21) Message boards : Number crunching : Seti fundraising via Bitcoin Utopia (Message 1602676)
Posted 3 days ago by Profile HAL9000
My machines started running out of work on Saturday and, since there are no other BOINC projects that I currently support, I shut them down as the WUs ran out. Checking my electric usage from Saturday through Monday, I can see that I've used 64.24 Kwh less than the same period in the previous week. At Tier 4 Off-Peak Winter rates, that translates into a $17.53 cent reduction in my electric cost for those 3 days.

Now, I suppose I could fire up those machines again to run Bitcoin Utopia, but I seriously doubt that 64.24 Kwh of usage would generate $17.53 in benefits for S@h. In fact, I'm going to hazard a guess that it wouldn't even generate 80% of that amount. (I could certainly be wrong about that, but that's why I was asking my original question.) Frankly, I'd rather save my electricity (and the environment) and turn some of my savings directly over to S@h. So, using my 80% guesstimate, I'll put my money where my mouth is:

Your gift details… You gave to: SETI@home We received your gift of $14.00 via xxxxxxxxx on 11/19/2014. Your confirmation number is 139610.

My home machine are on because they are doing other tasks rather than purpose built to run SETI@home. If I was paying as much per KW/h as you. I would probably let mine run idle rather than run other projects. Running SETI@home adds ~8-9 KW/h a day to my usage. I have found running Bitcoin Utopia adds ~6-7 KW/h a day.

Can I run the installer on a fresh installation of BOINC before receiving any work?

So long at BOINC has been attached to the project everything should be OK.

I would expect it is VirtualBox being disagreeable on your system. On one of my server I use VirtualBox and has to roll back to an older version, 4.3.14, because the most recent version at that time was a bit broken.

I've been waiting for someone to inadvertently answer my question...because it seems so obvious I'm afraid the answer is something I've simply overlooked. I'm almost afraid to ask it. So...I thought the SETI@Home MB database was much larger than the AstroPulse database. If so, why does the MB database seem fine where the AP database is not so fine?

Fair question. Just to get it out of the way - in BOINC terms (the bits we interact with - either through this forum or via our client processing), both MB and AP share the same MySQL database.

It's only at the science (Informix) database level that they're kept separate. I'd agree that in theory, the AP database should be smaller: the search has been running for a shorter time, and each 'tape' generates fewer WUs, with similar signal limits to the SETI search.

Reading between the lines of Matt's Technical News (Feb 16 2012), I'd suggest that certain limits have to be set by administrators when a database is first set up (the number of extents in a table, for example). Perhaps that has to be done to fit the amount of available disk space, or something. Perhaps the AP database was set up and configured - when it was young and small - to fit on a server with limited disk space. Since AP has been gaining a lot of attention recently, and the table sizes have been growing unexpectedly quickly, maybe they hit one of those in-house configuration limits sooner than expected?

I wonder if in newer versions of Informix some of these issues are easier to deal with. I would imagine the db software isn't changed often, but perhaps it could reduce some of their headaches. Looks like the most recent version was released this July.

SP / DP was to be my next question but that's been answered, so it looks like if you had the cash a Dual 18 core Xeon box with 2x Titan Z's would be the best bet?

Damn when I win the lottery I am defiantly building the worlds best home Seti box, something you can still run off the mains and use day to day I think, would be awesome getting to play with that kit and giving something back with all the power :)

You don't really need that much CPU oomph. An i5 or i7 with a pair of those GPUs would likely be in the top 15-20 computers for the project. The CPUs, in comparison to the GPUs, would only account for a small fraction of the work the machine completes.
26) Message boards : Number crunching : iGPU tuning (Message 1602547)
Posted 3 days ago by Profile HAL9000
When I installed my amd cards (2), they told me to first uninstall the igpu before installing. On my bios I can reinstall the igpu or so it looks like. If I do that and it works, how will that affect my gpu crunching and my cpu overclocking. I would like for the igpu to handle all of the daily screen work and have the amd's just working on wu's, but I don't want to see any downgrade in the gpu's or the cpu's. Will that work do you think? Thanks.

I still have no idea why you would be told to disable the iGPU & I have not seen any documentation about doing that before.
Using the iGPU for your general display shouldn't be an issue for CPU & the add-in GPU's processing. I have the iGPU enabled on my systems & only see slowdown issues while using the iGPU to process work.

Milkyway gained over $3,000 in fundraising from Bitcoin Utopia. This has potential to be significant for the funding Seti needs.

That doesn't actually answer my question. If that $3,000 required more than $3,000 in electricity to generate it, then it's a net loss to the project (versus direct contributions equivalent to the electric costs) and environmentally costly at the same time.

So, to figure out if it's advantageous or not, it seems to me that there needs to be a way to come up with some sort of cost / benefit ratio for this kind of approach. Is there?

Different coin types have different profit/power expense ratios. BitCoins are not profitable to mine on CPU or GPU hardware any longer, but there other coin types that are. Bitcoin Utopia mixes various coin types in each Campaign

Since my hardware will be running other projects while waiting for SETI@home work anyway. Why not help out the project while it is offline or out of work.

Well, the most anoying change is that they changed the font being used and now the columns don't show up as nicely as I had them adjusted before... :(

You could overwrite the boincmgr.exe with the previous one. The manager application is just a front end GUI to the client app boinc.exe.

So just a thought, what kit out there would perform the best for Seti?, Im not talking big clusters ect just specific pieces of hardware.

