Good to know. how do you get 64 GPUs?


A secret known only to a few, and if he told you he would probably have to kill you ;-)


Tell me first, then kill me.

There are a few, but the easiest way is modifying an xml file so the client believes more to be present. For example my host 7324426
7/18/2019 5:36:57 PM OpenCL: NVIDIA GPU 0: GeForce GTX 750 Ti (driver version 364.51, device version OpenCL 1.2 CUDA, 2048MB, 1967MB available, 1622 GFLOPS peak)
7/18/2019 5:36:57 PM OpenCL: Intel GPU 0: Intel(R) HD Graphics (driver version 10.18.10.4358, device version OpenCL 1.2, 1195MB, 1195MB available, 358 GFLOPS peak)
7/18/2019 5:36:57 PM OpenCL: Intel GPU 1: Intel(R) HD Graphics (driver version 10.18.10.4358, device version OpenCL 1.2, 1195MB, 1195MB available, 358 GFLOPS peak)
7/18/2019 5:36:57 PM OpenCL: Intel GPU 2: Intel(R) HD Graphics (driver version 10.18.10.4358, device version OpenCL 1.2, 1195MB, 1195MB available, 358 GFLOPS peak)
7/18/2019 5:36:57 PM OpenCL CPU: Intel(R) Celeron(R) CPU J1900 @ 1.99GHz (OpenCL driver vendor: Intel(R) Corporation, driver version 3.0.1.10891, device version OpenCL 1.2 (Build 76427))

The scheduler code has, or did have, a limit for the number it is willing to accept from the client. So any value over that would be ignored.

My original start date in 1999 is as lost as my original juno email account I used for it.
However, I do recall getting new hardware for my June 1st birthday and having already been running SETI@home back then.

A bit fitting I just upgraded my HTPC to an i5-9600K for my birthday this year after the older hardware finally gave out.
So much better doing multiple tasks in minutes instead of taking over a day to do one task at a time.

Lovely that you have done so much for this again!
Would be great to get 2 - XL. Prefer black but one of each color would be great as well.

Wearing my 15 year shirts around Philadelphia a number of people have asked me about SETI@home and seemed interested. :)

Post:
Is it possible to have 1 raspberry pi hand out work units to the other raspberry pi's in a cluster? And have 1 computer account be the go-between of all of them in the cluster and SETI? So that the cluster would look like 1 PC to SETI?

It is possible, but you will need to write the software to do it.

I've considered regooping the VRMs and PCH but they are bolted down from the underside side of the MB.
So I would have to completed remove it & that is more work that I have been wanting to do.

Post:
This isn't the first time they have had this kind of issue & I doubt it will be the last.
Something that really throws a lot of software for a loop is having a system drive that isn't C:
Most people won't have that specific issue, but as someone that tests software for a living I do like to find weird bugs that make developers walk away saying "how?!"

Posted 6 Mar 2018 by Profile HAL9000
Post:
Getting the USB miners to work for Bitcoin Utopia wasn't what one might call "plug-and-play".
A GPU is really plugging the device in and installing a driver.
The miners required manual configuration of BOINC so they would be detected and function correctly.
Which wasn't overly complicated but did have a learning curve to it.
11) Message boards : Number crunching : is there a page that shows when Top Participants was last updated? (Message 1923057)
Posted 6 Mar 2018 by Profile HAL9000
Post:
Judging by the difference between my current score and the score shown in the table, about 13 hours ago. Perhaps assume 'daily' as a plausible interval?

I seem to recall there is something odd about how the stats pages are updated.
Along the lines of when the page is requested it is updated if it hasn't been in the past N hours.
So then the time that each page can be updated gets out of sync after a while and we get people lost between the pages.

Hal, thanks for the heads up, quick question, does what you run in that batch file nuke your historical information, which would be displayed on the Statistics page in BOINC? I have mine set to save the info for something like 12000 days or some such thing, but I don't believe that this is the issue with that huge file, because the one on the machine I am on now is only around 5 or so meg, and has over a year and a half of data points, about the same as the other one (mid-2016 setup date on both).

The data for the stats graphs are stored in the statistics_[PROJECT_NAME].xml files.
I only have BOINC store the last 760 days since I backup the stat files on each startup.

