1) Message boards : Number crunching : Raspberry Pi 3 (Message 79693)
Posted 4 Mar 2016 by FoldingSolutions
I've just procured one of these little raspberry pi 3's and take delivery of it today. Main reason for purchasing was just to use as a little toy to experiment with various uses. But I think it will be quite cool to have such a little box crunching my favourite project too!

I haven't seen anywhere on this thread however any mention of if Rosetta will even run. Looking at the applications pages it seems that the ARM version of Rosetta runs only on Android, and the most common and efficient OS's for RPi are Linux based, such as Raspbian (Debian Linux) (I know android is Linux based too but pretty sure they are different in some major way).

Basically, will the Linux version of BOINC download the ARM application? Or will I have to install one of the crumby versions of Android developed for RPi to run Rosetta?

Ok after much messing about, I now have a Xeon (I went for the D3 option) but not the same Xeon as Chilean, Oh well, it has to be better than the Opteron before!

Great instructions Chilean, managed to connect no problem!

I went for the "basic" 4 core option as it was the cheapest for 4 cores, however I have ended up with this sketchy Opteron machine xD

Which one did you go for as you seem to have a Xeon with 16GB memory?

WRT the Google one - I also seem to be chewing through the credit at about $5 a day, so will just about last out the 2 month period.

I tried the Azure console, but found it very confusing to use.

Looks like you have to use some sort of third party SSH protocol to access the server.

Any tips @Chilean?

Microsoft Azure also gives out 200 free credits. Which amounts to this host for 1 month.

Nice link :) thanks will check it out

I agree, I also use my machine to heat my front room!

It is pretty pricey and probably doesn't make much sense from a cost perspective. Unless you're in a situation like time and want a short term boost :)

I found this interesting thread on the Einstein@home forum, but I don’t really dig that project as much as Rosetta, so I persisted on finding a way to get Rosetta to run on it instead.
In a nutshell, Google Cloud compute offers 60days of free compute time (or $300 of usage, whichever comes sooner). I will copy and paste some of the Einstein thread to avoid repeating unnecessarily. Credit to the user Michgelsen:

Here you can create one or more virtual machines, up to a combined total of eight (logical, with hyper threading? don't know.) Xeon cores, with a selection of operating systems to choose from, such as Debian, Ubuntu or Windows Server.

I chose to start an eight core machine with 8GB memory with Ubuntu 15.10 (be sure to select the boxes which allow http and https connection to the internet).Once it is created, which doesn't take long, you'll see it under 'Compute Engine' > 'VM instances', and you can see 'SSH' and a few dots to the right, under 'Connect'. Click the dots, then choose 'open in browser window', and now you can simply interact with the machine via a CLI through your browser. Very neat.
A few remarks/limitations:
- No GPU processing.
- No GUI for your VM, as far as I know.
- I tried, but failed to run a project (ATLAS or vLHC) needing VirtualBox in the virtual machine. Maybe nesting VMs is not possible, or I did something wrong. Either way, I stuck to Einstein, as a 'normal' CPU project.
- Mining cryptocurrency via this method is forbidden by Google.
- You will not be billed once the trial period is over, i.e. the trial will not automatically change into a paid subscription.
- Whether you can use the full 60 days depends on how powerful the machine is you create. You get $300 to 'spend' on machines in 60 days, and more powerful machines cost more.
- I must say, hats of to Google for creating this very easy-to-use browser-based interface and for letting people test it for free!

Now, installing BOINC is as simple as copying and pasting the following command into the UI that pops up once you start your instance:

sudo aptitude install boinc-client boinc-manager

Once it has installed, copy and paste the following into the client:

Boinccmd --lookup_account email passwd

With the email and password being your normal login details (maintain the spacing).
It will now spit out an account key for you, so now copy this into notepad or something and copy and paste the following command:

Boinccmd --project_attach accountkey

A successful attachment will be signified by a lack of error messages after this.
Now, whenever you type in the following command into the interface:


You will get a list of possible commands, such as viewing tasks etc.

I found that the 8 core, 8GB machine located in the US using Ubuntu 15.10 was the best option (value and ease etc). If you get issues with the BOINC client in the interface, just uninstall using the below command then start again, being sure to look up the commands as per above:

sudo aptitude remove boinc-manager boinc-client

Let me know what you guys think and if you have any issues following the instructions below, I will edit this post to amend any inaccuracies, cos this is awesome! You can also see the machine I created in my computers in my account (instance-1).

I am having exactly the same problem as the creator of this thread! It is requesting GPU tasks from a non-GPU project, but no CPU tasks. I've waited quite a while now for this to change but every time it says 'requesting new tasks for GPU'. This is quite a major flaw is there no way of fixing it? And is it affecting the throughput of Rosetta as a result?

