so curious anyway, I just ordered a 2x248 and tyan MB from<br>
newegg.com for my server rack. (It is nice to be santa to
yourself<br>
first. ;-) ) Ironically ServerMatrix does not seem to offer
Fedura<br>
in their offerings. It may be tough to get them to support it
operationally...<br><br>
Now question is Jay, are you talking Fedura Core 1 or Core 2???<br><br>
Thanks for the help. And Thanks for the info Steve. I also did not find
any 448's,<br>
nor 848's, but I could be looking at the wrong places for the
848's...<br><br>
Happy Holidays. And thanks for the help guys.<br><br>

nothing less there ( to my knowledge ). There is no automatic CPU<br>
