I have given up on the Intel ARC 770 and replaced it with a Gigabyte GTX1660 Super 6GB card. How many seconds does it take to complete a TF on average? If you got that info before giving up on it. ____________ My primes found at SRBase: 40*1017^215605+1 (Top 5000) 18922*111^383954+1 (Top 5000) 19116*24^791057-1 (Top 5000) 4281*880^27069+1 | |

It took 118,000 sec for that 1st WU. The next one finished in 3680 sec though. EDIT: That 118k is a guess. I do not see 2 TF Valid WU's. The valid WU's usually purge after 24 hours so maybe the 3680sec reported IS the long WU and only the last hour of CPU time after a BOINC suspension is showing. See my question below... The current is at 12 hours and still going. My electric company has put me on a peak/off peak plan where it's 4 cents/KWh offpeak and 31 cents peak (6am-8am and 6pm- 8pm weekdays). So I've had to pause all electronic devices, including BOINC, 6-8am and 6-8pm (which is it's own issue since BOINC doesn't support 2 pause periods per day; have to manually pause the GPU hosts daily until my lazy butt gets around to doing 2nd BOINC data folders). 1) Is the vast discrepancy in run times related to TF restarting from the beginning after a suspension period? 2) Are the WUs TF CPU times only showing the amount of time after a BOINC Time Of Day suspension? (As in 3600sec of an actual 34 hour run) 3) Should my NVidia 1060 run only 1 WU at a time instead of 4 if the suspensions are an issue? ____________ My primes found at SRBase: 40*1017^215605+1 (Top 5000) 18922*111^383954+1 (Top 5000) 19116*24^791057-1 (Top 5000) 4281*880^27069+1 | |

1. there is a checkpointing every 120s then its minimal 2. CPU time is overall 3. yes | |

I have given up on the Intel ARC 770 and replaced it with a Gigabyte GTX1660 Super 6GB card. 1h23min on my RTX500XT, in the current range a GTX1660 should take 25min | |

2. So, how did the UHD on the 8250U complete a TF in 36xx secs (normal is 100k+)? There is a checkpoint in the algorithm that can determine that there is no possible prime in the remaining data set and the WU ends prematurely? Or I found a prime on the UHD! (lol) 3. I'm compiling a data set of 4 TF and 1 TF at once. Will report back the results in couple days. Sorry, I have no ARC to test upon. Currently the 1060 at 4x WU is putting out 4.45 credit/(CPU+GPU sec). I control the GPU clock/power and the room temp for these tests. (BTW, running the TF on the UHD is for WUProp hours. At least it does beat the deadline and get credit. It's only other project is Einstein, AFAIK.) ____________ My primes found at SRBase: 40*1017^215605+1 (Top 5000) 18922*111^383954+1 (Top 5000) 19116*24^791057-1 (Top 5000) 4281*880^27069+1 | |

for point 2 this is a wrapper issue where the runtime after restart starting from 0, you cant find a prime, TF is only sieving | |

Maybe it was opposite? It found factor at 36xx seconds? | |

Maybe it was opposite? It found factor at 36xx seconds? no, we have only one bitlvl per test. The BOINC wrapper is reporting the runtime, after a restart it is counting from zero. | |

I just thought it found factor and decided not to factor further and report at once. | |

I just thought it found factor and decided not to factor further and report at once. Yeah, if this is the logic then you would find TF's that end much more quickly than others. Maybe that explains my data set so far, unless these are shorter because I restarted the BOINC client. ThrottleStop won't adjust AMD clock frequencies so I've been rebooting to adjust TDP wattages on the CPU. Ryzen Master won't work on my severely stripped down Windows 10 OS. We had drastic temperature shifts the last 2 weeks (-15C back to 12C).

These were all run on the GTX 1060, 4 at a time, same room temperature (within 3 f) and MSI Afterburner settings. So either the shorter runs (6 to 7k secs) are the WU ending when it found a factor or I reset my BOINC client. The runs at 172xx seconds might have been when the CPU was running at a lower TDP/frequency. I'm not sure how much CPU performance effects the TF runs. I'll start the data set from the 4 that completed today and not restart the BOINC client and hold the CPU at current TDP of 40 watts (if the weather doesn't get hot in January again...) ____________ My primes found at SRBase: 40*1017^215605+1 (Top 5000) 18922*111^383954+1 (Top 5000) 19116*24^791057-1 (Top 5000) 4281*880^27069+1 | |

There is nearly no CPU time to run TF on GPU. | |

There is nearly no CPU time to run TF on GPU. If the CPU is starved from 3300 Ghz to 1800 Ghz, I'd think it might have some 5 to 10% effect. I'll test that hypothesis some weeks from now. Of course, it's possible the GPU downclocking from the room getting hotter, caused the 17k run times when 15k is normal today. The main question above was: Do TF's end early when they find a factor so we will see runtimes ending as low as a few seconds to maybe half the normal run time? ____________ My primes found at SRBase: 40*1017^215605+1 (Top 5000) 18922*111^383954+1 (Top 5000) 19116*24^791057-1 (Top 5000) 4281*880^27069+1 | |

There is nearly no CPU time to run TF on GPU. I have removed my last post and checked a found factor result, you are right, the test ended earlier if a factor is found. Thats a bonus too in credits. | |

Maybe I should start a new thread about this since it's not ARC GPU. The 3 WU at once is getting interesting results with several ending quite quickly: 89848291 7 Jan 2023, 14:49:44 UTC 9 Jan 2023, 17:01:16 UTC Completed and validated 641.52 1.27 14000 TF v0.21 (cuda120)
The typical appears to be: 89847929 7 Jan 2023, 14:57:16 UTC 10 Jan 2023, 11:44:51 UTC Completed and validated 10447.65 3.31 14000 TF v0.21 (cuda120)
The 4 WU at once had 10x longer CPU time when Parlea@Home was on the CPU's vs LODA WU's Typical run (4 WU at once) Parlea@Home on CPU's: 89834340 6 Jan 2023, 8:43:36 UTC 8 Jan 2023, 13:56:58 UTC Completed and validated 15232.17 128.64 14000 TF v0.19 (cuda120) Typical with LODA on CPU's: 89848299 7 Jan 2023, 14:45:49 UTC 9 Jan 2023, 2:41:13 UTC Completed and validated 15036.94 6.58 14000 TF v0.21 (cuda120)
I'm not sure what happened to this one; it's CPU usage is severe: 89833841 6 Jan 2023, 7:44:22 UTC 8 Jan 2023, 11:19:22 UTC Completed and validated 15971.15 2114.92 14000 TF v0.19 (cuda120)
Since the runs can end soon with early factor found... that means my data sets will need to be larger. ::sigh:: ____________ My primes found at SRBase: 40*1017^215605+1 (Top 5000) 18922*111^383954+1 (Top 5000) 19116*24^791057-1 (Top 5000) 4281*880^27069+1 | |
