new one: Hozer https://setiathome.berkeley.edu/show_host_detail.php?hostid=8878385 his prime card shows a R9 390, but his secondary card is a 5700XT. also, for AMD cards, it appears that the level of double precision performance is the main/first factor for ranking the cards in BOINC. also interesting, and I just noticed, that the seti apps only report half of the number of compute units on these new cards. 5700's report as 18 CU, when in reality they have 36 5700XTs report as 20 CU, when in reality they have 40 but the older cards seem to report correctly, eg. the R9 390 correctly reports 40 CUs Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

Richard and DA need to update coproc.cpp again to handle the Navi cards by adding code for cores_per_proc = parameter. They had to change the code to properly handle the new Turing cards where the cores_per_proc value was half of Pascal.https://github.com/BOINC/boinc/pull/2707 Looks like they need to double the value for Navi. https://github.com/BOINC/boinc/commit/20af3e90ce165c23edb700ecc21ec729dd36dff8 Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I'm a little hesitant about submitting this change, because I've never personally worked with AMD cards or with the developer of an AMD app. From what I understand, the process for deriving the card geometry from the API is rather different from the NV situation. Also, the only effect of the NV patch I submitted was the correct calculation of GFlops Peak, which helps in runtime estimation - it doesn't affect the actual calculations at all. Having said that, I'm perfectly happy to submit a patch if we can work out exactly what is needed. I can speak with Ray Hinchliffe (author of SIV) to see how he handles those cards: we cross checked the NV results before submitting the last change. I'll also hunt through the Wiki reports, which are usually pretty comprehensive. There may even be manufacturer documentation... ? Anyone? ;-) Edit - the ATI code (and comments) are at https://github.com/BOINC/boinc/blob/master/lib/coproc.cpp#L841 There don't seem to be any 'magic numbers' for cores_per_proc, like we have to use for NV - anybody really knowledgeable about ATI hardware willing to help? |

If it helps, I cross-referenced my recent inconclusives with the list posted earlier and these three are candidates all running RX 5700 hosts that are not yet listed: dcox https://setiathome.berkeley.edu/show_user.php?userid=10884993 iinkabob https://setiathome.berkeley.edu/show_user.php?userid=102908 Simgiov https://setiathome.berkeley.edu/show_user.php?userid=8796082 |

Mr. Kevvy could you check your list please as you have some unclosed tags in it I've just noticed as calendir 9663884 is still using their GPU. Other than the usual culprits 4 new names turned up here. AshlandPony 9004257 cprince1977 10886783 Illyria 10845292 jcr 3428 Cheers. |

From what I understand, the process for deriving the card geometry from the API is rather different from the NV situation. What isn't to say the API itself is incorrectly reporting the number of SM's on the newer cards. After neither Khronos nor AMD has fixed the drivers yet for this threads problem, I wouldn't bet either way. It would be good to check with Ray and see if SIV reports the correct number of SM's or whether he had to modify/fudge SIV to fix what the API reports to jibe with what AMD says the architecture actually has.

I am still keeping my AMD GPU firmly switched off despite regular messages from SETI@home app to fix this! :) I quote: SETI@home: Notice from BOINC Your settings do not allow fetching tasks for AMD/ATI GPU. To fix this, you can change Project Preferences on the project's web site. Thu 09 Jan 2020 16:13:08 GMT Perhaps it would help if SETI@home could send a different notification to those of us who have AMD GPUs until such time this OpenCL issue is resolved.

Just got apprised that AMD released new Adrenaline drivers for Windows 10 today. One of the fixed issues is with Seti@home result overflows. Fixed result overflows that can be experienced with Radeon RX 5700 series when using SETI@Home. https://www.amd.com/en/support/kb/release-notes/rn-rad-win-20-1-1 Need to have some of the known 5700XT users that have responded to PM's give the new drivers a test run.
