this is quite an interesting read. it talks about the entry level i5 and
compares them to the i7s. granted its comparing the 2 you will learn alot
about the i7s as well.

3) Be aware that the kernel you are using will make a big
difference and that the semantics for ext3 have changed
a while ago so that it no longer uses data=ordered but
instead uses data=writeback by default (you can override

A couple of things to bear in mind..

Yes, that's fine, there are 2 reasons to stick with

However, our own benchmarking using nbench, unixbench, and a home-grown
utility (twobod) all show that any differences are attributed to clock speed.
do you have any sense for whether these are entirely in-cache benchmarks?
that's the most obvious explanation. nehalem is all about the new memor
Do you have SOL on the HP DL145-G2 ?
to be honest, I've never tried it. our machines came with HP's XC distro,
which includes a console logging/terminal command. it appears to use the
telnet interface, though, not ipmi sol.
I also have these nodes, and although I can use most ipmi function

Check out the Duke Marine Lab website. They basically do this, via

To use seawater to cool a room safely it would have to be well isolated,
exchanging heat with a loop of much more innocuous fluid that actually
enters the room.
Dave, I really think that is how you would do it. I was a bit loose in
terminology.
