Which WUs, can you give a link? Some WUs are longer than others, sometimes many times longer. Thankfully, part 3 WUs are much more uniform, and it will start in about a week from now.

Thanks for the update, Sergei. My RAC has been increasing for ~36 hours. Hopefully, that was the nadir.

Part 3 work units currently running on my Ryzen 5900X currently have been running for over 2 hours each (6 at a time on 4 cores each).
They are only at between 7.7 % and 11.4%, seems to be way longer than before.

PS:: The estimated completion times have blown out to over a day.

Edit: I re-read your post and you wrote "4 threads per WU". This is a multi-threaded application, it can use all CPU cores - you don't need to run many WUs in parallel. I tuned part 3 WUs to take ~2 hours on a 16-core Ryzen 7950X (using all 32 threads). Please note that GPUs are much faster with part 3 WUs (less than 2 minutes on RTX 4090), so CPUs are expected to be slow.

Thanks Sergei, I use what I have as I don't have any GPUs that can do this work.
I have upped my preferences from 4 threads to 8 threads for future work units (I don't think I can update an already downloaded work unit with new settings) and see how that goes.

The following: https://sech.me/boinc/Amicable/result.php?resultid=76449455 took 14 minutes and 15 seconds, is this an acceptable runtime on a 4080?

No, it should've been much faster. Your GPU can complete WUs in ~3 minutes, as you can see from the list of completed WUs, and all part 3 WUs are the same for GPUs. Double check that nothing else is using GPU and that you run 1 WU at a time.

Thanks for the feedback, not all tasks that take that long (as you noted) I will keep an eye on things

Hello it seems there is no GPU task for macOS ?

I can see the apps have been upgraded 3 days ago including macOS, maybe you didn't open the flow for mac because you have no tester ?

macOS OpenCL application works, see for example this task.

The task that Sergei references was completed by my computer <https://sech.me/boinc/Amicable/show_host_detail.php?hostid=214000>. This is an 2018 i5 MacMini connected via Thunderbolt 2 to three eGPUs, each housing an AMD Radeon RX 6800 XT.

The following GPUs running under MacOS have recently completed Amicable tasks: AMD Radeon RX 6800 XT, AMD Radeon RX 6600 XT, AMD Radeon RX 6600, AMD Radeon RX 5700 XT, AMD Radeon Pro 5500M, AMD Radeon RX 580, and NVIDIA GeForce GTX 780.

I have been having trouble with a 2008 MacPro 3,1 with two NVIDIA GeForce GTX 980 Ti GPUs. However, I don't think the problem is with Amicable. I think that computer is reaching the end of its life.

I am very thankful that Amicable continues to support intel Macs with AMD GPUs. Not many BOINC projects do so.

I'm not saying it's not working, I'm saying I cannot get any tasks, my boinc is setup to receive tasks from Amicable, my machine is set on default preferences and only CPU is disabled, GPU is enabled, but nothing.

Dim 14 avr 17:29:12 2024 | Amicable Numbers | Requesting new tasks for AMD/ATI GPU
Dim 14 avr 17:29:13 2024 | Amicable Numbers | Scheduler request completed: got 0 new tasks

It's been like that for almost one week. I had not crunched on Amicable for a long time.

My GPU is

Dim 14 avr 17:28:06 2024 | | OpenCL: AMD/ATI GPU 0: AMD Radeon Pro 5700 XT Compute Engine (driver version 1.2 (Oct 10 2023 22:45:12), device version OpenCL 1.2, 16368MB, 16368MB available, 4797 GFLOPS peak)

it is in the list that Tigers_Dave mentions as having completed tasks, so why can't I get any :(

There are 2 pages for preferences, please check both:
https://sech.me/boinc/Amicable/prefs.php?subset=global
https://sech.me/boinc/Amicable/prefs.php?subset=project

OH MY GOD in the standard preference profile the only available app was... deactivated !! How can this be !! I didn't do this, I swear ! :)

Once (re)activated it's much better ! Thanks :)

Work I processed on 17 May. Some work units complete in 3 minutes or under https://sech.me/boinc/Amicable/result.php?resultid=78865397, https://sech.me/boinc/Amicable/result.php?resultid=78849434 however there is the occasional 1 that also completed in 15 minutes 22 seconds https://sech.me/boinc/Amicable/result.php?resultid=78860666 I have noticed though if I suspend and resume a task it will go back to the beginning no checkpoints, many complete within 3 minutes. I am not always able to do this to every task. As previously stated throughout this thread I am using a 4080. Apart from using my computer for general things while they are processing nothing else is being used by my GPU
All I'm saying is tasks do not appear to run a consistent time is 3 minutes each on my card

Can you try to run the same WU again, manually? And without anything else running on the PC. I think it was a random fluctuation not related to the WU itself.

Yes I can run it manually if you can give me the steps to do so. (Feel free to message me if you would prefer) I am not sure how I can run the workunit without anything else running? I am comfortable with work units running longer. At the end of the day and need to use my computer while boinc is running. I don't understand why there is large variations in run time when there is plenty of RAM and free CPU cores although it may be a hyper- threaded one and not an actual core. It may be 20/05/24 NZST/New Zealand standard time before I come back to you with result

For that specific WU, just run

Amicable_OpenCL_v_3_09.exe /lpr 127658160073 127658185709 /task_size 200102005550

In a separate folder, then check the output. One of the files will have start/stop timestamps.

How/where do I run it, in command prompt?

Yes, copy the .exe file to a separate folder, and run it from command prompt there.

@Speedy I assume you are using Windows

- right click on windows main button/icon + PowerShell (windows 10) or Terminal (windows 11)
- create a test folder under C:/Local/Test/ (I suggest you use windows file manager if you are not familiar with terminal commands)
- locate boinc data folder and search under /Project the sub-folder for sech.me/boinc/Amicable (if you have no idea where the boinc data folder is, when you start boinc in the boinc log / messages there is an indication of the folder used for your installation, you eventually need to stop / restart boinc to have this message again since it's only displayed once at the beginning of the session log)
- you should find that Amicable_OpenCL_v_3_09.exe in there : copy it into C:/Local/Test/ (again this can be done with windows file manager)
- be sure to be into the test folder by typing "cd C:/Local/Test/" and hit enter (without the " of course)
- type "Amicable_OpenCL_v_3_09.exe /lpr 127658160073 127658185709 /task_size 200102005550" and hit enter (without the " of course)

And then, bonne chance :)
