Hello All,
Does anyone know if PC's/Laptops running the new intel dual thread, 4 core intel core i7-860 processor plus Wondows 7 will run 8 concurrent FaaH jobs on the world Community Grid (i.e. 1 job per thread). Thanks. Michael2901 |

Thanks. Michael2901 No doubt it will... but there has to be enough RAM in the box, thinking that 4Gb will easily do this when the actual observed maximum is like 160Mb per job for FAAH.

Thanks. Michael2901 Mine is doing 8. If I do 4 it only uses 50% of the CPU. I don't really understand this technology. forgot to say I am running windows xp. I don't know how to tell which i7 (-860 or whatever) that I have  [Edit 1 times, last edit by I need a bath at Apr 21, 2010 1:15:14 PM] |

hmmm, task manager reads out 12.5 percent max per CPU. If BOINC is set to use 4 threads with HT still on, then guess it will show 50% max... but it's still 100% per core. The run times per task should be different [shorter] compared to 8 concurrently. Hypernova tested and he came to an overall work unit completion with HT for the HCC science of something like 8.5-12% i.e. on wallclock there was 2x more CPU time recorded, but just 8.5% more work units... i.e. each running longer in the range of 90%.

Hmmm back atcha. It therefore sounds like only very slightly more work is done with the 8 vs the 4. However the amount of cpu time is overestimated (something badgers might like) if I understand correctly, which maybe I don't!

No different than a slow P4 running a Wu that takes 23 hours to crunch while a new C2D may take only 6 hours for the same WU |

----------------------------------------Yes, HT quads are great CPU time aggregators. And let me take the 8.5% back as that was due upping the RAM clock speeds... the gain was as per this quoted post about 14%. That's with very optimized HCC with barely any Page Faulting left. The results for HFCC and FAAH may well be different: Here are the final values for Returned Results over 13 days including Pending Validations. For Points and Runtime refer to my previous post above. ERIS (HT OFF) 1093 PLUTO (HT ON) 1249 (+14,2%) Adding PV has improved a little the picture in favor of HT. The test is now finished and HT is ON again. Conclusion: use always HT ON for WCG crunching. peace P.S. I may do a test in the future with two identical i7 980X rigs and see if we get similar results. edit: address [post in between]

thanks. This computer is mainly for other work than crunching so ultimately I will select core # based on performance in other tasks but it is interesting to know how it impacts wcg.

I don't know how to tell which i7 (-860 or whatever) that I have Without going into any OS specific details the message log of your BOINC client should normally give you this info.Look for a line like this one (mine) Processor: 4 GenuineIntel Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz [x86 Family 6 Model 15 Stepping 11] at the top of your message log. The processor reference is normally the right one. But the clock speed is always the official one, even if you overclock. |

Cool! I see now that I have an 860 @ 2.80GHz
