In the very near future (probably tomorrow later today UTC) we will be turning on the work generator for the Cullen Woodall sieve.
Apps are available for the following:
* Windows 64 bit Nvidia OpenCL GPU apps
* Windows 64 bit AMD OpenCL GPU apps (new)
* Windows 64 bit Intel OpenCL GPU apps (new)
* Linux 64 bit Nvidia OpenCL GPU apps
* Linux 64 bit AMD OpenCL GPU apps (new)
* Linux 64 bit Intel OpenCL GPU apps (new)
The GPU apps should, for the first time, work well on iGPUS.
At the present time, there are no CPU apps and no Mac apps.
The current sieve file ends at n=25M and the new sieving will create a sieve file for 25M < N < 50M.
If you want, you can select CW-Sieve right now in anticipation of the first tasks becoming available.

If this is using my code, then I can provide an Intel Mac build, but I don't know if this is tightly integrated into BOINC. In other words I don't know if it has to built using BOINC headers and libraries. I can also provide an M1 Mac build using OpenCL, although I haven't tested it. I haven't finished the changes to support Metal as it has not been a priority.
IIRC the previous sieving work was done with ppsievecl, which might be faster. |

Awesome news and developments.
Thanks to the programmers and everyone else involved. |

Michael,
I am temporarily running PPS Sieve. Do I select both CW Sieve and PPS Sieve so as not to have my GPU's idle waiting for the CW Sieve to be officially available or does PG have a default GPU app anyway? |

Yes, you should select both.

Noice. Just set my 2 big GPUs to get going once it's live and get that dangling old Ruby up to something fun.

If or when CPU applications are available I can upgrade my Silver badge.
Just have to wait. I am fairly good at waiting.

No CPU support for this project. GPU only. |

Gents,
CW Sieve tasks are now available for download. I just got my first units ..... BOINC estimates a much longer run time than I would have expected but it means very little at this point and until they start to process. |

It is possible that pending credit for the CW sieve may show incorrectly. This will be corrected in the next couple of days.

I've had just one task validate successfully. Many others are in pending state. The floodgates have definitely opened. It will be very interesting to see how fast we make progress.

Yes, my dual 570s puttered out depressingly close to the next badge when the project was winding down many years ago.

What work is necessary to create a Mac app? Does new code need to be written or is it just a compilation job?
____________
1 PPSE, 5 SGS, and 5 GFN-15 primes |
|
|
|
|
|
How can we tell how fast we are making progress apart from the speeds that we return tasks at? I am thinking it is something to do with the numbers in the task name, I don't know how to read them to see how far along we are
Will be interesting to see how long the subproject lasts |

Compilation. Program depends on external library "primesieve" which must also be build separately.
For new developers which never did anything for Boinc earlier, biggest problem will be building Boinc libraries. |

For now, only the factors found in the original search are search are shown on that page. The new factors are kept elsewhere. I will see if it’s possible to display them information on the new factors. No promises.

At least for now, the display of factors has been removed from that page. The information isn't easily available.

My run times seem to have dropped by just under 10%. Has anyone noticed similar behaviour?
I am not complaining given that I am using series 10xx GPU's. |

I have noticed similar on my Radeon 7900XT
The first few tasks I ran averaged out to 930s and now they's around 790-800s

As P increases, the program can iterate from N = 25M to 50M in larger steps. Also, the density of primes decreases with higher P range, resulting in a reduction of time to complete a constant range of P. |

I'm unsure of the size of these wu's. Is everyone just running 1 at a time?
If not, is there a app_config file to increase to 0.5 (2 wu's)?
Edit - I think I see the answer. 1 wu runs at 100% and pulls quite the draw on a 4070Ti. (240W)
Ouch.

What are the odds of getting a CPU application, like we had when this sub-project was last run (I am pretty sure it was CPU as well). just asking as I have no GPUs and currently only have CPUs to use.

Hey conan,
If I remember correctly, the CPU app is very, very inefficient compared to the gpu app. So inefficient it's more efficient to use the iGPU for the first time for primegrid. You're i5-4460 can run it on the iGPU by selecting the intel(any) box, it can still run cpu apps at the same time. It will slow down your cpu tasks a bit though. I'm unsure if the iGPU on your 7900x can be used under the amd selection. I don't believe it can for now, I know the Ryzen ####G sku's can though.
Edit: I've been told regular ryzen 7000's igpu should work by just selecting amd gpu, however I don't have one to test myself. |

G'Day Dirk,
Thanks for the reply.
I hadn't realized that the i5 had an iGPU but now I look at the machine I notice that there is no video card, and video must be coming from somewhere for my display.
The Ryzen 7900X however I did know had one as it is shown in my OS, I also have an old (though sold new with this machine) Nvidia GT 730 (I think) that the computer builders put in when they built it (built for a price).
Alas BOINC does not detect any video devices on any computer I run, I run Fedora Linux on my main computers all fairly late versions, so CPU all the way for me.
Oh well worth a try, at least I have the badge, so no real problem there anyway, will just stay silver.
Thanks again
Conan

According to my badge for this project beside it when you hover the mouse over it has got "(suspended)" I am sure this is just a cosmetic issue. Hopefully when/if this is sorted credits will added to the badge
Boinc manager is currently estimating it is going to take 9 hours 22 minutes and 3 seconds to complete a task, tasks are taking about 9 minutes and 37 seconds on my 3080. These are continuing to keep coming down when I 1st started processing these probably 1 1/2 to 2 weeks ago tasks were taking around 10 minutes. |

Generalized Cullen/Woodall Sieve is the one "suspended".
Cullen/Woodall Sieve is the one that is running and active.

Since I have an "OLD" Intel Graphics 620 processor, and it's not being utilized, I'm running CW-Sieve on it. Yes, CW-Sieve runs, but it takes 36 hours to complete a task. When I ran Manual Sieving using my GPU via Command Prompt, I specified a "B" and "W" setting which sped up the processing:
.
gfnsvocl_w64_2G 16 68060 68061 B13 W1
.
Does anyone know if:
- There are any GPU settings which may speed up my processing,
without "frying" my machine?
- Which GPU settings and at what level do you recommend?
- How do I specify the GPU settings for a CW-Sieve task(s)? |

Can someone running CW-Sv with a 4060 GPU please provide some stats on run times per unit?
Thanks! |

Mike, I did check this list but no reference to the 4060 aside from a laptop unit.
Since the 4060 Ti has approximately a 50% improvement over the vanilla version, I can work backwards and use the data available for the Ti version.
At this point it means very little as I am virtually all set to pull the trigger on an MSI 4060. At 300 euro locally, it is certainly not a budget-breaker. |

No 4060 here, but I have two 4060 Ti Founder's Edition cards. CW-sieve is currently running ~710 secs per work unit on both.

Scott, most helpful as usual !
You are realizing 931k credit per day with the 4060 Ti and which means the 4060 should be around 621k. |

I think you are likely underestimating it a bit. My guess is the 4060 to be around 650k - 670k per day.
