Correct on both

Correct on both points.

Speed selection is supposed to be coming. If you look at your contact logs, you'll see the scheduler still collects data about and differentiates between slow and fast hosts. However, due to the nature of the S5RI run it wasn't necessary since they were all roughly the same (or so it seemed).

What's concerning me is the run times we're seeing currently, and I haven't seen a WU yet over the S5R1 breakpoint of 400MHz between short and long. Assuming that pattern holds and they ultimately speed up the app by a factor of 2 this would still leave EAH a much tighter deadline project than it ever has been before. As most of us here know, tight deadlines don't play very well with any kind of significant work cache without having to resort to EDF mode and force the CC to diverge from your resource share in the short term.

Given that 5.10 will introduce a preference option which will essentially allow a participant to partially override the CC scheduler's ability assure work is done on time, tight deadlines will be more of a problem and the main one will become missed deadlines for some work which gets 'rammed' down the hosts throat.

Wouldn't it be funny if my host was considered a "fast host" if they implemented this before application optimization? I guess technically my host is a faster host, but not actually fast...

Well, that's always very relative :-) I remember a discussion here if a P3 Coppermine at 666 MHz would actually be considered a "fast host"...

Well, according to the

Well, according to the contact log it's classified as a slow host. IIRC, when we talking about it before the question boiled down to would late Katmai and early Coppermines be capable of running a long result and make a two week deadline on S5R1.

I'm pretty sure my 550 Katmai could running 24/7, and I'm reasonably sure your Coppermine would and even have some leeway to play with.

Like I said then, there ain't much wrong with the PIII, no matter what flavor they are. ;-)

Yep, that's true. They

Yep, that's true. They certainly have a good architecture, which you can see from the fact that they based the Cores, Core2s and most of the mobile CPUs on it.
Problem is, mine here is not nearly a 24/7 host... well, we'll see.

If it's an Einstein-Only box,

If it's an Einstein-Only box, it would be a good
idea to switch to Linux. The latest performance
problems seem not to affect Linux on coppermines
too much :-)

p.s.: maybe I should reactivate my Katmai 550 too,
it's still fully functional, no parts stripped ;-)

p.p.s.:

my P3/600 (Linux) does a 156 credits WU in 116571 seconds,
a Celeron4/2800 with XP (no HT) needs about half the time

I would have switched to

I would have switched to Linux ages ago if it really was "my" box. Unfortunately it isn't. It's my Dad's, he just let install BOINC on it (and fix everything he breaks, so I know this box quite well...) He considered switching to Linux himself, though, but he has no Linux experiences whatsoever. I wonder if the latest KUbuntu might be a good way to start...

I don't have any Linux experience and have been chewing on the idea for awhile now. I'd like to perhaps partion my drive and be able to boot to either Windows or Linux. I'd like a suggestion or two on a Linux flavor to go with for beginners. Something that won't have me fuming while sitting in front of the box because I'm used to having my hand held by Windows (devil inside,lol). Thanks for any suggestions that anyone would offer.

If you load a SuSE Linux on a partition, it won't cancel your Wimdows partition and the Grub boot loader will allow you to boot Windows if you wish. I am using SuSE 10.1 but there is already a 10.2 release. You can download it all on 5 CDs or a single DVD, also using a BitTorrent client. I use Azureus.

Yep, I often dual-boot my boxes, too (meaning I'm running both Windows and Linux on them). It's usually no problem to set up, just install Windows first, then Linux, and the bootloader will take care of the rest.
As for the OS choice... I'm not really a fan of SuSE. Okay, it's supposed to be good for beginners, but in this case that also includes it's a bit more difficult to change to another distro. Besides, I fear that SuSE is not really "free" any more after Novell's deal with Microsoft.
As I said, maybe you should try KUbuntu. It's based on Debian, but it already has lots of useful stuff pre-installed and most of the configuration done, plus a really nice GUI.
This is of course just my personal preference and experience. If you're not sure, just get a live-cd (a CD you can boot the OS from directly) from each distro you might want to try and play around with them a bit until you know which one you prefer.