Quick question, I was defraging the drive after installing and then removing .net 4.0 as it didn't work (going to try 4.7.1 when it's done) and the defrager I use has a section where it lists large files. I noticed 2 that were pretty huge, and can't imagine they are supposed to be that big unless there is some type of logging situation turned on that I am not aware of. They are both in the ProgramData\BOINC directory, and are called temp_time_stats.xml and time_stats_log.

They are both about 388 meg, which isn't a big deal in the scheme of things, but wondering what they are, if they are both needed and why they might be that big? I checked on my lotsacores box, and they are both there, but are both under 5 meg. Is there a way to shrink them down to this type of size?

As part of my startup bat for BOINC I clear out several files that tend to get left over or are of no use to me.
del time_stats_log
del http*.*
del job_log_*.txt
boinc.exe --skip_cpu_benchmarks --detach

I'm not sure what you are trying to build, but you can download the current r3584 version from
Mike's World http://mikesworld.eu/download.html or Raistmer's cloud storage https://cloud.mail.ru/public/3nxq/SgQBZXcM7/

If you need the current source you could contact Raistmer and see where it is stored.

Ok so apparently https://boinc.berkeley.edu/dl/ is now forbidden so older versions aren't available.
That's because the URL isn't needed as HTTPS.
http://boinc.berkeley.edu/dl/?C=M;O=D works fine. Or linking directly to the app, be it from HTTP or HTTPS:
http://boinc.berkeley.edu/dl/boinc_7.4.43.apk
https://boinc.berkeley.edu/dl/boinc_7.4.43.apk

7.4.43 plus the Seti applications should work fine on Android 6, it's with 7 and above that there are major problems.
Or as Eric told me once: "Yes, google keeps changing the rules in the name of (a false sense of) security. What's worse, they keep changing the development kit so a command line build of the app no longer works. My last attempt at at an android 7 build resulted in an app that doesn't work. I hope to get a chance to try again soon."

I would guess the http https change for the download directory occurred when http://boinc.berkeley.edu was setup to point to Science United and https://boinc.berkeley.edu pointed to BOINC.
It looks like Science United has been moved to https://boinc.berkeley.edu/scienceunited/

I also had to roll back to 7.4.43 on my Galaxy S4 with 4.4.4 KitKat.
With Google and the device manufactures constantly changing things or doing different implementations it can't be easy for BOINC or the projects to support.

I'd say it's software issue. 7.4.43 seems to be the last "good" (AKA working) version. Later versions seem to be nothing but trouble from what i've read on other boards.

Ok so apparently https://boinc.berkeley.edu/dl/ is now forbidden so older versions aren't available.

I've made 7.4.43 available here.

Even though my home made stand is working out fine for me, I have another board that I'd like to remote the video card on, so thought since mining has been booming again recently, I would take a look at what options I had for a reasonably priced, fairly simple stand. I guess before I started looking I should have thought about what happened in the CA gold rush, and how the people who made most of the money were the ones who supplied the miners, not the vast majority of the actual miners, who broke even, or worse.

Did a quick google, hit some links to fleabay and to Amazon, and was shocked to see what they are asking for a few cut pieces of extruded aluminum and some bolts. Mind boggling, They were all at near to Way over $100, which I guess goes along with the situation we're having in video cards right now. $25, 30, maybe, but $150-250? Umm, no. I'll keep looking to see if I can find any sanity out there, or else I'll just have to roll my own again. I'm sure v 2.0 will be much better, and won't have the special Dewalt enhancements on it this time either.. ;-)

Hmmm... I can get a 3 foot lengths of 1/2 inch alum stock at my local hardware store for about $3 & a 100 pack of pop-rivets is about $6. So I could probably put a nice little stand together for around $25.
Perhaps I should start doing that and selling them for $75 to undercut the other guys and make some cash to fund my future hardware...

MW is fine, but IIRC to do something productive there you need to have an AMD GPU, NV stuff has troubles to work with DP used by MW.

Does that changes?

GPUGrid with it's long time to crunch WU is not really a project to use as a backup. IMHO

Milkyway used Double Precision calculations.
Most GeForce GPUs are allowed DP performance of 1/32 SP
Radeon GPUs are allowed DP performance of 1/16 SP

So if both GPUs were 6000 GFLOPS in Single Precision the GeForce would be 188 GFLOPS DP and the Radeon 375 GFLOPS

If you move to the workstation GPUs they will have DP performance of up to 1/2 SP. Which is likely why they have 4 digit price tags.
