Re: Work unit availability

I still have PVs from day 1. How could someone have that many or be that slow?

such is the life of BOINC cross-validation. some people like to download tasks and shut off their computer for a month. in these cases you just need to wait for the deadline to pass and get the task sent to another host, taking the risk that the next host doesnt do the same thing. It's not uncommon for a WU to be replicated 4, 5, 6 + times before it finally lands on two hosts willing to actually process it.

Re: Work unit availability

I am observing strange behavior in relation to (or so I think) OPNG tasks across different computers.

I have several machines that are set to use GPU and several where GPU usage is disabled (GPU does not exist from BOINC app standpoint). On those PCs where GPU usage is disabled, I keep getting CPU tasks (OPN1, MIP1, etc) on a regular basis, i.e. business as usual. However, those machines where GPU usage is enabled are not getting any CPU tasks for days and I see the following messages in the Event Log:
No tasks are available for OpenPandemics - COVID 19
No tasks are available for OpenPandemics - COVID-19 - GPU
No tasks are available for Microbiome Immunity Project

Apparently, these statements are not correct since my other computers are getting OPN and MIP tasks without issues. I wonder if OPN GPU task availability somehow affects ability to get CPU tasks for machines in question? I really have no logical explanation for this strange phenomenon.

Can someone with inside knowledge of WCG functionality please shed some light on this? Thank you.

Re: Work unit availability

They would still get that message when they have filled their queue of tasks if they are getting CPU tasks. If I understand your post correctly though, the machines that have GPU usage enabled are not getting any CPU tasks. If they are not getting CPU tasks at all:

FWIW, there have been a few times that I thought the schedule requester was not doing what it should. Each time I enabled sched_op_debug to gain insight into the matter. The result was that it pointed me towards some setting that was not set to what I thought it was set to.

One of the ways to enable sched_op_debug:
Boinc Manager -> Options -> Event Log options -> check "sched_op_debug"

Re: Work unit availability

If you have machines set to receive GPU tasks only and "Allow research to run on my CPU" set to no in the profile for those machines then you will not receive CPU tasks from any projects on those machines.

Re: Work unit availability

A combination of low wu production, more folks interested now that it's not beta, and the script kiddies trying to suck up all that they can get. No way to stop the script kiddies as far as I know.
The kitties are not getting any here either.

I set the project to look for new WUs at an interval of approximately 5 mins.
So far I have had a few WUs every day. GPU Usage on the Nvidia under WinX is around 16%, while the slower Intel GPU under Linux is working 24% of the time.

Re: Work unit availability

Hello, I apparently keep receiving GPU tasks on my linux platform that are not being executed somehow. Boinc correctly finds my gpu (both with mesa clover and with amd opencl):

OpenCL: AMD/ATI GPU 0 (ignored by config): Radeon RX 560 Series (POLARIS11, DRM 3.40.0, 5.10.0-5-amd64, LLV (driver version 20.3.4, device version OpenCL 1.1 Mesa 20.3.4, 4096MB, 4096MB available, 1567 GFLOPS peak)
OpenCL: AMD/ATI GPU 1: Radeon RX 560 Series (driver version 3188.4, device version OpenCL 1.2 AMD-APP (3188.4), 4065MB, 4065MB available, 2507 GFLOPS peak)

But then reports:

[work_fetch] --- state for AMD/ATI GPU ---
[work_fetch] shortfall 17280.00 nidle 1.00 saturated 0.00 busy 0.00
[work_fetch] share 1.000
choose_project: scanning

AMD/ATI GPU needs work - buffer low
[work_fetch] set_request() for AMD/ATI GPU: ninst 1 nused_total 0.00 nidle_now 1.00 fetch share 1.00 req_inst 1.00 req_secs 17280.00
AMD/ATI GPU set_request: 17280.000000
Requesting new tasks for CPU and AMD/ATI GPU
[sched_op] CPU work request: 683.75 seconds; 0.00 devices
[sched_op] AMD/ATI GPU work request: 17280.00 seconds; 1.00 devices
Scheduler request completed: got 1 new tasks
[sched_op] estimated total CPU task duration: 36631 seconds
[sched_op] estimated total AMD/ATI GPU task duration: 0 seconds

and project is backed off by scheduler. I have switched on all the gpu toggling options and enabled computation while computer is in use, but gpu never works. Am i doing something wrong? Should i stop altogether asking tasks? Thanks in advance

The minimum requirements for the project is OpenCL 1.2. Your Mesa driver only supports 1.1. https://www.x.org/wiki/RadeonFeature/ states that OpenCL is supported via ROCm for recent AMD GPUS. I am not sure how well ROCm is supported by BOINC.
Maybe some one else here has found a guide on how to get the AMD GPUs working.
I have an old Radeon HD 6950 I'd like to get into service for WCG, but was also unable to get it working under Ubuntu 18.04.

I know, this is why in also installed amd's opencl driver that has 1.2. If anyone experiences the same problem let me know, we might start a new thread to get amd gpus working.
