| 1) Message boards : GPUs : AMD GPU Windows 10 21H1 Computation Error
Message 104309 Posted 5 May 2021 by karlfoley |
I may have spoke too soon as these initially worked, but then stopped working again, but this time failing at the end instead of the start. I did have the AMD GPU disabled in BOINCstatsBAM! for both WCG - Covid 19 and Collatz Conjecture but still kept getting them and them erroring. I have disabled the AMD GPU for both projects now with the following cc_config.xml: <cc_config> <options> <exclude_gpu> <url>https://boinc.thesonntags.com/collatz/</url> <type>ATI</type> <app>collatz_sieve</app> </exclude_gpu> <exclude_gpu> <url>http://www.worldcommunitygrid.org/</url> <type>ATI</type> <app>opng</app> </exclude_gpu> </options> </cc_config> |

OK, reinstalled the AMD GPU drivers for the 4800U from the AMD website and now all appears to be working again. Looks like the upgrade to 21H1 screwed up the GPU support somehow. Downloaded drivers v21.4.1, which installed Display Driver v27.20.21002.112 so it was an upgrade from the drivers installed before the upgrade to 21H1. |

Boinc version: 7.16.11 GPU is embedded in AMD Ryzen 7 4800U laptop. GPU driver v27.20.11032.6002 I've tried multiple reboots and any CUs available for 21H1 have been installed. Here's the log from a Collatz grid failed WU: 02/05/2021 06:39:29 | collatz | Starting task collatz_sieve_10d19ad5-1596-440a-a8df-a910079027ff_0 02/05/2021 06:39:33 | collatz | Computation for task collatz_sieve_10d19ad5-1596-440a-a8df-a910079027ff_0 finished 02/05/2021 06:39:33 | collatz | Output file collatz_sieve_10d19ad5-1596-440a-a8df-a910079027ff_0_r1617770302_0 for task collatz_sieve_10d19ad5-1596-440a-a8df-a910079027ff_0 absent |

Since my computer upgraded to 21H1 AMD GPU units for both World Community Frid - Covid 17 and Collatz At Home have been failing with "Computation error". World community Grid ones fail at the end but Collatz Conjecture ones fail a few seconds in. |

Just out of interest, I benchmarked my laptop before and after the OS+BIOS patch for meltdown. Before: 04/01/2018 16:52:28 | | Running CPU benchmarks 04/01/2018 16:52:59 | | Benchmark results: 04/01/2018 16:52:59 | | Number of CPUs: 4 04/01/2018 16:52:59 | | 3589 floating point MIPS (Whetstone) per CPU 04/01/2018 16:52:59 | | 11323 integer MIPS (Dhrystone) per CPU After: 15/01/2018 15:31:35 | | Running CPU benchmarks 15/01/2018 15:32:06 | | Benchmark results: 15/01/2018 15:32:06 | | Number of CPUs: 4 15/01/2018 15:32:06 | | 3433 floating point MIPS (Whetstone) per CPU 15/01/2018 15:32:06 | | 8509 integer MIPS (Dhrystone) per CPU Floating point appear to be down around 4%, but integer is down around 25%. I would guess floating point has more of an impact on BOINC than integer? |
