JDWTopGuy's Journal: Blah

Yo yo yo!

I got to (and died on) the 11th level of Descent 1. This in itself is not that astounding, but I did beat the shareware boss (FINALLY!) on level 8.

I currently have a little cluster running, my Athlon, my 166Mhz pentium and my 90Mhz pentium. All crackin' away at RC5-72. I set up my 90Mhz box running the personal proxy, with an automatic dial-and-fetch/flush script that runs at 2:30 AM my time. I also flush my PowerBook G4 thru the personal proxy.

I'm going to write a little script to provide hourly personal proxy stats via finger.

As a side note, I believe my friend is going to send me a 233Mhz pentium chip when he finally sends me my graphics card, so "Cruza" will get a bit faster. It manages about 3 blocks a day right now. I think the 90mhz squeaks out 1 block a day.

Anyway, that's that and all that, you dig?

RC5-72? Gah.

I remember doing RC5-64, and it was kind of fun, but the keyspace for RC5-72 is just so hopeless huge, it seems like a waste of time.

Why not do OGR or seti@home, or even folding@home?

Right now I don't do any, but that's just because my CPU fan's speed is controlled by a temperature sensor sitting underneath the processor, and if I run one of those things, it makes the fan run as fast as possible, all the time, which is very loud and annoying. I'm changing HSF's today, to something that should be more effe

There's a lot of things to take into account before deciding RC5-72 will take too long to be worth it.

1. The G5. RC5-72 screams on a G4/G5. The dual 2Ghz G5 gets around 40 Mkeys/sec, outpacing the heftiest Athlon/P4 systems. The dual 3Ghz (when it comes out) should get 60 Mkeys/sec
2. Faster systems overall... nuff said.
3. Most dnetc users are running OGR because OGR is the default project for a newly-installed client. Once OGR-25 is done, those clients will probably start running RC5-72, which should give

Holy shit :)

So, just to put things into perspective for me, how long does it take you to do a 24 work-unit buffer? My computer does it in 5.5 hours, IIRC.

10 years, ok :)

I just started running RC5-72 again. I stopped doing dnet around the time that RC5-64 was solved, mainly because I installed a HSF that was heat sensitive (ie

Well... my calculations show that if I have both PCs (not counting the p90, it's way too slow) and my PowerBook running RC5-72... about 2 hours, 30 minutes to crunch 24 units, with a maximum of 231 units crunched per day. Actually that's not using exact numbers, so give or take a few units.

I suppose your setup is as much a cluster as mine, the difference with mine is I'm running a personal proxy... it's nice for statsmongering.

I must ask, why would you buy an AXP 2000 and underclock to 1.2Ghz? I'm assumin

Re:RC5-72? Gah.

[JDWTopGuy]

Here's some numbers for comparison: A dual 2Ghz G5 can do around 804 units in a day (that's a dedicated machine), and do a 24-unit buffer in about 43 minutes.

Yet another reason to want one desperately. :-P

I must ask, why would you buy an AXP 2000 and underclock to 1.2Ghz? I'm assuming it's to keep it cool, but man...

It's a long story. Basically, a year ago I bought an AXP 1700, and all the other parts necessary for a computer, and I built it all myself... I knew nothing then, it was loud as hell.

More recently, I bought a computer for my mom. I was too lazy to build one, so I just went looking for the cheapest/oldest/crappiest retail thing I could find (not used), and it was an AXP 2000. So I bought it and
