Congratz!

Nice, thanks!

Just a little correction.
Maybe it should be 500M, 1G, 2G...
because we have Giga after Mega, not Tera. ;)

I have never had a neverending task, maybe something is blocking your results file.

It's not my computer to have never ending tasks. I've got (and aborted) resends. I was the wingman.
Those resends are useless imho.

It's still happening.


@rebirther: maybe you should avoid to resend these tasks if you are not already doing so. I aborted 45 tasks from my work queue. We have a residue and doublechecking is not our purpose... so it's useless to crunch them again.

I link them here so you can copy residues.
28686860, 28688798, 28685897, 28689205, 28686861, 28685584, 28687739, 28687993, 28688572, 28685593, 28685826, 28688283, 28687983, 28688262, 28688971, 28688241, 28688902, 28687770, 28688223, 28688294, 28685528, 28688293, 28687125, 28685519, 28688222, 28685893, 28688295, 28688299, 28687831, 28688147, 28688472, 28688340, 28688510, 28688235, 28688548, 28688274, 28688377, 28687850, 28688246, 28687838, 28687968, 28686146, 28687155, 28687078, 28686807

If you can't fix that, I could try to implement something to retrieve residues of this kind of errored tasks. It would mean to scrape thousands of html pages though. Let me know.

@bluestang

Anyway you can copy your results from boinc directories before they get uploaded to the project server. Not very exciting though because those factors are not rare numbers. Remarkable numbers are tracked by admins.

If we can maintain this firepower, going all the way to 74 bit by the end of the year is indeed feasible and going all the way to 76 bit next year is feasible. With that kind of work being completed at the moment, it is best to go like Rebirther prefers and go breadth first - that will give those with slow GPUs a chance to adapt to the near future, where everything with a factor below 75 bit is cleared.

Don't forget that hardware improves and better GPUs will come here. ;)

Collatz is the worst example. Making credit like collatz will attract all the point whores and cheaters.

Ahaha! +1


Collatz is inflated.

by a factor of 1.527 - this is roughly what I'd expect, perhaps as high as 1.6 to match PPS Sieve and Moo credits (based on what I remember !)

I would set TF daily credits a bit lower than PPS-SV ones so that we'll get only users that are interested in science here.

Not worth running it at those rates, unless someone just loves this project.

Me. :)

Rebirther, maybe you should write on News when you increase TF exponent.
77-78 are very long on my gpu (GTX1060).
10) Message boards : Number crunching : Tiny elapsed/run times (Message 5632)
Posted 23 Jan 2020 by Luigi R.
First of all, I'm not restarting BOINC.

Some WUs have correct elapsed time and tiny run time.
E.g. R510_200-250k_wu_2872_1
I guess there is nothing wrong here.

Some WUs have tiny elapsed time and tiny run time.
E.g. S177_retest2_wu_119_4
3.04 seconds elapsed, 0.09s seconds run.
3 invalid tasks before mine that is valid.
Is this ok?
11) Message boards : Number crunching : No checkpoints for long3 (Message 4994)
Posted 27 Feb 2019 by Luigi R.
nope.
time scince last checkpoint: 1hr 44m 53sec
cpu run time: 1hr 44m 53sec

This is what BOINC says. You are talking about numbers that are not correct.

You must see stderr.txt on your slots directory, as rebirther said, that it's not where BOINC gets its numbers.


If you think it's not like that, try to restart BOINC when work is complete at 95% when you get a smaller wu (e.g. 20-minute wu). You will see restarted work is completed within a couple of minutes.

Ok, no problem. Why do you do manually?
13) Message boards : Number crunching : Little primes (Message 4963)
Posted 17 Feb 2019 by Luigi R.
I'm tracking lresults.txt content for curiosity.

I noticed that I discovered some little primes (~40k digits) while crunching these small S3_80-90k tests.
What about the "paternity of discovery"? :D
Will I be inserted here (first post)?
14) Message boards : Number crunching : SR-base overheat !? (Message 4898)
Posted 23 Jan 2019 by Luigi R.
What frequency have you tried?
Disable Turbo Boost.
Disable Hyper Threading or use 50% CPU.
Run 4 tasks, but...
Start from 2.0GHz and increase by little steps till you reach 70C.
Tjunction for these chips is around 98C, so don't worry.
Leave that frequency and good crunching!

P.S. My i7-4770k @3.5GHz is getting 70C with TB off. If I decrease frequency @2.1GHz, temperature drops to 50C. You should observe something similar.

Posted 22 Jan 2019 by Luigi R.
If you run SR alone, you could set a lower frequency leaving the CPU at 100%.
16) Message boards : Number crunching : Check points (Message 4465)
Posted 18 Jul 2018 by Luigi R.
Checkpoints are every 10min, see FAQ. Time will not be saved after restart BOINC/Computer.

So it's just a BOINC bug, but llr64 resumes from the last checkpoint after restart, right?

Select the shorter tasks if you are going to switch off or re-boot your computer.

Why? I'm not sure work is lost if you shutdown your system.
