I am not clear on how to get tasks from the "test" queue. According to the apps page, it requires "Linux running on an AMD x86_64 or Intel EM64T CPU". But if I understand correctly from the above posts, the app is for a GPU, not CPU. FWIW, I do have an AMD VII and the settings are configured to allow both GPU and CPU for the "test" application. Also the server status page says there are 40 tasks available with 8 in progress. Yet I am unable to get any, either for CPU or GPU. What am I doing wrong?

Cuda on linux has never worked for me to date. But with 9.8, it is working now. Nice!

Yeah, after more experimentation, using *any* of my i5-4590 (4 core, no HT) cores for other BOINC CPU tasks causes the GPU utilization to zero out. In other words, if I run only a single GPU task, GPU utilization is ~40% and CPU utilization is ~50%. If I allow even one other CPU tasks from another project to run, you would think the only thing that would change is that the CPU utilization would increase to ~75%. But that's not what happens. CPU goes up to ~75%, and GPU drops to single digits. Perhaps the chipset bus bandwidth is just maxed out with a single GPU task? This is a very old chipset, after all. I would like to compare this to a more modern chipset, but I can't, because all my new machines just error out (see other threads).

The three machines that have nothing but errors are

- Threadripper 3970X, 2x RTX 1660 Ti (Dual boot Win10 and Linux, tasks fail for both)
- Threadripper 3970X, 1x RTX 2080 Ti + 1x GTX 1080 Ti (Dual boot Win10 and Linux ,tasks fail for both)
- i9-9820X, 2x RTX 1660 Ti (Win10)

Latest Nvidia drivers for all three.

Not sure what the vbox questions are about? This project doesn't use vbox. These are native tasks.

The thing that makes me wonder what's going on is that not even the CPU tasks work. They used to work just fine. Putting aside the GPU problems, something else has changed and is causing problems.

Also, my three other dual GPU, win10 machines continue to fail 100% both CPU and GPU tasks.


To be clear, those three machines have about a million credits combined. So at least CPU tasks used to work. But no longer.

My RTX 1660 Ti runs a single task with a load of around 40%. This is on an old i5-4590 (4 core, no HT). I will also note that it also consumes two full cores. So I set my app_config.xml file to reserve and 2 CPU per GPU task. If I let BOINC use more than two cores for other tasks, the GPU utilization drops way down.

<app_config>
<app>
<name>mldstest</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>2</cpu_usage>
</gpu_versions>
</app>
<app>
<name>mlds-gpu</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>2</cpu_usage>
</gpu_versions>
</app>
</app_config>


Also, my three other dual GPU, win10 machines continue to fail 100% both CPU and GPU tasks.

FWIW, I have only 1 of 4 machines that are working with GPU tasks.

working:
Win10 with a single 1660 Ti

errors:
Win10 with dual 1660 TI
Linux with dual 1660 Ti
(same machine dual boot)

Win10 with one 2080 Ti and one 1080 Ti
Linux with one 2080 Ti and one 1080 Ti
(same machine dual boot)

Win10 with dual 1660 Ti (this is the one I sent the output file for)

All are running the latest drivers available.

Sure! Just send me the directions and where to get the files.

This task worked on a windows machine. It's a single GPU machine. I wonder if that is why my dual GPU windows machine gives errors.

Any idea why this one machine is throwing nothing but errors, with test units, both CPU and GPU?

Edit: To be clear, no errors on any other projects at all.

Also, if you send out tasks that allow any resource to use them, then they get consumed by CPUs. And you won't get testing just on GPUs, assuming that is your goal for this batch.

I haven't received a task for my windows machines yet.

But if the ram/storage requirements are significantly different, then yes, perhaps a different app is required, so that people can select one and/or the other.

It looks like you fixed the issue. Great!

Out of curiosity, what was the problem?

FWIW, I have 5x Raspberry Pi 4 machines crunching quite happily. Right now they are working on WCG, but will come back around here sooner or later. They are OC to 2ghz and have coolers. But then again, x86/x64 machines have coolers too. OTOH, they use less energy combined than a dim light bulb.

Just to let you know there is progress. This is with a rand_automata/DS3 datafile. Want to get it into testing tonight or tomorrow.


Awesome! My GPUs are eager to test.

If you are running 64 bit, be sure to add these to your cc_config.xml to be able to also receive 32 bit apps/tasks:

<alt_platform>arm-unknown-linux-gnueabihf</alt_platform>

For the record I changed the shmem size buffer to a (much) larger size. Orders of magnitude larger. Lets see if that improves the situation.

Hmm. It doesn't seem to be working.

Are they pre-assigned to a particular CPU/OS, and there aren't candidates of those flavors asking for tasks? Just guessing.

I see that there are two apps, regular and test. And the server status page shows that the test tasks have 3 in progress, with 17 unsent. Why unsent? I have 2 of the 3 tasks in progress running on my Raspberry Pi machines. So I know some are being sent. I also have windows and amd64 linux machines attached and asking for those tasks unsuccessfully. What is holding up the rest of the test tasks from being issued?
