1) Message boards : Questions and problems : Ubuntu 20.10 but getting error on BOINC (Message 103860)

Hi all

I'm running BOINC on Raspberry 4B with Ubuntu 20.10.
I experienced these issues, and also the issues from this thread https://boinc.berkeley.edu/dev/forum_thread.php?id=14013&sort_style=&start=0.

In addition to many of the suggestions made here, the final solution for me was to follow the Optional Setup Hints for Debian listed here.

Hope this is helpful to someone.

Hi Richard

SETI returned 3 or 4 work units yesterday for you to examine.

Hi Richard

I suspended the tasks manually. I'll run SETI for a number of hours today to give tasks a chance to complete so you can examine the results.

Disabling SLI manually every night is not ideal, since I use the cards in SLI for games. I'll learn to live with GPU 1 clocking up.

On a positive note, I'm loving GPU compute. I've done more work on this machine in 1 month than 3 years on my laptops :)

Thanks for all your help so far!

Regards
Josh

Hi Richard and community. I've some more detailed information to describe my issue.

I've just run SETI work on demand (outside my normally scheduling hours)and noted some key values from MSI Afterburner.

After a restart, both GPUS have the following values.
Core Clock: 51 MHz
Shader Clock: 101 MHz
Memory Clock: 135 MHz

During BOINC Work, the following values are displayed. Remember that only GPU 2 (of two) is performing work, yet the values for both GPUs are identical.
Core Clock: 830 MHz
Shader Clock: 1661 MHz
Memory Clock: 2005 MHz

These values are maintained after stopping SETI from working. So it appears that even after finishing work, the GPUs remain at full clocks. Further more, GPU 1 is clocking up even though BOINC is instructed to ignore it.

Clocks return to normal following a restart. I also noticed that whatever data SETI loads into the GDDR5 is not being dumped after work stops. 367 MBs are occupied both during and post work.

It may be worth mentioning that these GPUs were not purchased 1st hand. I bought both from a single seller to keep me going until I can afford a better solution in a later generation.

As before, this behaviour is only evident after running SETI v7 cuda 42.

Thank you for the assistance thus far.

Hi Richard

I apologise. I should have given more detailed information.

I've been allowing my PC to sleep overnight (thus not working) for the last month until I have this problem resolved. I would prefer to allow my computer to sleep (after 15 mins) during daylight hours, and then use Insomnia (or another app) to keep it awake overnight.

Before I changed the sleep behaviour SETI was running (at least the event log reported completed work and I was awarded credit). Should I allow SETI to run for the next few evenings to give you data to work with?

I have MSI Afterburner on always to preserve custom fan curves and limit FPS for gaming. I'll run SETI and get back to you with some more detailed information.

Regards
Josh

Thanks for your response Richard

Is this what you were after?

23/08/2013 6:37:26 PM | SETI@home | URL http://setiathome.berkeley.edu/; Computer ID 7034435; resource share 200

By scheduling do you mean running for fixed hours over night? The CPU limitation is to keep power usage and heat under control. Using Geforce 320.49 drivers at present.

Happy to post any further required information.

Josh

Hello BOINC Community

I've recently built a new desktop machine, in part for the purpose of running BOINC.

Relevant Info
-------------
OS: Windows 8 x64
Client: 7.0.64
GPU: 2 x ASUS Nvidia 560Ti in SLI
App: SETI@home v7 (cuda42)

I've set my machine to run SETI and other apps overnight. Compute finishes at 7am. When I return to my computer hours after compute finishes, MSI Afterburner reports GPU temps of around 58 (GPU 1) and 40 (GPU 2). These are 15 - 20*C higher than normal idle temps.

Can anyone explain what is going on? There doesn't seem to be a problem with other GPU apps. A restart solves the problem.

Additionally, I've now set <ignore_nvidia_dev>0</ignore_nvidia_dev> since I throttle my CPU to 10% where it can't feed 2 GPUs. Even with this command enabled, GPU 1 still gets hot while GPU 2 is working, even though it's not being used (verified with Afterburner). Perversely, due to airflow constraints, it gets hotter than GPU 2.

Josh

8) Message boards : GPUs : PCIe Bus Saturation (Message 48298)

Hi Ageless

There seems to be some confusion about my question. I mustn't have explained properly.

The motherboard has a Gen1 PCIe x16 slots, so its not a problem of physical dimension.

What I want to know is, if I max out a given graphics card performing work for BOINC (or any application for that matter), how do I know what its interface bandwidth requirements are? I will compare this information against the available bandwidth from the PCI bus to see if I should get a better motherboard or buy a cheaper GPU.

Josh

Thanks for your response Richard

I should have been clearer. My question relates the bandwidth requirement of the card itself.

The Radeon 7770 at my local etailer is a PCIe 3.0 model with x16 connector. I want to know if such a card would saturate a PCIe 1.0 x 16 connector (probably yes). If so, how could I determine bandwidth requirement for GPUs generally?

Hello BOINC Community

I'm considering buying a refurbished desktop to dedicate to BOINC tasks. I'd like to buy a value GPU (eg; AMD 7770) to accelerate tasks. Its likely that said desktop will only have a PCIe 1 bus to equip the GPU.

My question is, how can I tell if any graphics card I buy will saturate such an interface? I understand that PCIe 1 handles 250MB/second/lane. Where can I find out how much bandwidth the graphics card requires?

If a 7770 saturates the available bus, I would prefer buy a cheaper GPU.

11) Message boards : GPUs : Using Sandy Bridge Integrated Graphics (Message 37149)

I understand its not objectively powerful, but I have been impressed by its ability. I thought the Sandy Bridge integrated GPU would be a valuable resource for BOINC. Given it will ship on many notebooks and desktops, replacing other integrated Nvidia and AMD chips. Even operating in tandem with a graphics card it could be a power supplement for BOINC.

It's a shame intel won't releasing an API.

Hi

I've recently purchased a new MacBook Pro 13' which only has the on die Intel Sandy Bridge graphics (Intel 3000 I believe). BOINC does not detect this GPU, according to the messages generated on loading it.

Am I to infer that BOINC is not using my GPU? If not, how can I make it do so?

Thanks
Josh