EDIT: I just got some! Still annoying though! it seems like BOINC knows i've had a moan on here so it got it's act together :D

Thanks for all the advice! You were both very helpful

I use Rosetta on my laptop, a 2.4GHz Core 2 Duo, Dell Studio. I just leave the edge of the laptop with the cooling fan hanging over the edge of my desk and it keeps the CPU around 40-50 degrees Celcius. That's running both cores 100% with no change to voltage or clock speeds. Had no issus with the hard drive yet (only had it 10 months) but mikey gives good advice to back it up because it is a risk.

Posted 13 Mar 2009 by FoldingSolutions
If my computer has two cores each running at 2500 Mflops or 2.5 Gflops.

2.5 x 2 = 5.

5 x 60 x 60 x 24 = 432000Gflops. Or 432 Tflops.

And i Have 26000 credits, and the computer earns on average 900 credits in a whole day.

Then 26000/900 = 28.8888 days.

432 x 28.8888 = 12479.9616 Tflops in total :)

EDIT - please note the the "s" on the end of flops is to exemplify the plural, not to mean seconds, which i assume is obvious to most people :)

I take it then that this was on the NT host for Rosetta? I see you encountered the ultimate long-running task there. Ran for 35hrs.

Have any other Rosetta tasks apparently had this occur?

It might help to look at the computer that was actually running this "35 hour" unit! I didn't know they even bothered making operating systems for these :D

I think that is a pretty conclusive and well informed answer.
The t8330 in this laptop has a TDP of 35W (and actually operates quite a bit below that, as anyone who has touched a 40W light bulb could testify to), and a bit of light inference using folding@home statistics and comparisons it actually performs on par with a desktop model of the same clockspeed. The mini-rosetta application is 6MB in size so would obviously benefit from a larger cache, which as Paul says is just used to mask the incompetencies of the slow FSB in current generation Intels. Thanks to all for taking the time to think about this :)

Posted 9 Jan 2009 by FoldingSolutions
I figured it would be something to do with the cache. It is a laptop, and the processor has a 3MB cache. When running two concurrent Rosetta tasks, each task will inevitibly have only 1.5MB of cache before having to defer to memory along the sluggish FSB. I would not have thought this to translate into such a large increase in productivity though. This is not without saying this is a good thing as it avoids overheating issues and means the whole thing runs a bit quieter. While still knocking out a healthy output :)

Nah I made sure it was running at the same clockspeed both times :)

Posted 7 Jan 2009 by FoldingSolutions
i am just curious, because, although i know its not conclusive proof, but the arrow certainly seems to be pointing in the way of one core could potentially do more work than two due to cache and bus issues

Posted 7 Jan 2009 by FoldingSolutions
Keep in mind that when two cores are running, you are counting it as 2 CPU seconds per second of time on your wrist watch.

So, you seem to be pointing to 50 vs 150 credits as being a 3X difference. But, because hyperthreading to two cores is recording CPU time against two tasks at a time, you should expect to see roughly a 2x difference.

So, if 1 core was getting 150 credits for a given WU run length. If I split that one into 2 HT cores, and each earns 50 credits for roughly same WU length, that's 100 credits earned in that time, because I did the same on two tasks at once. So, really, you need to be comparing 100 with 150.

And since both HT threads need floating point operations, they aren't able to run full out the way a single thread can. They also contend for the same amount of L2 cache on the CPU.

So, yes, running with HT active (i.e. 2 tasks at once) will NOT double your credit per hour. And yes, it's a bit unexpected that you didn't earn something more then 150 with two cores active. But, yes, credit between tasks varies significantly and is very difficult to benchmark. You really have to look at about a month of completed work each way to have enough data to draw any conclusions.

it's a C2D CPU - not P4/i7! ;)

Indeed dcdc, so the question remains ;)

CPU-z still reports 3MB of cache when only one core active, if anyone else has the ability to turn of multi-core support and see if they get the same results tht would be useful.

Here's an odd one...

I have a Core 2 Duo laptop T8300. It has 2 cores at 2.4GHz each. When I disable one core in the BIOS then the remaining core benefits from Intel Dynamic Accelaration giving it an extra 200MHz. So it is now 2.6GHz, simple right? 8.3333% faster.

If you look at my results here , look at the results returned on the 6th Jan.
They each receive ~150 credits/WU, these were the ones run in single core mode.
Now look at the ones returned 7th Jan, they each receive ~50 credits. 3 times less, these were run in dual core mode. They are all the same "abinitio_norelax_homfrag" units.
Now is it possible that because the former results had the whole cache and bus to themselves they did far more work per unit. Or is it more likely that because of the problems of the last few days that the credit "giver-outer" has had some health problems?

Well, now I'm downloading 12 big files (from 2.13 to 12.46MB) named "homfragments_????.zip". Hopefully I'll have enough wu's until everything goes back to normal.

EDIT: Done! 12 new WU's and network activity set to "suspended". My other computer will be doing some WCG for now.

I got 5 WU's now. Just keep pressing update, eventually you get something :)

EDIT: slow downloads though!!
