Seems to me like you've done a pretty good job James. I know it isn't apples with apples with memory speed variations etc having an impact but, using my x5660s running at 4.2GHz as a baseline, the approximate back of a *** packet calculation gives: Dual X5660s at 4.2GHz (24 x 4.2 = 100.8GHz) = 22.50 mins tpf Dual W5680s at 3.46GHz (16 x 3.46 = 55.36GHz) = 40.97 mins tpf Dual X5650s at 2.93GHz (24 x 2.93 = 70.22GHz) = 32.30 mins tpf The above assumes you're running at stock but with turboboost on. The biggest potential improvement would be in switching over the 5650s.
Oops, I just realised I got the model numbers wrong, and have actually switched over the rig with a pair of X5680s (24 x 3.33GHz). Therefore, given the numbers in your last post, it still seems like its underperforming significantly. Time to bash it with the naughty stick on Monday!
5680s! Where did they come from? I just love the way you can dip your hand into a bag of tricks and pull out a pair of xeons Naughty stick time indeed. Give us a shout if you need any help.
From my desk drawer of course, AKA the bit/CPC processor museum Thanks for your help so far phoenicis, the newer Linux distro has definitely helped, plus it comes with a pre-compiled version of HFM, which makes the whole system much easier to manage
Some help required please good folks... I've installed Ubuntu 11. and then followed the instructions here and it runs, but only on a single core. Any ideas how I get it to run on 12 cores instead of only the one? Many thanks Mike
Ubutu 10.10 with a various tweaks, as described in this guide. It sounds like you forget to set any flags when running the client. For bigadv you should run './fah6 -bigadv smp 12' or for beta bigadv './fah6 -bigbeta smp 12' You'll also need a passkey to get any bonus points.
Thanks James. I've changed the text file so that it matches your switches, and saved it, then re-run it. still only 1 core, buit now it's a different one (7 instead of 1) I guess I'll have to wait till the workunit has completed...
Oh yes, sorry, forgot to warn you about that. SMP and single-threaded WUs are different, so the switchover will occur when the next WU is downloaded.
That should be './fah6 -bigadv -smp 12'. Notice the hyphen before 'smp'. You don't really need the '12', if you don't have a number the client will take all the cores it can find. Afterthought - I've never tried using 'smp' without the hyphen ~ so perhaps it isn't obligatory either.
I've just spotted a mistake in my passkey. Have re-entered and it's looking a bit more promising now as it's deleting the existing work unit Batch file that's created needs the - switch before each parameter, otherwise it gives an error, so I'm trying it now with... ./fah6 -bigbeta -smp 12 Looking good so far.... Will report back later...
