Thank you guys, great work over all these years. Still my favorite project. Good luck in future events.

Very cool.

Wow, I need to start getting lucky and find some primes so I can get on that list.

Working on my last two bronze badges (that can be upgraded).

Side question;

Will there be android Work Units again?

Great discussion, good to see a more level set up. I noticed a few of mine changed, but not sure from what as I didn't have a page open from before the change.

"WUProp badge"

You mean there's a badge out there I am not aware of yet?

Yes, check out the WUProp site for info. Too much to explain in a single post. But essentially total hours per sub-project. Need 20 sub-projects with 100 hours to get the first WUProp star badge.

Again just to point out I wouldn't have all cores going for heat reasons, unless you can maintain your phone being in a cool environment e.g by a cool window. Also do not process while charging - this is 'twice' the load on the battery + will shorten the lives of everything even more.

If processing on just battery, you are looking at VERY short crunching time before you have to plug in the charger. Means a great deal of baby sitting and even less actual credit return. I will try to back off one core, just downloaded the app suggested above.

It would be nice if more sub-projects were available, such as the smaller ones that don't need huge power or mega run times to complete.[/b][/b]

Except for the two sieves, every other PrimeGrid BOINC project is going to A) REQUIRE double-precision floating point hardware, which I understand is not present in all ARM processors, B) will likely run significantly HOTTER than the sieves, and C) in many cases will be longer tasks than the sieves.

Both LLR and Genefer are almost entirely dependent on double precision floating point for the entire calculation, so all of those projects can't run on a processor that doesn't have it.

The Sieves are the easiest tasks here, and run much cooler than either LLR or Genefer, which are essentially CPU torture tests. Very few apps run a CPU as hard as those programs.

Furthermore, while the length of an LLR or GFN calculation is dependent on the number being tested, and can't be changed, with a sieve, the tasks can be made as long or as short as we want.

For those reasons, sieves are clearly the best PG application to run on a phone or tablet. Since the PPS-Sieve is primarily crunched on GPUs, those tasks are much longer than the TRP Sieve tasks, which are only run on CPUs. This make the TRP sieve the better choice for a phone or other mobile device.

In other words, if you're running TRP Sieve on your phone, that's absolutely the best PrimeGrid application for your device.

Thanks for the reply. Are there other Sieve sub-projects similar to TRP that could run on the phones?

I have been running TRP Sieve on my single core HTC Thunderbolt and my quad core HTC DNA.

There are a number of projects available to crunch on NativeBoinc. The projects I participate in outside of NativeBoinc are Asteroids/MW/PG/SETI/WUProp. So my experience is only with those projects on the phones.

So far, I have not gotten any SETI WU's on either phone, so it is out of the discussion for me at the moment.

Of the projects running MW/Asteroids/PG (& WUProp), PG's TRP Sieve, by a noticeable margin, hotter then the other projects. Credit wise, due to WU run time and obvious processing power, along with only running while charging on a strong charger, the credit return is not much.

But for the WUProp badge people, and those who can monitor the heat, it is not bad for a little extra credit. It would be nice if more sub-projects were available, such as the smaller ones that don't need huge power or mega run times to complete.
