RC5-72 vs. ECC2-109?

Which one do I want to be working on?
I'm half Polish, so I gotta see a POTENTIAL of a payout for all this electricity I'm burning (especially in the SUMMER when I can't say all that heat is helping the furnace out!). Of course, the odds are astronomical, but it helps the Polock in me justify the geek in me's actions...
Anyways, I'm not sure about the size of the keyspaces of the two contests, but the fact that ECC2 selects randomly seems inefficient.
I've got mostly P3-based (including Celeron) crunchers, as well as a few other hangers-on.

So, which one will I be more successful at?

Thanks for the input,
Don
 
ecc2-109 is a much smaller project, with a lot smaller "keyspace"

I've heard rc5-72 will many take many, many, many years at it's current rate..... I dont think ecc2 will take nearly as long

hopefully someone will jump in with their estimate of rc5-72's project length

also, my mini-team is the highest ranked user on team anandtech for ecc2, and we dont really have all that much power going for us.... anyone at all can definately make a difference 😛
my mini-team would much rather be second place, or third place, etc under superior crunchers, because it would only benefit the team 😛
 
I'd say go with ECC2-109 all the way. RC5-72 is estimated to take somewhere around the order of 1.8 millennia (that's 685,345 freaking days, people!). Since there's almost no chance it will be complete before my great-grandkids die (if I would ever have any, I'm 16 now, FWIW), it doesn't provide a lot of motivation to participate. The only reason I'm running it on my "work" computer is that it has the easiest, smallest, and most configurable client available, and said client gets by just fine on once-a-week dialup connections at 14.4K (SETI could handle the infrequency of connections, but the huge WUs would be a PITA on 14.4).
 
According to dnet's overall project stats page it should take about 1,876 years (that's including all those leap years) to fininsh RC5-72 at yesterday's keyrate. That's not taking into acount that machines are getting faster, and there has been a general lack of interest in the project.

Dnet has finally gotten their act together when it comes to stats. They're usually out an hour after 00:00 UTC. Plus the client is one of the most stable and configurable ones I've ever had the pleasure of dealing with. It can be run hidden and as a service. The personal proxy software for feeding large herds of machines is simple to set up. The personal proxy stats on the other hand can be a royal pain in the arse to figure out, unless you're a *nix guru.

I personally don't care if I'm around to see the end of this contest. I've got all the machines I can get my hands on working for me and I'm still only doing around 850 blocks per day. In my hay day of RC5-64 I was putting out over 20,000 blocks per day. I still think the client isn't fully optimized for certain processor cores right now, but it can only get better! 😀

Do what ever project you want to do!
 
Well, if you go by strictly your odds of winning money, then simply put run ECC2 first, and RC5-72 when ECC2 finishes. There is > 50% probability that ECC2 will be over by November 2003. There is very little chance of RC5 finding the solution in that time frame. Also, the number of users participating in ECC2 is less than RC5, so that also increases your odds of being the one to find a solution. Furthermore, there are two 'winners' in ECC2, as opposed to one in RC5, and the payment to the winners in ECC2 is 2.5x that of the winner in RC5.

The way points are calculated is not truly random in ECC2. It just uses an algorithm based upon the birthday paradox, and actually is more efficient in general than a brute force attack like RC5. There are, of course, many other non-financial reasons to run or not run a given DC project.

Hey, thanks for the input, guys! I'm sure I coulda found all that good info somewhere... ???
I'll just keep cranking away! 🙂

Odd.. just checking the stats, I see a MereMortal has overtaken our miniteam.. yay! 😀 😉

Glad to see ya up there doc 😛
 
I've had this problem, but it only happend a few times. Here is what i did:

Upgraded PS
Upgraded to newest bios (cheepoman hacked one found at OCWorkbench)
Took off Northbirdge heatsink, cleaned it and the chip under it, put back on with atrci silver adhesive

No more cold boot probs to date. Which one fixed it? My guess was the PS. I was running a cheap 300watt PS and upgraded to a 430watt one. This MB seems to be really picky with the PowerSupplies. I read over on the OCWorkbench forums that others had PS probs.
