Today 126 liter/m2 rain hit my town. And we still have to rain days in front of us :)
Average for all December we have 120 liters of rain. So in one day we pass average per month :)


That is quite a lot. (It is what we would call either 126mm or 5in) I don't have the figures for here but I do for the other side of London. http://nw3weather.co.uk/wx12.php . I'd guess we typically get a little less since our usually weather comes from the west.

If I read this right you got 5 inches of rain in one day? Flooding? That is a lot of water.

Running SGS now.

Rough averages are:
5950: 435s
3950: 505s.

Once I adjust for clock speed (4020 vs 3760) the 3950 time comes down to around 470s.
Which gives us roughly a 10% ipc improvement.


SGS are hard on your system... but fun

I know you said a one time post but was just curious as to how many double checked near finds have been found - I know they are not going to show up so was just wondering.

Also, according to those stats I'm currently 69th. Nice.

Nice !

With over 64,000 results already in the database as per the project status page, we are already past 1% of the 4.6 million work units available for this project. Fingers crossed it does not become a rat race and a project which ends way too soon.

Some very revealing stats: https://stats.free-dc.org/subproj/pgrid/WW.

Well there will be some drop off during the next challenge I predict :)

With LLR2, you don't have to worry about being "the prime finder". :)

Man I keep forgetting about that super cool change !!

For some time now I have been running PPS-MEGA tasks on my computer which usually take 65-95 minutes to run on two CPUs. However, when I checked my completed workunits over the past week or so, I noticed several workunits with runtime of 20 minutes, or even as low as 5 minutes. These are full-length tasks (43k+ gflops), and not short DC tasks.

Upon further investigation, I realised that when my computer goes to sleep after several minutes of inactivity, the computing will cease. When I restart my computer, the run time is reset, so if the task has been running for an hour before the computer goes to sleep, and after restarting takes another 5 minutes to complete, the run time will be reported as 5 minutes, instead of the accurate value of 65 minutes.

I just want to check if this may cause any problems with the prime finding? If the first 60 minutes of work are not recorded, may this error cause the programme to miss any primes?

There are folks that have a lot more knowledge about this but a couple of things. 1) if you allow your pc to sleep/hibernate and it stops running the task(s) until you wake it back up your chances of being the initial prime finder go way down and 2) when it resumes should pick up where it left off or close to it and as long as it is finished in a valid state will count regardless of the "stats" on runtime.

Cheers Rick

2080 is ~400s. Surprised it's that much faster than a 2060.

Yeah my 2080's are running about the same - 412s ish... but the 2080 Ti is in 340s ish range.. big difference and I have all the cards running at their stock speed (well whatever was set on "default") no over clocking...

Hmm... CPU units running 2 cores look like they're around a day each... best to stick to GPU for this one I guess.

Yeah but in a pinch cpu can be counted on
