most likely you'd still get credit since the WU's need to be resent and will likely take at least 12.5 hours and however much extra time waiting to be run.

Just in case I missed that, aren't there any ARMv6-compatible third-party-compiles for Android (specifically, S@H)? NativeBOINC for Android on my Samsung.

Your CPU seems to be the same type as mine. Just a bit faster.

I had issues initially with getting NativeBOINC to use the apps they made for it, but eventually I got Primegrid to cooperate. Now I'm working on a MW task. Hopefully it goes well.

[...] but eventually I got Primegrid to cooperate.

Didn't work for me, in lack of some matching science app.
"Message from server: Your app_info.xml file doesn't have a useable version of PPS (LLR)." However.

Now I'm working on a MW task. Hopefully it goes well.

I'm halfway through a 34-hour-MilkyWay task (29604 GFLOPS on a 800 MHz ARMv6 without *any* Caches).

Sometimes it can be finicky about downloading the application. I had to attach to MW 6 times before it would get the app. I'm pretty sure it is getting the app form the NativeBOINC devs site. I'm not 100% sure, but I think it might have finally worked when I disconnected the USB cable form my phone. Which doesn't make a lot of sense. As I have it set for "charge only". So the SDCard doesn't get unmounted or anything.

At 65.8% I'm estimating my total CPU time will be around 31.6 hours.

Based on what I was seeing with the primegrid tasks these ARMv6 CPU at 600-800mhz would probably be able to return Seti@Home tasks in time. As the deadlines are sufficiently long. Now they just need to bang out an app for I need to see if I can get the app form that Ubuntu release to work.

When i open it, I have to configure it to a new host, and I have no clue as to how to do that. I was wondering if anyone here knows what to do?

It is asking for Host Nickname, Address and password, using port #31416

There are two answers in the Milkyway thread, check if that helps you.

Thanks :)
I don't have anything that says to log in on an existing account.
It asks for Host nickname, Address, port (31416) and password. Nowhere (and I have pressed all the buttons it has) is there a place for me to log into something. I even used the address that shows up on the bottom of my client's advanced view, no workie.

*is stumped*

Who interesting can look at 2 my new hosts here (@PrimeGrid project):
http://www.primegrid.com/hosts_user.php?userid=49371

One of them is ViewSonic G-tablet and another one Samsung Galaxy mini GT-S5570.

Both running Gingerbread Android OS and NativeBOINC.

G-Tablet's performance look resonably good, it even has 2 CPUs.
Galaxy mini smartphone much slower. I doubt it can finish task before deadline, will see.

But BOINC is running on it too so it quite available for non-CPU intensive projects.


All thanks for Android OS port go to matszpk. Binaries and sources available at his Github repository: https://github.com/matszpk/native-boinc-for-android

EDIT: 1% took 1h48min on G-Tablet, >3h on Galaxy mini and ~0.9% only

I'd try the following:

1. Attach to Milkyway or PrimeGrid with one of your PCs (with very low cache, if you don't want to crunch that on your PC) to create an account.

2. As host nickname you can probably choose whatever you want (of course nothing "complicated", single word only), adress I *think* is the e-mail adress you use for BOINC and password is your BOINC password.


@all: is there BOINC for (jailbreaked) iOS? I couldn't find anything useful so far...

My phone has the same 600MHz CPU as one of your devices. I was not able to complete a Primegrid task in time with it. Milkyway it was able to do reasonably well. It actually ran faster than the PIII 850MHz machine I ran to compare.

I would guess that 1GHz+ ARM CPUs would realistically be required to run the work for Primegrid & Seti@Home. I am looking for my new phone to be something like quad 1.4GHz. :D

I wonder if they will produce a binary for Seti@Home or if the one that was made to run on Ubuntu would work.

It was mentioned that someone was working on it, but no mention of who it might be. Even if they can't get it into the App Store they could release it I suppose.

The beauty of smartphone crunching: your GPU still can do tasks blazingly fast, but some of them will go in addition. No one argue to replace GPU with smartphone AFAIK, smartphones just small nice addtion to BOINC farm :)

I would imagine the Performance Per Watt is very good. As I was not only able to run tasks, but charge the battery from a 2.5w USB connection.

If you want to mess about with low power computing why don't you get a $30 Rasberry Pi? Rather than devote $500+ cellphone to crunching you can power one of those boards off a wall-wart, drawing a couple of watts, with no cooling issue etc.

http://www.raspberrypi.org/

Similar ARM CPU, runs Linux off a SD card, has USB, Ethernet, video out etc. It's a proper little PC.

And this is another wrong assumption that appears in this thread quite often.
Maybe someone will buy smartphone for crunching, but most people buy smartphones and tablets for something another. For example, I bought smartphone for GPS navigation. But when I already have Android-based device, why not make additional benefit from it and turn it into BOINC host? It's whole BOINC initial idea behind this - to use spare and already available resources.
Later some of us (actually, perhaps most who write on this boards often ;) ) got too addicted with BOINC to buy new hosts just for it, as before some bought PC just for gaming...

Question to those who already played with NativeBOINC some time:
currently I tuned it to max performance - devices don't switch off their displays, just turn off backlight. I would like to get them to switch off screens completely - but will this automatically lead to CPU freq downgrade? That is, will crunching with switched off display be slower?
Also, what will be if I short press Power button - do devices go to sleep and stop crunching at all (as netbook does in suspend/sleep state for example) or they will continue crunching with downclocked CPU or even w/o CPU downclock but just with switched off display/graphics? (last case can be even faster actually!).

Probably different with each device. If I press the button on my phone to turn off the display it does seem to slow down the CPU even though I set the option in NativeBOINC to prevent doing so. Otherwise it would dim my display but not completely shut off the backlight.

+1 Hal, it's going to be hardware specific on a per-device basis. You would need to hack firmware to change things like that...

Well, I did some test on G-Tablet.
All this based on assumption that PrimeGrid task progress is linear (don't know if it's true or not).

First 3 h tablet worked with dimmed display, next ~2h it worked with switched off display (power button was short-pressed)

For "display on": both cores give 0.01%/min progress.

With switched off display both cores give 0.011%/min and 0.0115%/min

So, looks like no slowdown and maybe even speedup.

But this should be repeated few times on different WU stages to be more or less sure.

Will leave GT-S5570 in dimmed screen state for night and see how linear progress is. For now it looks like some acceleration present in %/min ratio.

+1 Hal, it's going to be hardware specific on a per-device basis. You would need to hack firmware to change things like that...

I would imagine it could be changed in software. Something like the power config stuff in windows.

Once I get a new phone I will be more willing to hack up my current one. However I still need it to do things like "be a phone". If I found a tablet with a good enough CPU cheap I might consider getting one. As I could use it for things like VNCing into my HTPC w/o turning on my TV and such.
