    This time, I don't think it died because of overheating. First of all, it was off. And secondly, the cooling I have on it is more than overkill (out of paranoia).

    Tried all combinations of the two processors. (switched, ran each alone in each socket)... all the same result.
    If either processor was dead, it wouldn't be seeing the same results for all combinations.

    Tried different memory modules - same
    Different power supply - same
    No video card - same

    I got it to work only once, but never again - even under the same settings. So it's going to RMA.

    I've had it with this mobo. It was designed for the Clovertowns - never meant for the 150 watt, 1600 FSB Harpertowns...
    I'll be ordering SuperMicro's version shortly before getting back from winter break:
    http://www.newegg.com/Product/Produc...-155-_-Product

    (It's big, so I've made sure it fits in my case.)

    It lacks a pcie x16, but I don't game on it anymore (my i7 rig is better for games). I'll just grab the best pcie x8 card I can find to get full resolution, Aero (Windows), and Emerald (Linux).

    *God... I'll have two extra video cards sitting around... (GTX 9800+, GTS 250)
    One of them will go into my future Sandy Bridge/Bulldozer rig, as well as the extra 1000W power supply I have sitting around.


    I'll update the charts tomorrow. lol


    I wonder what to do when I get the Tyan board back from RMA.
    I might just get a couple of low-end 1333 FSB Harpertowns to fill it. But I can't really justify it because whatever I put in it will be outclassed by my current setup (2 x X5482 + 64GB).

    It'll also won't be very useful for my code-development and tuning because it will be identical in architecture to my current setup. (and I want something different)
    Interesting. I've never built any Xeon based systems, so I can't help ya. Interestingly enough though, we've had Tyan Intel boards die on us at work. So, I dunno. They've never been cost effective enough for me to build one.

    You can always just the RMA'd board for a storage server or something.

    *shrug*

    Like I've said, I don't really like the Xeons. And the current generation ones are wayyy to expensive for me to build.
    flow man:
    du/dt + u dot del u = - del P / rho + v vector_Laplacian u
    {\partial\mathbf{u}\over\partial t}+\mathbf{u}\cdot\nabla\mathbf{u} = -{\nabla P\over\rho} + \nu\nabla^2\mathbf{u}

    Charts updated.
    The X5482 Xeons I have are the hottest chips on the line (150W). I really don't think that Tyan board I have is meant for it.
    It was released before the Harpertowns were out and the hottest chip at the time were the 95W Clovertowns.
    Similarly, 667 MHz memory was the fastest at the time the mobo was released. Running 800 MHz is pushing it beyond its design limit.

    *The specs state that it supports my configuration, but I honestly don't think it was designed to handle it - as it was probably just "recertified" for the higher line.


    Sandy Bridge due for January 9th. I get back from winter break on the 15th or so.

    So when I get back, there'll 3 motherboards waiting for me.
    SuperMicro X7DWN+
    Tyan Tempest S5397
    (some Sandy Bridge mobo)

    So I'll be building two rigs as soon as I get back.

    I have an unused CM HAF 932 sitting as furniture in my room. So that'd be a good place to put the Tyan board if I ever find a free (or very cheap) pair of LGA 771 quads.

    I have enough spare parts sitting around* to build the Sandy Bridge rig with just a CPU, mobo, and optical drive. (Though I'll probably get a good case and a cooler with it.)
    Though I'll need a new gigabit switch to put everything online at once.

    *You won't believe how crowded my room is already...
    Main Machine:
    AMD FX8350 @ stock --- 16 GB DDR3 @ 1333 MHz --- Asus M5A99FX Pro R2.0 --- 2.0 TB Seagate

    Miscellaneous Workstations for Code-Testing:
    Intel Core i7 4770K @ 4.0 GHz --- 32 GB DDR3 @ 1866 MHz --- Asus Z87-Plus --- 1.5 TB (boot) --- 4 x 1 TB + 4 x 2 TB (swap)

    I think that if I were to build a 32-core Intel system, the estimated/projected cost will be double of the 48-core system, and about 4 times more than an AMD-based 32-core system.

    If I could afford it, all of my systems would be moved to racks. Takes up less area.

    I'll probably be doing some of the 10B and maybe 25B runs on my workstation on Monday. Not sure yet.

    hey poke, ive got a nice christmas presant for you if you want it

    you can have one of my 4P tyans if you want it, to help with your code writing for the MPI.

    i just ask 2 things, if you decided to get rid of it, just send it back, and the second is to let it crunch some boinc.
    Its not overkill if it works.

    Are you serious?

    I mean... That's a 4P processor... expensive.

    To be honest, FusionIO isn't all that it's cracked up to be.

    I posit that OCZ's RevoDrive could be just as fast.

