=20 Yes, I clearly understand. My point still stands though, if an admin wishes to use power saving techniques for whatever reason, that choice shouldn't deter the rest of us from gaining a more precise accountability for our CPU cycles. Thus why I suggested a blurb be added with this patch stating the ramifications of using power saving techniques with this method of cycle sampling. =20 -----Original Message----- From: Garance A Drosihn [mailto:drosih@rpi.edu] Sent: Friday, January 27, 2006 1:02 PM To: Mullen, Adam Cc: arch@freebsd.org; freebsd-current@freebsd.org Subject: RE: [TEST/REVIEW] CPU accounting patches At 12:39 PM -0600 1/27/06, Mullen, Adam wrote: >Lets see here though, how many of us have a 100 node beowulf cluster=20 >who use FreeBSD daily? I know I don't! That isn't the question I am answering. The question was "Who in their right mind users power saving features on a server OS?". And the answer is "People who run LOTS of servers". That is all. I'm not saying *you* have to run power-saving features. I am saying that there are people who use a SERVER operating system, and who have very good ($$$$$$$$$$$$$$$$) reasons to care about power consumption. People who on the one hand do want infinite CPU power, but still have to balance that desire with the monthly bill for energy and cooling. --=20 Garance Alistair Drosehn =3D gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu This message contains confidential information and is intended only for t= he individual named.
