Running UD with 16meg of ram..

Well, my second system used to run Gamma Flux, it's an old Atrend 5000 motherboard with an AMD K6 at 200mhz, 16meg of EDO ram and a 40meg HD running win998fe. I recently was given an old Quantum 270mb HD, and though that it may give me the space needed to get enough of windoze on it to run the Think client. Didn't need much of windoze to run Gamma Flux. It took about 20 hours and many media wipes/fdisks/formats to find out that win98fe must instal with HD UDMA enabled or something, cause after about the second instal reboot it would keep hitting the drive and go nowhere during the setup phase. Finally tried win98se, and it went in. I attribute the problem to the UDMA thing cause when I enabled it in windoze and rebooted I was back to square one again. Ovious to me now that the old Quantum is definately not UDMA compatible! Thier web site only provided me with pinouts and CHS values. Won't enable that again! Despite UD's client complaining that it required 48meg of ram, it installed anyway, warning me that it may not work at all. I expected it to choke or make smoke, but amazingly enuff not the case! It started up and downloaded the required files and to my surprise it started doin it's thing, and I still have 32meg of HD spae too play with after all this, fat16 not campressed. To summarize, it's now running on windoze98 Second Attempt, Atrend 5000 motherboard, 16mb of old EDO ram, an AMD K6 at 200mhz, old 6x Acer cdrom, Matrox Millenium PCI video card, old Radicom ISA 28.8 VFD modem, very old monitor of unknown origin at 800x600 resolution, and oh yeah, a logitech two button mouse. Needless to say, my system doesn't score very high, and I'm not expecting it to finish this work unit any time soon. Performance rating on this first work unit are as follows..
Processor = 14
Memory = 5
Storage = 6
Network = 8
Overall = 9
And you think you had some low performance ratings?
Oddly enuff I expected the swap file to take a kick in the nutz, but after the client starts all is quite, or as quite as it can be, that old Quantum has to be the noisier than my 25 year old fridge, it just howls. There's not much else installed, however I can browse the C: with explorer without a lockup. Makes me wonder about all the posts I have read on UD forums by people cranked off cause thier fancy high grade systems crash 10 times a day. I think a good part of why it runs is the use of Cacheman 4.0. Windoze doesn't handle its virtual disk cache very well, this will help straighten it out for you. Oops! Just checked their page and now there's a 4.1. It's freeware at http://www.outertech.com/. Darn, wish I'd checked that before I installed it. Installing the new version and using the "low memory" preset helped even more, with UD running I have a 35meg swap file, down consisderably from using v4.0, probly due to the new "unload dll" function enabled. So, if you have an old machine sitting in the closet collecting dust, it may be worth a try, all you have to lose is the time it takes to set it up. If you are installing windows to a small drive and it complains about not enuff drive space, try using - D:\setup /id - (where D: is your cdrom) to get windoze started, that tells it not to check for available disk space. You will likely need at least 250mb drive, and have to custom setup with minimum goodies.
Dedicated to Distributed Computing? Nah, not me. Actually, making win98fe run Gamma Flux on the 40meg HD was more of a challenge, it would go for weeks without a crash, usually it was a power dump that made it reboot. Being really bored helps to. After 5 hours 4min running, it's done 9 percent with three hits, and still hummin' along.
Happy CPU warming, with whatever you like to use to keep it warm with! :D

Geez... Sled Dog - you need to ditch the winblows and get Linux on that baby... Then you won't have to worry about rebooting ever again... ;)
(As for my "older" machines, I'm running Linux on a 486 DX4/100 w/32MB RAM, P120 Thinkpad w/40MB RAM, and a P200MMX w/24MB RAM).

Let me just say this - it took me over 2 days on a K6-2/500 to complete the particular UD WU I was running. Granted, it had the screensaver running and I've since turned it off... But I can imagine how long it would take on your hardware... ;)

Your 98 install would probably need a pretty good sized pagefile.sys and paging is what will probably really slow it down. There's no equivalent to a text/commandline client for this program yet...

Why not run OGR on it? Seems the ProcessTree take-over of DCypher.net has pretty much screwed the whole project... :|

In fact, I saw a post yesterday on UD's forums that it appears that ProcessTree is rapidly heading for or is in bankruptcy... :(

TA could use some help with OGR or even RC5... :)

[EDIT: I forgot - there are 2 other projects that have small teams for TA going - Folding@Home and Genome@Home. You could check out Waterhouse's thread for some info on that. :)]

Ya, but where would the challenge be in that? Actually, I tried Linux once, got totally lost right of the bat. Don't know anyone with linux experience to get a hand with it, besides I thought UD was kinda neat, I'll give it a try for awhile. Surprisingly enuff, I been sitting here for the last few hours and the drive has only spun up twice, maybe to save its work. Anyway, I think I need some sleep, between getting that machine going and reloading a friends machine (486dx or sx, can't remember, 90mhz, 16meg ram, 98se) I been up for 21 hours. I'll let ya'll know if it makes smoke or work units. :D;)