I would assume it would be some form of GPU but what about the Intel Xeon Phi cards for example?

I'm not looking to purchase just curious as to what the ideal Seti rig would be :)

I'm not sure that anyone has developed any SETI@home apps for the Xeon Phi hardware yet. However at the moment the best performance per watt would be doing work on GPUs. The type of work depends on which vendor hardware is the most efficient.
For SETI@home (MB work): NV GPUs using CUDA
For Astropulse (AP work): ATI GPUs using OpenCL
That isn't saying MB work on ATI GPUs or AP work on NV GPUs is bad.

In the NV range the 750ti seems to be the best PPW GPU. I have not seen enough reports on the new NV 900 series GPUs to know how well they preform at the moment.

The task limits were implemented quite some time ago. It was necessary to prevent the db server from crashing on a regular basis once there were too many results out in the field.


Do we know if these were h/w or s/w caused crashes? If, as I hypothesize up thread, they were because of inherent flaws in Informix, I reiterate my request: can't we get a cut-rate license from an Enterprise-grade DB for SETI? Does anyone here have any useful knowledge about this? Or can we (maybe) start a drive to buy a license? Might it be more useful than new h/w?

IIRC it was the table that holds the results out in the field taking to long to be parsed every time there was a request in the db for it. Which happens often.
I'm not sure any amount of software can work around that. It would most likely take a DB redesign or more robust hardware to handle such a workload. With a single table growing to 11,000,000+ rows it is more logical to reduce the number of entries in it. Rather than spend time redoing the works or throwing hardware at it.
That's not to say if they put a 4 socket server with 2TB of RAM & enterprise SSD storage on their wishlist that we wouldn't try to make it happen.
They also have access to DB services from the Berkeley IST, but I would imagine they would have looked in to what is offered vs what they require already.

Since I returned to Seti 2 weeks ago I crunched 70 000 credits, but at least 25% of time I was without work. I tried to make bigger WU stock as I knew this is going to happen as you warned us, but Boinc informed me: I got max.WU allowed for this computer.

Do not get me wrong but that is just stupid - it is not same to have same MAX number of WU for some old computer or for new I5. I crunch max number of WU in 2 days without any problem. And now this computer is empty for last 24h... And who knows how much longer it will be. Yes, I know - I can run Einstein or something like that in meantime, but I returned to SETI...

The task limits were implemented quite some time ago. It was necessary to prevent the db server from crashing on a regular basis once there were to many results out in the field.

As I write there are currently just a little over 1.9 million results out in the field. It will be interesting to see how low it will get, also interesting to see how long it will take for everyone's cache to be refilled when a steady flow of data comes back online

Out of the ~500 tasks across my machines most it consists of the remaining AP work they have to finish. My two fastest groups of machines are only managing to snag a new task for MB or AP every now & then. Limping along on their backup projects.
34) Message boards : Number crunching : v7.21 Differences between armv6-vfp and armv7-vfpv3d16 ??? (Message 1601963)
Posted 5 days ago by Profile HAL9000
Your device will randomly be assigned one of the following
7.21 (armv6-neon)
7.21 (armv6-vfp)
7.21 (armv7-neon)
7.21 (armv7-vfpv3d16)
7.21 (armv7-vfpv4)

Once each app version has at least 11 for "Number of tasks completed". Then the server will primarily, in theory, only send you the best one for your device.
By looking at the Application details for your device you can see the number and type of apps you have already run so far.

Well I suspended apx 40 GPU tasks one at a time, what a pain and it is now crunching. It should be done in a couple of hours or so. I hope I remember to restart the paused ones so work continues.
I really don't like micro managing data.


Here is a little .bat script I use to suspend my AP tasks. I have 4 .bat files setup to suspend or resume AP & MB separately. You just have to change bmc2 & tsk_stng to suit your needs.
@ECHO OFF pushd %~dp0 set bcmd1=--task set bcmd2=suspend set max_task_rep=5 set tsk_stng=ap_*.* set project_addy=http://setiathome.berkeley.edu/ set project_path=%~dp0\projects\setiathome.berkeley.edu\ set lcnt=0 :loopy if NOT exist %project_path%\%tsk_stng% @ECHO No tasks found & goto end @ECHO Starting AP_%lcnt% tasks set to %bcmd2% %time% for /f %%a IN ('dir "%project_path%\%tsk_stng%" /b /OS') do boinccmd.exe %bcmd1% %project_addy% %%a_%lcnt% %bcmd2% @ECHO Finished AP_%lcnt% tasks set to %bcmd2% %time% @ECHO. if %lcnt%==%max_task_rep% goto end set /a lcnt=%lcnt%+1 & goto loopy :end if "%1"=="auto" goto ext timeout 5 :ext exit

I believe the idea is so that apps written in OCL can be "easily" compiled for CPU, iGPU, NV GPU, or ATI GPU.

They have added more tapes but these aren't very big tapes so will have to see how long they last.

I think this one will have the signal from ET.

Bitcoin Utopia always has CPU & GPU work available and can benefit either Boincstats or Milkyway in the process.

The campaign for the replacement BOINCstats hardware has been completed. I have mostly been focusing on the "The Economic Viability of Mars Colonization" campaign & recently started on the 2nd Milkyway one.
I think it would be neat if there was a reoccurring one for SETI@home. Much like the Milkyway one. Seems that more than $1,000 a month can be generated at the moment.