    My biggest "complaint" about them is that they're not recognized as storage devices by the BIOS, which means that you can't put the actual swap file on there.

    Which, for me, kind of/sort of defeats the purpose of having one.

    (I have it because I use it as my working directory for simulations, but that ONLY works IF I can guarantee that my simulation will not generate more than 80 GB of data during the course of the simulation, which is IMPOSSIBLE to predict realistically).

    du/dt + u dot del u = - del P / rho + v vector_Laplacian u
    {\partial\mathbf{u}\over\partial t}+\mathbf{u}\cdot\nabla\mathbf{u} = -{\nabla P\over\rho} + \nu\nabla^2\mathbf{u}

    how important is storage for this app? ie, is it constantly writing to disk as it computes?
    If I forget to say it, Thank You

    When you don't have enough memory, it depends a lot on the storage speed. See my 25B computation below. The average CPU utilization was 170% instead of close to 800%. This was more of a hard drive test than anything else.

    25B, i7 950 @ 4.3Ghz, 24GB ram @ 1790Mhz, 22GB ram, rest on a single 1TB Samsung F3 (after seeing the 10B, I wasn't wear the SSD on this one )

    Edit: Dammit, I only noticed now that it counts time elapsed since the checkpoint I had to stop it for a few minutes to use the computer. This was at 22.45PM, so the total time was around 14.7 hours. Anyway, it may not count for the top, but I did it.

    Ok. So I had a bit of "down time" in between doing CAD designs. Managed to run from 25M to 1B digits. Specs of the system are still the same. (Intel Core i7 980X 3.33 GHz@4 GHz, swap on OCZ Vertex2 90 GB SATA SSD, working directory on FusionIO io-Xtreme 80 GB PCIex4 SSD).

    Here are the validation results:

    Wow. Lots of results for me to update. I'll try to get them in on Saturday before I head off to Hong Kong.

    25B, i7 950 @ 4.3Ghz, 24GB ram @ 1790Mhz, 22GB ram, rest on a single 1TB Samsung F3 (after seeing the 10B, I wasn't wear the SSD on this one )

    Edit: Dammit, I only noticed now that it counts time elapsed since the checkpoint I had to stop it for a few minutes to use the computer. This was at 22.45PM, so the total time was around 14.7 hours. Anyway, it may not count for the top, but I did it.

    Yes, unless you're running multiple drives in parallel, it's basically gonna be a hard drive benchmark.
    Currently, the break-even point (50% CPU-limited, 50% Disk-limited) is about 100MB/s for every Nehalem Core i7 core @ ~3.0 - 3.5 GHz.
    Which means you'll need 400MB/s of disk bandwidth to get any good large runs on the original Bloomfield Core i7s. There's no single HD/SSD that can do that - and it's also beyond the limit of a single SATA II channel. So you'll need an array of drives.


    Both of my test rigs have an array of identical drives.

    My Core i7 rig: 4 x 1 TB Seagate Barracuda 7200 RPM
    My Harpertown rig: 8 x 2 TB Hitachi Deskstar 7200 RPM

    And then there's Shigeru Kondo's rig:
    16 x 2TB Seagate 7200RPM Enterprise drives
    We used this HD setup to set the world record to 5 trillion digits.

    None of these setups are in any form of RAID. The program usually seems to do a better job of managing them manually.


    In any case, I wouldn't recommend using an SSD for too long since the program will probably kill it in a short amount of time.



    A few months ago I had an e-mail chat with Massman over the possibility of adding y-cruncher to HWbot. The eventual long-term goal is to replace SuperPi and introduce a multi-threaded benchmark that isn't 100% synthetic like Wprime.

    But the main problem right now is the huge memory requirement. Since the swap modes are so slow, you basically are forced to run maxed out ram configurations to get anything competitive. (And it's pretty hard to get anything with 24+GB or ram to hit 6GHz...)
    This will mean scores will be heavily biased towards the multi-socket workstations that can run huge amounts of memory - to the point that non-overclocked(able) machines that can run more memory may beat out LN2-cooled machines that need to use a swap mode.

    The other problem is speed-consistency.
    Speed-consistency is very important for HWbot. But being able to keep up to date with new instruction sets (AVX/FMA, ...) is also important. (Just check out AMDZone for all their SuperPi bashing because it uses only x87 FPU.)
    Speed-consistency and up-to-date instruction sets are inherently conflicting... Neither Massman nor I know how to deal with this yet.

    y-cruncher itself will never be speed-consistent, but I can easily branch the program and maintain a HWbot version which I will never update or optimize (except for bugs).


    So far, we're both too busy to take this seriously yet. Hwbot will need to build an interface with GUI and score submission on top of the program. And I'll have to make some changes to help facilitate that.

    Charts updated.

    I'm leaving for vacation tomorrow and I won't be back for a few weeks.
    I won't always have internet so I'll probably be really slow with responding and updating charts.

