This is a screenshot of the host average from my BOINC client taken a few minutes ago. I'll have to get the other information from this website and post it. See if this helps any. You can see the jump in performance on my end!

@utp216, thanks for the picture. Your points sure are increasing!
----------------------------------------I'd love to see the CPU benchmarks run by your BOINC manager, and an excerpt from your Results status/Return time on the WCG web page. Thanks! ![]() |

Since I have not really seen much on the performance of the any AMD FX/Bulldozer chips here I thought I would toss my two cents worth in the ring.
----------------------------------------Because of a need to be able to test and support code on a variety of AMD processors I picked up an AMD FX-8120 the other day and put together a modest system from parts I had laying around. My "baseline" system uses the 8120 at its native clock speed of 3.1 ghz and 8 gig (4 sticks) of ddr3 / 1600 memory. Currently the memory is running at only 1333 mhz which is what the motherboard defaulted to. The hard drive is a conventional Hitachi HDS72101 7200 RPM 1 TB unit. At this point I am running "box stock" copy of Ubuntu 10.04. Please note that with the original 2.6.32.12 kernel supplied with Ubuntu 10.04 had a "incompatibility" with the version 0707 BIOS on my Asus M5A88-V EVO motherboard which permitted it to see only half the installed 8 gig of memory. The problem centered around the handling MTRR's - running the standard post-install update brought in a new kernel (version 2.6.32.35) which resolved this issue. Because of their ultra-consistent task size / run time I am doing my initial shakeout of the system running Poem@Home. Once I have the hardware setup the way I want (moderate overclock, memory speed, blah, blah) I will slide this system over to WCG. In this standard configuration it is taking the 8120 about 94 minutes to complete a Poem work unit. Compare this to a Phenom II 925 overclocked to about 3.2 ghz. The Phenom II executes the same work unit in about 82 minutes. To be fair, the Phenom II is running a highly optimized 3.x.x kernel should cut that gap from 12 minutes to about 7 minutes. And since the FX-8120 is a "black" processor I expect that I will be able to cut the gap further by raising the clock multiplier up a bit. However, cycle for cycle, it is clear that the new AMD FX processors are doing less work than the older Phenom II CPU's. (This observation is reflected in the many benchmark reports available on the net) (It should also noted that these formal benchmarks attempt to lay a portion of the blame for the FX's lackluster performance on how the Window's 7 dispatcher manages multi-core CPU's. However, since I am running Linux that variable is no longer part of the equation) With all 8 cores cranked up to 100% the 8120 is running about 51C using an Antec water cooling system with an ambient room temp of around 78F. This is slightly less than what I see with the Phenom II processors. To do another slightly skewed comparison, in this standard configuration the AMD FX-8120 is at least 10-15 percent faster than the 2.6 ghz Xenon 2.6 (Nehalem) processor in my year-old Mac Pro (4 real cores acting as 8 thanks to HT) So in terms of raw throughput, you might do better with a Phenom 1100T. However, with the extra two cores available with the FX series I suspect that FX will do slightly better on total throughput.

This is what I could come up with tonight. The first CPU is my original rig that I haven't updated since 2007/2008.
----------------------------------------AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ Tue 22 Nov 2011 02:22:23 AM EST Number of CPUs: 2 Tue 22 Nov 2011 02:22:23 AM EST 1828 floating point MIPS (Whetstone) per CPU Tue 22 Nov 2011 02:22:23 AM EST 8390 integer MIPS (Dhrystone) per CPU AMD FX(tm)-4100 Quad-Core Processor Tue 22 Nov 2011 02:14:17 AM EST Number of CPUs: 4 Tue 22 Nov 2011 02:14:17 AM EST 2408 floating point MIPS (Whetstone) per CPU Tue 22 Nov 2011 02:14:17 AM EST 11145 integer MIPS (Dhrystone) per CPU I was looking at one of the Phenom CPU's before I got this. I couldn't pass this deal up though. I got the CPU and a ASRock Deluxe5 motherboard for $200 cash from my nephew who went Intel. And he tossed in the 8GB of RAM for buying the CPU and board. I am also running Ubuntu 10.04 LTS. If that matters. [Edit 1 times, last edit by Former Member at Nov 22, 2011 7:31:19 AM] |

