See the card in the Host's Detail, but no tasks yet on it. See you are running stock too which means BOINC it going to send you every flavor of gpu app to test. It would go faster if you put the system on the Anonymous platform using the latest Lunatics Installer available at Crunchers Anonymous or Mike's World and select the SoG app for the gpu.

Thanks for the tip. Installed and processing, standby. |

Ok, boys, here's a work unit on the Titan V: https://setiathome.berkeley.edu/result.php?resultid=6236392827 |

And to really make it work, i'd suggest trying these command line values in the mb_cmdline_win_x86_SSE3_OpenCL_NV_SoG.txt file in the project data directory. -hp -period_iterations_num 1 -high_perf -high_prec_timer -sbs 2048 -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64 No need to restart or anything like that. With the values in that file, they will be picked up when each WU starts. I'd let it run for a couple of hours- see what processing times you get for Arecibo & GBT work. With that number of Compute Units available (80! 80 $%$#%# Compute Units!), 2 or even 3 (or maybe, maybe even 4) WUs at a time will probably give you the most work per hour. But let it do 1 at a time for a while just to see what the base line is. EDIT- and did you pick AVX for the CPU when running the installer? That will give the best output from it as well.

Done. Standby for more work units to pour in. This thing is flying through units like no ones business. EDIT- Can't recall if I selected AVX for CPU when running the installer. |

Just look at your task manager to see if the AVX app is running. No AVX is not running, but those setting you gave me cut the time in half for a unit: https://setiathome.berkeley.edu/result.php?resultid=6236430352 |

Card just tanked. May need to reboot. |

Haven't seen any BLC tasks yet, but the times with the suggested tuning parameters for the r3557 SoG app are equalling the compute time for Arecibo shorties that the special app gets in Linux.

Card just tanked. May need to reboot. Watch your temps. Nvidia always is way too conservative with fan profiles to accommodate low noise profiles and sacrifice card performance. The card could have crashed because of high temps or more likely immature drivers doing real compute.

Impressive times & -unroll 80 ????? Does the software even work with that numbers? And that is under Windows SoG, now imagine with Linux & CUDA90. Ready for Hypersonic speeds. You give me another reason to win the lottery. Imagine what a 4x Titan V Linux host could do? Soon, very soon they will need to make changes in the way the work is distributed to feed this new babies. With this times a single Titan V could easelly crunch the entire 100 WU cache 1 - 1 1/2 hrs. |

I guess $3000 went up in smoke, after just a couple of SoG tasks. No, she lives. I couldn't resist it and opened up the other box and just installed the twin brother. I'm going to burn it in with some Ethereum mining and might not have time to run some SETI tests until later tonight PST time. https://drive.google.com/file/d/1Fmo6jLkq88pvMiq29-q_DySbA5UoYPIh/view?usp=sharing |

I that a 760W PSU I see? Might be a tad small ... |

what's you thinking 850? I'd probably go with 1000, overkill I know but.... |

Maybe Raistmer will notice the thread and chime in. My question, AFAIK SBS=2048 is the largest value you can pass in parameter tuning and the stderr.txt shows that. However the stderr.txt also shows 3072 MB actually allocated for the task. Is this a case where the parameters are just ignored and the OpenCL part of the driver simply sets the memory used to be the 25% of the cards memory as has been established in other threads? So 12GB/4=3072 MB. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

The Titan V has a TDP of 250W and the user probably is just letting it run stock with no overclock so I would expect the card to hew to its TDP. So ~500 watts total for both cards plus whatever the Xeon server needs. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

So ~500 watts total for both cards plus whatever the Xeon server needs. So 850W bare minimum to allow for full loading of the GPUs & CPU. Grant Darwin NT |

what's you thinking 850? I'd probably go with 1000, overkill I know but.... Given a switch mode supply is most efficient around 50% of it's rated load, and up to 75% is still pretty good, a 1kW PSU would be just about right. 25% headroom is nice, 15% isn't enough IMHO. Grant Darwin NT |
