Oops!!!

There was an oversight in my SQL. We're almost at the point where our SoB results end, but not quite. It seems we've had a case of "premature celebration!"

Here's the actual numbers:

+--------------------+-----------------+ | Highest N sent out | Highest residue | +--------------------+-----------------+ | 30,728,431 | 30,731,662 | +--------------------+-----------------+


NOW we're really past the end of the known SoB tests:

+--------------------+-----------------+ | Highest N sent out | Highest residue | +--------------------+-----------------+ | 30,732,788 | 30,731,662 | +--------------------+-----------------+

I am using 2 cores for CPU, and all GPU with 0.00947 CPU(???)+1 NVIDIA GPU


You should completely ignore that number. BOINC literally makes it up out of thin air. It does not in any way reflect how much CPU the task is using.

More precisely, that number is NOT a measurement of CPU usage. It's BOINC's guess, based upon its own arcane logic (none of which is based on actual measurements) of how much CPU the task is *expected* to use. It is less grounded in reality than the politicians of whatever political party you happen to be opposed to.

‘The SoB double check has ended’


No, it hasn't. The double check ends at the end of the range SOB was running when it died. We don't know how much of that range was tested. The double check ends at n=31M. Actually, it ends when the last task is done, and that's probably going to be about 6 months after the last task is sent out.

What has happened is that we're now beyond the point that we're 100% certain SOB at least partially tested at some point. Beyond this, until 31M, is unknown.

And then I guess it will take several months until the last active task finishes.


Speaking of. These two tasks in n=28, are they cursed or something? I mean, come on, six weeks -- even I would finish them in this time.


They're computers that are only running a fraction of a day. They'll get there. Slowly.

On one of the tasks, there's two computers working on it (we only need one of them to finish).

This is the first computer:

Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz [Family 6 Model 69 Stepping 1]


That's a Haswell. It's plenty fast. However...

% of time BOINC is running 17.0944 % While BOINC running, % of time host has an Internet connection 94.2974 % While BOINC running, % of time work is allowed 58.4962 %


17% * 58% is 9.9%, which is the amount of the day a BOINC task is running. That's not even saying the SoB task is running; it could be sharing time with SETI or whatever. That's why it's so slow.

It's 79% done.

By comparison, this is one of my computers:

% of time BOINC is running 99.9999 % While BOINC running, % of time host has an Internet connection 99.9941 % While BOINC running, % of time work is allowed 99.9999 %


Can you see the difference?

This is the second computer working that task. It's probably going to finish first, despite being a much older and slower CPU:

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz [Family 6 Model 15 Stepping 11] % of time BOINC is running 34.3889 % While BOINC running, % of time work is allowed 94.8565 %


It's 75% done.

This is the computer working on the other task:

AMD FX(tm)-8320 Eight-Core Processor [Family 21 Model 2 Stepping 0] % of time BOINC is running 24.056 % While BOINC running, % of time host has an Internet connection 99.8162 %


It's currently 85% done.

Guess I woke up at exactly the correct time:

+--------------------+-----------------+ | Highest N sent out | Highest residue | +--------------------+-----------------+ | 30,731,662 | 30,731,662 | +--------------------+-----------------+


Fresh meat everyone! Let's go prime hunting!

Does PG automatically allow the exportation of user stats or do I need to opt in?

AT Hiker


It's automatic.
