so u dont like your chances against it at 40/120? i'm pretty sure u can hold it to an indefinite draw if u played for such a goal.
the draw rate for a cc match btwn u and the cluster should be very high, at least 85% i'd imagine (probably closer to 90%+). if so, it means even in the extreme case where one side goes undefeated, his elo delta will be held to under +50elo.

i did not say that.at longer time controls i have better chance of a win.

true. altho it may take you over a yr to notch your 1st win (since corr chess plays so slowly).
Hi,
Still trying things with Pauls comp, I had to increase the vcore a little more and although Paul feels happy enough with one of the cores hitting 70C when the machine is fully loaded I do not think I want to push it any further on air cooling, don`t get me wrong I feel there is still more under the hood but in a case 1 CPU will always run hotter especially with air cooling.
I may yet back it off to 4.2Ghz depending on how more tests go and after Paul tests the machine at my place on sunday.
I think I will save some profiles in the BIOS just in case :D

The pic below is only with 8 cores being benched as this is the max the old fritzmark can handle

Rybka 4 KNS from the start position below

u're so close. now try to break 1 mN/s! 
anyone know the speed of lukas' cluster?

i am sure with Large Pages you could hit the magic number everyone appears to want to see.
Hi,
I was egged on to break a certain KNS with Rybka which I did below although the KNS was jumping around a bit, I had to increase the speed a little. I must admit Pauls comp was not stable at this point on all benchmarks and I had a few BSOD`s so the speed has been dropped back to 4.3Ghz ... To get it stable and go above 4.4Ghz you are going to need 1.45 Volts through the CPU which on air is prob a bit iffy especially as the machine will be in a room which already has a skulltrail and this new comp heats my kitchen quite well already lol :D ... On Water it is easy on my 6 core I am 4.5Ghz and now I have fitted the watercooling setup I am a full 15C lower temps wise fully loaded


On Pauls comp with windows 7 for some reason others may explain when I enable Large Pages the KNS actually drops

just over 1mil nps. very sweet indeed!
a request: to determine r4's scaling efficiency, can u disable all but 1 of the cores, and then tell us the kN/s for the single-core (at that clock speed of 4.37ghz)?

> to determine r4's scaling efficiency
Well, first Bigben should tell us if the million nps was obtained at each try (multi-core numbers are known to be non reproducible
)
i thought the variance had mostly to do w/ time to depth and not so much the node speed? so while it may have taken 9s to finish 19ply in his screenshot, it may take 8, or 11, or 12s, in other attempts, but the kN/s remains fairly constant. i remember vas saying this is due to the non-deterministic nature of the shape of the search tree.
am i mistaken?
am i mistaken?
> but the kN/s remains fairly constant
Well, try it (if you have a Dual, a Quad): 5%, 10% variations are not unusual...
i dont have rybka. a 10% variation in node speed is small compared to the variance seen for the ply depth metric.
>Well, first Bigben should tell us if the million nps was obtained at each try (multi-core numbers are known to be non reproducible )
Hi Ernst,
It is reproducible but you are correct in that at times the KNS jumps wildly about with Rybka 4 ..... At times when I have increased speed including memory timeings and increased the scores on all other benchmarks along comes Rybka 4 at the start position and the KNS drops


.... So the figures should only be used as a guide but fast is fast in the 12 cores case.Other scores posted is seeing Zappa Mexixo 2 running at 10500000 KNS
If I get some spare time I should show the CPU scores in the Everest Benchmark where of course the 2x 5680 trounce my 980x .... I only have today (saturday) as Paul is picking the comp up tomorrow but I have the gym today and some of my friends are fighting tonight at http://www.circustavernnightclub.com/events/sporting-events/517/iba-boxing-september-4th-2010- .... I do not have much testing time left

Regards
using your 710 knps figure as a ref, i'm guessing the single-core node speed should be ~170 knps. that would mean the 12-core beast has a scaling efficiency of ~50%.
so how close was i?
so how close was i?
Wow, that is amazing! Congrats!
Hi Chaps,
I posted a reply with quite a few benchmarks including what JP wanted with Arena2+cyclone extreme benchmark but I had included a bench of one of the clones for comparison between 2 machines and the whole post was deleted by the moderator rather than taking out a couple of the benchmark pictures (I simply forgot I was on the main forum)
It is annoying as I put a lot of work and time into the post before I left for the boxing venue ... If you did not get to see the post before it was moderated\deleted my apologies
Regards
Tony

