Lo peeps
Can I pester you for a few hints an tips :p
What is a goodly amount to have cached, I have 24hrs at the mo
but have no idea how long they will last :D
Think i saw mention somewhere that maybe intel rigs are better for rc5 , true or false.

Thanks
Jed ;)

hints, eh?

in rc5 a certain number of units will take a certain number of hours to crunch ... in OGR each stub takes a variable amount of time (but the value is based on how much crunching was done ... so harder to predict how long they will last ... especially if they happen to release any more OGR-24 stubs ... (far shorter).

To my knowledge units do not time out at all quickly so you can store up work to run for quite a while.

I think Athys are still better than intel for this project (by quite a bit if I have it right ... but I did hear thta if you are running Dnet on intel ... OGR is somewhat better use of the CPU than RC5 ...

(surprisingly ... SPARC chips seem to do Dnet pretty well too)

Oh ... and check the FAQ ... Hawkeye runs a wonderful proxy that has associated web pages that tracks units sent in ... Dnet only updates once a day but his updates every 15 to 20 minutes ... not everybody is using the proxy but a majority are ...

Unless you set up a personal proxy, your limited to 1000 RC5 blocks (If you just set up a remote buffer this doubles to 2000). My dual XP2000 rig manages around 200 a day giving around 5 (10) days worth. I believe your also limited to 1000 OGR units but these will last a lot longer (weeks). The client will happily switch to the other project if you've got OGR and RC5 work so I tend to keep a few OGR's in case I forget to update my remote clients.

If your connected once every day or so then it doesn't really matter, the client will keep itself topped up and do the oldest work first. I tend to set up my clients up as 1000 RC5 and 100 OGR.

rough figures from here:-

http://www.distributed.net/~nerf/rc5calc.html

XP1600 (1.4Ghz real) 86 blocks / day
P4 2Ghz 59 blocks / day
P3 1Ghz 41 blocks / day

P3's /P4's aren't faster than AMD at OGR but the performance gap is less. Hence if we were competing in both OGR and RC5 it makes sense to aim your Intel machines at OGR.
