DES Keyrate Rapidly Growing

writes "As you probably know the EFF's Deep Crack machine
which won the last DES challenge is working with
distributed.net for this contest. There's
a graph
which shows the performance of deep crack (labelled DC)
and the rest of the distributed.net effort (labelled DCTI)
which is composed of everyone running the rc5des clients.
The keyrate from the combined rc5des clients is double
that of Deep Crack compared to that of last time when it
was less than Deep Crack (which has a constant keyrate).
The combined rc5des + deep crack keyrate is also shown."
Also, Team Slashdot is #2 in
the top 100 if you're curious.
You can get live stats on irc. efnet #deskeyrate
This is sort of off subject, but as I was perusing the list of teams, I came across one name that made me chuckle.
Fighting Force of Extraordinary Magnitude.
I believe that this phrase is taken from the great flick, "Kentucky Fried Movie." Directed by John Landis, and written by the Zuckerman (?) brothers, KFM was a classic when it came out 25 yrs ago. Catholic High School Girls in Trouble, Fist Full of Yen (no, no, not Detroit), and other vignettes. Absolutely no social redeeming value! If you are a guy, DO NOT watch this with your girlfriend or wife.:-)
BTW, Deep Crack is pretty amazing.
Ever since DES-III started, my Linux client has had trouble switching over. It took it quite a while to just pull some DES blocks from my proxy server, but I got that much working eventually. Now, in just over a day, it's cracked through one block. It just refuses to do anything else. That one block came some 3 and a half hours of running. I let it go overnight and it hasn't done a thing.
It's unfortunate, but my Win98 box is churning through these puppies in like 15 minutes each. I tried my older client, as well as the newest they had with the same results.
Anyone else had troubles? It'll probably be over before I can find anything...
happened to me once too. turned out I had some zombie process eating away 98% cpu time...
It seems the speed has been brought up quite a bit, I have my machine set to cache 30 blocks, (about 16 hours work usually) went offline to sleep, came back to find it completed all the DES blocks, and did two RC5 blocks as well!
Not that my rate is that high (1.9Mkeys/sec) but it's only a P166/MMX.
Did anyone get a look at this team's webpage? It's pretty funny...

Hey! Just got this message..I suppose they found the winning code?

That would be very lucky, after trying only
28% of the available keyspace!

You are definitely doing something wrong. I have the same processor, and under Linux it gets around 2.5Mkeys/sec! Maybe rc5 client is not getting scheduled because of something else running.
Something my UltraSPARC systems can crunch on... my Ultra 5 managed 4.4m keys/sec even while I work on it and play MP3s in the background, et al.
:(
So frustrating that the RC5 is inefficient on SPARC systems
...Steve
if those numbers are right we should exoust the
key space in about 5 days
The most striking thing for me is the poor showing of Team EvangeList. My theory - the lack of a quick-switch client for the Mac meant a lag of several hours before most people started crunching DES blocks. It took me three hours before I remembered to force a switch.
I think I'm going to throw in the towel on distributed.net after this, at least until they switch to OGR or Mersenne primes or whatever the new plan is. RC5-64 - who cares? It's just infinite monkeys typing and getting it sooner or later. I can't get myself worked up over SETI either.
What I'm listening to now on Pandora...
If you subtract out Deep Crack's (toad.com) numbers from the #1 team, we're the fastest software-based team.
Plus, I joined Team Slashdot just now (with keys already submitted) because it hasn't been possible to join a team for most of the past 3 weeks while the DES-TESTs were running.
Software sucks. Open Source sucks less.
Hmmm... maybe so... :)
fetch and flush on my clients... now they're crunching RC5.
83 Ultra 10's will do that, I guess :)
oh well, back to work.

Run top for a second and kill the process that's eating up your cpu. Don't leave top running though, it's a cpu hog too.
Who are they? Where did they come from? And , most importantly, how the hell did they scrape up three times our kkeys/sec?
Aren't you dead?
Great, people I know were already saying that
d.net wouldn't make it against Tha Big One, but
now there seems to be a chance !