    Well, sorta yes and no.

    Not entirely true because if you get a PCIe x4 or even x8 SSD card (it's still technically an SSD), I've topped off the FusionIO at 800 MB/s read.

    Yes, only because you stated SATA-II. If it weren't for that, then, it would have been a solid "no/not true".

    And granted, yes, most people don't have PCIe SSD cards, and the people that do have it, as far as I've been able to tell/research, can't put the swap on it because it isn't recognized by the BIOS as a stroage device (which also implies that it is somewhat "software" (driver) driven.)

    What would be interesting would be to see if the location of the working directory and the location of the swap file matter.

    I would think so, but I don't have any data/evidence to back that up/support that statement/claim.

    I take back my words on the 1st test being useless.
    Been having troubles with my system lately and the other day before I went to goto bed I was failing y cruncher instantly.
    I got her stable the next day by adjusting the drive strenths a little.

    What I'm happy about is that if I would of went to bed, and if it failed the 2nd test, I wouldn't of been happy.
    So that 1st test is cool in that respect, I didn't waste any time.
    You might still fail in a half hour or an hour, but still..., when it was failing almost instantly, I knew more work was ahead of me and that I should just goto bed and deal with it later.

    I've got her to run an 8hr run at 1.5gigs(I have 2gigs of mem).
    And that's pretty much what I try to check for now.
    If I'm going for a quick run, it's 2 hours, pretty close to where it repeats the 1st set of tests on a 3.5ghz setup with 6 cores.

    I like the ability to choose the memory limit from inside the program.

    I really like the talk of cache misses and fpu usage.
    I defently think that these are the key in checking stability:
    Fpu, sse, cache missing, and large workloads to work the ram and keep the cpu with fresh, "real" data.
    Same goes for ram in that respect, can't test ram with generic values, you gotta use somewhat random values.

    With the cache misses you force the cpu to re-read the mem, stressing the cache and the mem more.
    Might take a few ns's of stress off the cpu though but I'm sure that would be fine as long as the cpu is being fed a decent workload to continuesly go through.

    I'm defently keeping this program as one of my main stress testing verification apps.
    Along side prime and s&m.


    So far to be onest.
    I haven't found any use for linpack or linx.
    I always seem to pass those pretty easy.
    I don't think they stress the fpu or see unit's enough or something.

    So far, if I am interpreting your post correctly amidst all of the spelling errors and stuff, LINPACK should actually stress the FPU the most.

    IntelBurnTest does it a little better in the sense that it's parallel, whereas the original LINPACK is just single processor. There is a LINPACK HPL, but I've never learned how to use it or use it properly.

    And I don't know enough about coding/programming to rewrite LINPACK to create LINPACK MPI.

    If there was a version, I think that it would be very useful.

    And if you want it to use SSE, that will be compiler dependent.

    du/dt + u dot del u = - del P / rho + v vector_Laplacian u
    {\partial\mathbf{u}\over\partial t}+\mathbf{u}\cdot\nabla\mathbf{u} = -{\nabla P\over\rho} + \nu\nabla^2\mathbf{u}

    Cool. I see that it seems that I'm kinda like in the middle of the pack right now.

    I guess that it really goes to show how CPU speed is a factor for this program and I think that it scales relatively linearly to speed. So that's good.

    Have fun in Hong Kong.

    I just got back to Hong Kong from Egypt.

    So apparently, my mom was paranoid about going to Egypt directly from the states. So we went to Hong Kong first, picked up a friend, then took a Cantonese tour from Hong Kong to Egypt disguised as Hong Kong citizens... lol

    Speaking of Hong Kong: compared to when I was in China this summer, it feels much better to be in a place where I actually speak the language... (granted, everyone speaks English here anyway...)

    I'll be back in the US in a little over a week. I'll update everything then.

    If you live each day as if it was your last, someday you'll most certainly be right.

    You speak Cantonese? Cool!!!

    I don't. Well...except for ordering food. But that's funny! LOL. I probably would have agreed with your mother if you were saying going to Iran or something like that. But Egypt shouldn't be THAT bad.

    Thanks! Last time I was here was 13 years ago. So it's almost completely new to me.

    Ordering food. If you ask me, that's pretty important. It's hard to get around without food.

    My Cantonese is native, but not fluent. (It's my first language, but having been in the states all my life, English is obviously my strongest language.)

    EDIT:
    I wanna learn enough Japanese to go to Japan to meet Shigeru Kondo. From what I've seen/heard, few people in Japan outside of the tourist areas speak English.
    Right now, all the Japanese I know is from Anime - which I know is not enough (nor appropriate) to use on the streets.


    My mom is kinda afraid of the whole middle east... But I also think it's a little over the top.
