1) Message boards : Number crunching : Um, Got a Couple of Whoppers? (Message 1459) Posted 16 Nov 2020 by bryan Post: I've got some big ones too - cancelled a few, but one that got done took 2 days https://sech.me/boinc/Amicable/result.php?resultid=35476847 My usual runtime is around 2 hours.

2) Message boards : Bug tracker : GPU WU's using a lot of CPU on Linux? (Message 1381) Posted 18 Apr 2020 by bryan Post: Oops.. looks like having it set at 16 makes it not work as well. Changing it to 19 or 20 helped, but brought machine to a crawl.

3) Message boards : Bug tracker : GPU WU's using a lot of CPU on Linux? (Message 1380) Posted 18 Apr 2020 by bryan Post: I looked at these two recently completed WU: https://sech.me/boinc/Amicable/workunit.php?wuid=13407446 https://sech.me/boinc/Amicable/workunit.php?wuid=13407136 https://sech.me/boinc/Amicable/workunit.php?wuid=13403818 My computer is the one spending an order of magnitude more CPU time on them. The last one and I have the same video card. I'm guessing it could be a Windows vs Linux bug? (Although mine shows NVIDIA GeForce GTX 1050 (1977MB) driver: 440.64 OpenCL: 1.2 vs theirs NVIDIA GeForce GTX 1050 (2048MB) driver: 442.19 OpenCL: 1.2) I have Kernel size for NVIDIA GPUs set 16 but definitely still get UI lags when it's using GPU (but quite randomly likely related to it using the CPU at lot).

4) Message boards : Bug tracker : GPU work units restart from 0% every time I touch my computer (Message 1202) Posted 6 Oct 2019 by bryan Post: My understanding is the GPU workunits are not very useful at this point - I have disabled them.

5) Message boards : Number crunching : Countermeasures for Increased CPU Time (Message 1034) Posted 16 Dec 2018 by bryan Post: My guess would be the rig that doesn't work has show file extensions turned off. So it ends up being .xml.txt or something... Just a guess.

6) Message boards : Number crunching : Amicable Numbers has slowed down (Message 968) Posted 2 Nov 2018 by bryan Post: Oh, if that bottleneck may be happening in primesieve the new versions has some more tweaks for that - (although last time they didn't have a noticeable impact) https://github.com/kimwalisch/primesieve/blob/master/ChangeLog Specifically 7.1: primesieve-7.1 runs up to 30% faster on Intel Skylake-X CPUs! The default sieve size is now (L2 cache size / 2). Using a sieve size that is slightly smaller than the L2 cache size reduces the number of L2 cache misses which improves performance on CPUs with slow L3 caches. primesieve-7.1 will also run slightly faster (< 3%) on most other Intel CPUs. Aside: is primesive used on OpenCL? I see that hasn't been updated on that branch for some time.

7) Message boards : Bug tracker : Amicable Jobs not throttled? (Message 967) Posted 2 Nov 2018 by bryan Post: Noticed this post on the Boinc project site - https://github.com/BOINC/boinc/pull/2789 Either way this outcome may impact this project.

8) Message boards : Number crunching : Amicable Numbers has slowed down (Message 963) Posted 31 Oct 2018 by bryan Post: The applications were last published in September https://sech.me/boinc/Amicable/apps.php You can see how long they are recorded to take at Tasks here https://sech.me/boinc/Amicable/home.php , and then see if there is an increase. The only thing I've noticed is the number of new discoveries has for me, been non-existent for a time- explained in another thread.

9) Message boards : Bug tracker : Amicable doesn't respect usage limits (Message 886) Posted 21 Aug 2018 by bryan Post: On Linux I suggest installing the sysfs package so you can set ignore_nice_load [1]. Unfortunately even a fully niced process will be able to crank the CPU up. [1] https://www.kernel.org/doc/html/v4.14/admin-guide/pm/cpufreq.html

11) Message boards : Bug tracker : Not getting GPU workunits (Message 807) Posted 29 Apr 2018 by bryan Post: NNT? Just updating the project didn't help. I forgot to mention I'm running a fresh install of Ubuntu 18.04.. whoops.. No_Alt_Platform in config. I also tried resetting my web preferences in Amicable and my local ones. Decided to try adding the two projects I had on previous install.. Einstein and WCG.. didn't help, but Einstein didn't get a GPU workunit either... and they automatically gave me a log (https://pastebin.ubuntu.com/p/KZbkZsXbDp/) I can login to see why: 2018-04-29 02:18:20.3951 [PID=29417] [debug] [HOST#12590263] MSG(high) No work sent 2018-04-29 02:18:20.3951 [PID=29417] [debug] [HOST#12590263] MSG(high) see scheduler log messages on https://einsteinathome.org/host/12590263/log 2018-04-29 02:18:20.3951 [PID=29417] [debug] [HOST#12590263] MSG(high) Binary Radio Pulsar Search (Arecibo) is not available for your type of computer. I stopped BOINC and apt installed nvidia-opencl-dev libgl1-mesa-dev mesa-common-dev ocl-icd-opencl-dev opencl-c-headers clinfo, and then Einstein@Home immediately filled up the nVidia jobs. (I installed clinfo first and gave output indicating everything was fine, but obviously not..) I also decided that installing nvidia-cuda-dev might get it to work for Amicable, but will see after some of the E@H jobs finish.

13) Message boards : Bug tracker : Not getting GPU workunits (Message 802) Posted 27 Apr 2018 by bryan Post: I've still gotten GPU tasks with that set before. I just turned that off in the project and locally and still got 0 tasks.
