Hello, My last WU was terribly slow : https://sech.me/boinc/Amicable/workunit.php?wuid=27300137 Both elapsed time and remaining estimated time were increasing. The completion percent increased very slowly. I was at 25,948 % for a few minutes, with elapsed 4:17:10 and remaining 12:14:10 approximately. It is an mt task : https://sech.me/boinc/Amicable/result.php?resultid=62973424 opencl_nvidia tasks in parallel work fine. It seems to be the same bug than previously: amicable_checkpoint file was corrupt with content: 0 0# I cleaned amicable_checkpoint and other files. And restarted it. But after one hour is was still at less than 3,5 % with completion estimated in 6 days. I stopped my computer, and restarted later and completion was back at less than 0,5 % ! I don't know what is wrong with this WU, but clearly it could not be computed on my laptop for an unknown reason. I had to abort it and switch to another. Someone else had error on it also : https://sech.me/boinc/Amicable/result.php?resultid=62967700 It may be useful to have a look at it in detail. Best regards, Laurent Lyaudet |

Hello, I had again a really slow WU but on GPU this time (opencl_nvidia). This is my record so far. https://sech.me/boinc/Amicable/workunit.php?wuid=27620016 /from 2^2*5*11*67*367*1237 /to 2^2*5*11*67*367*1303*21851 /task_size 30201578225 Total time : 18,423.51 CPU time : 350.37 Usually on my laptop a GPU task takes 10 to 15 minutes at most 30 minutes. But this one took 5 hours 7 minutes and 3 seconds. That's 10 times slower than a rare slow task on GPU and 30 times slower than a somewhat common fast task. If something could be done to make this task faster, it would be great :) Best regards, Laurent Lyaudet |