as soon as i saw Sravinsky engine mentioned i knew this would happen.nice to know that it scales well on 12 core though unlike a certain other engine.
paul, since i presume u have the 12-core now, can u run r4 on only 1 core and post the kN/s screenshot for it (starting position)? i want to see what the scaling efficiency is for your 12-core (using a single-core as a reference).
afraid you will have to wait.we loaded windows 7 64 prof on an OEM version i bought and already used on another build.microsoft are objecting to this,when i entered serial no.they said security error and crashed the system 20 min later.may have to pay again.
damn mickeysoft, sorry to hear that. post it when u get a chance. thx!
i have asked felix if there is anyway he can transfer them to another place or did he just delete completly.
Maybe the moderators can remove the offending info and repost it??
Hi,
Paul has just left with his computer so my work is done, it is a shame the post was totally deleted.
The machine is running at 23x187 = 4.3Ghz .... I had been testing 22x196 but it seems around 190 is the max for the motherboard and although it ran and completed some benchmarks it was not totally stable.
For anyone wanting to try the same kind of setup with watercooling or phase etc my only hint of caution is that you cannot exceed the x25 multiplier (unless you use Turbo mode and that brings other probs which may be corrected with a new BIOS hmmnn or maybe something alters if you choose the extreme cooling enabled option?) and if the max the motherboard can run at is 190 that equals 4.75Ghz, you are going to need the board to get to 200 to make 5Ghz ..... Wish now I at least enabled the extreme cooling option to see what happened but time was of the essence

Tony

Told you we need to move enmasse to another forum.
Thanks Tony for testing..and yes i have see your post just in time 
I read also that Paul has taken his new toy to home..so maybe later when Paul has time he can retry the test..and if he want he can
post the results on Xtremesystems!
Thanks for your time..and see you later!
Kind regards,
JP.

Has been moved to the restricted sub-Forum The Edge (see the thread "Clones"

Tony, Paul,
Did you get the SR-2 motherboard in the UK or from abroad?.
At the moment there does not seem to be a local supplier here in the Netherlands :-(

Thanks, will have a look to find if they deliver outside the UK.
well worth getting,my comp now runs 2.5x times faster than my Skulltrail.thats kN/s.
Hi NATIONAL12,
I assume this set up is better then I7980x?
I assume this set up is better then I7980x?
well yes,2x Xeon 5680,s is more or less like 2 I7 980,s.the main prob is getting rid of heat.see testing on The Edge(clones thread) by BigBen.
Paul! Good luck with your new machine. I hope it brings you a great deal of satisfaction and fun.
i a still confused which processor is currently the best (for chess) in terms of price/quality
http://www.cpubenchmark.net/high_end_cpus.html
have also posted on the edge thread

When is this I7 x 995 coming out and whats the price.
i have no idea, just found this link ;)
>I assume this set up is better then I7980x
Hi,
It certainly is better but overclocking is better with a single chip as the motherboards are in many ways more advanced especially with memory support.
I think and I have not got there yet but a 980X at 5Ghz will push Paul fairly close but a lot depends on scaleing

quick question i know u are oc'd, im running stock speed's no OC'Ing, and my voltage is over 1.3 , is this normal for an AMD phenom ll x4 ?.. here is pic.. also my computer says i have am2 socket, this CPU shows i have am3+ , i want to upgrade to the BE1090T and OC to 3.9 or 4.0++
Hi chess_pr0,
Since I have never used any of AMD Phenom processors I really cant comment but there must be members of the forum who have some knowledge

Tony

i know you said that Fritz benchmark only works up to max of 8 cpu.i reloaded DEEP RYBKA 4(chessbase) and it gives me readings on 12 cpu.
54.14

have a great holiday.
my Skully gave 35.03

Hi,
That must be built into the chessbase deep rybka 4 software ... I was running the one from http://www.jens.tauchclub-krems.at/diverses/Schach/fritz9_benchmarks.html .... Which is as I thought an out of date one.
Thanks for that Paul, I think it puts you top of that benchmark list in the link above lol

my flat is like a sauna now running all these computers,maybe air-con is the answer or buy somewhere else to live.
Or put a bunch of computers in your basement and control them remotely - like I do.
in my flat there is no basement.i do have a spare room but it faces east.anyway it was only meant as a bit of fun.
i do expect another hike in electric bill though.

You know you are a computer chess addict when you look forward to the winter to really crank up all your computers for AN
not just me.BigBen(Tony) also.dont think Majid has this luxury.