This is the best information I've seen anywhere about Bulldozer performance in crunching, and the fact that you're testing on Linux makes it especially helpful to me. Do you know whether Poem@Home WUs are heavy on integer or FP computations? ![]() |

Let me know if your nephew is selling any more hardware .Thank you for the benchmarks, and for mentioning that you ran them under Linux. There seems to be some difference in how BOINC does benchmarks under Linux versus Windows. ![]() |

I can't afford to have a dedicated PC for BOINC/WCG, and I have only one desktop for everything, whose idle CPU time is used by BOINC. However, since I depend on it for my work, I try to keep it fairly up-to-date as much as I can. It has an AMD Phenom II X6 1090T processor with 8 GB Kingston DDR3-1333 RAM (4 x 2 GB), running 64-bit Windows 7 Home Premium. (It also has an HD6850 video card that I bought chiefly to have APP/OpenCL support, as I'm not a gamer, so otherwise it's overkill for me. And I'm frustrated by WCG's current lack of significant GPU processing support.
)I keep all six cores busy with WCG crunching and allow BOINC to use up to 95% CPU time, conditioned however to less than 20% non-BOINC CPU usage. (You bet I have a good aftermarket CPU cooler, too.) The BOINC client yields priority efficiently as needed, and I rarely have any noticeable slow-down in my other activities. If eventually I need to do something heavier, like running VMware or converting a video (neither of which is a routine task), I suspend the client temporarily and resume processing after the job is done. Results have been good so far. I am just now returning to BOINC after a 3-year gap, because my old PC (which I had until late 2010), a vintage Athlon 64 3800+ from 2005, had processor overheating problems and BOINC worsened that problem, so I had to give up. I don't remember the scores I used to have back then, but I do remember jobs taking whole days or more than one day to complete. Of course there is no comparison between a 2.4-GHz single-core processor from six years ago and a 3.2-GHz hexa-core processor that is also two (and arguably a half) architecture generations newer. Most jobs here are completed in significantly less time than estimated - jobs scheduled for 10 hours finish in 6-7 hours, 6-hour jobs finish in 4:30 hours, and so on. I've been achieving a 1,100+ point a day average (though this is likely to fall in January, as I will have to go back to work at the office and for safety reasons - lightning strikes and such - I won't be able to leave my PC on 24/7 as I do now). Considering the disappointing results that Zambezis have been showing in nearly all tests, I'd say that Thubans like mine (which can still be found for sale) are probably still the sweet spot of optimal price/performance ratio when it comes to AMD processors - probably even more so now, as prices have fallen. My processor is not overclocked because so far I've felt no need for that, but it's a Black Edition model and that could easily be done, adding even more value to it. Also, at least at stock speeds, Thubans have superb thermal efficiency and barely heat at all if they have a good cooling system (AMD's stock cooler is definitely not indicated for a PC that is going to do heavy crunching). What do you think of a six-core processor running at 100% usage most of the time that still hovers in the 32-36ºC range (90-97ºF) as the Southern Hemisphere summer approaches and days are already often hot here, with no a/c in the room? True that an 8-core FX-8120 or FX-8150 would have two additional cores to crunch data, but they cost much more and results probably wouldn't be better enough to justify that expense. There are maniacs who use Opterons on desktops, but that's probably the worst price/performance ratio possible. And if one REALLY wants performance, at this moment the crown remains with Intel and its Sandy Bridge processors (the Extreme Core i7s are so expensive that they hardly count). That could change with Piledrivers (second-generation Bulldozers) in 2012, but I'm not holding my breath. As for RAM, jeez, 16 GB are an INSANE amount of memory! I gave the BOINC client freedom to use almost all it pleased, but I still only go over the 4-GB barrier when I use VMware - otherwise, memory usage is usually between 3 and 3.5 GB here, multitasking a lot and with BOINC running. In fact, VMware was the only reason why I put 8 GB here, otherwise 4 GB would have been more than enough - as they certainly are for 99.99% of all users. Even with VMware, I'm yet to see memory usage go over 7 GB. More than 8 GB are justified only if you have, say, a professional high-end graphics or video workstation or a powerful multiserver machine running many server VMs. Otherwise, all that RAM will most certainly be idle and wasted 99.9999% of the time. So, think well. I'd advise the original poster to stick to the current configuration and be happy. . . |
