I will be converting over my RPi 3B+ to ARM64 Buster. Card already created and just waiting for the cpu application.

Thanks for the update Hy. Interesting times ahead. Optimizations appreciated and the new cpu app announcement is exciting.
Happy to see the devs so active.

Looks like they are still having issues with the Intel igpu application. All of them are having the download issues. No problems with the AMD or Nvidia tasks.

Just an update. The admins/devs have restarted kaktwoos gpu task deployment again in the last hour. Getting both 2.11 and 2.12 species.

Main thing is that they have normal estimated runtimes. The previous issue of incorrectly calculated estimated runtimes is resolved.

Also, the main reason for the new beta application to fix the infinite running of a stopped and restarted task is resolved. Task properties does not show any checkpoints, but I have successfully stopped and restarted Minecraft gpu tasks and they do in fact restart from the same point they were stopped.

The kaktpoint.txt file in the slot is being updated.

Reviewing some of the requirements for running gpu tasks on Nvidia, I was reminded of this statement in the requirements thread.

After installing the Nvidia drivers on Ubuntu, you *must* install the nvidia-opencl-dev packages or the related OpenCL Nvidia headers on your distribution. This has caused major errors due to the OpenCL driver being installed by the package manager, but *not* what helps kaktwoos actually interact with it

I wonder if the people that had the OpenCL enumeration issue ever installed those headers.

I'll provide a couple of task links for my wingmen that errored out their tasks. I've seen two basic wingmen errors, either the application could not download the required 2.12 .cl file or for some reason the application has issues with OpenCL enumerating the gpu in the host.

Most of the errored wingmen tasks were for OpenCL enumeration errors. Predominately older Nvidia drivers but I found other examples with the latest 460.73 drivers like I am using. The Intel igpu hosts look to be predominately the download type errors and I think Neil.rs said he really messed up the copy of that .cl file.

I only ask because I have in the past changed the default checkpoint timer in the Manager for other project tasks that ran for such short intervals it was best to restart from zero instead of checkpoint at 80% of 60 second task.

Devs-Admins, any estimate when you will be sending out new work again?

Looks like a newly deployed beta application has lots of issues.
Most of my wingmen have errored out the tasks.
Either a download issue getting the .cl file or the application can't enumerate the gpu properly.
Also all my finished tasks had wildly incorrect estimated runtimes of multiple days even though the tasks completed in the normal timeframe.
This caused all the minecraftathome tasks to monopolize my gpus and force my other gpu work off the cards.

Can you state whether the application adheres to the standard BOINC checkpointing mechanism whereby the Manager interface can override the default project specified checkpoint interval?

Thanks for the update. I looked over the code and it all seems to be minimal changes. Looking forward to the new application soon.

The developers have implemented a code fix that just needs to be peer reviewed and then merged into the project software.

We should get a new application that properly resumes from a checkpoint in the near future. Crossing fingers.

But I have no exact timeline for you.

Got a confirmation from another user of a problem with the kaktwoos tasks. If for some reason that your PC quits or crashes while running a kaktwoos task, upon restart the task will continue to increase clock time but will never finish.

Pausing or suspending the task and then restarting it does not restore the stalled task to normalcy like this process does with other projects tasks.

The only solution is to abort any previously running task upon restart.

So have the developers been made aware of this issue?
