bunch of WU processed :)

and plenty others


Thx! Good to see it's working, and that run times are reasonable on Intel's newest GPUs.


Run times are longer for the Intel GPU tasks. Are they doing larger amounts of science and should the credit amount be higher ?

Run times are longer compared to what? Compared to the previous dataset, run times are longer and credits have gone up accordingly.

If comparing to a different gpu then average times will probably be different. Each WU is a fixed amount of work and therefore has a fixed credit. Just because they run longer doesn't mean they deserve more credit. If it's running longer than expected then it could be an inefficient driver or bad OpenCL implementation.


I was comparing to a default Windows Get Decic Fields v4.00 (default)windows_x86_64

You may have a point about Driver or implementation

I have added two systems to the project in the last 24 hours that have Intel GPU's. After reviewing this tread and seeing that some Intel GPU's have been identified as successful and some not. Can the successful models be added one or more at a time, to the look up table, for optimization ?

From my first successful task

GPU Summary String = [INTEL|Intel(R)UHDGraphics620|1|3227MB||300].
Loading GPU lookup table from file.
GPU was not found in the lookup table. Using default values:
numBlocks = 1024.
threadsPerBlock = 32.
polyBufferSize = 32768.


System information
GenuineIntel
Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz [Family 6 Model 142 Stepping 11]
(8 processors) INTEL Intel(R) UHD Graphics 620 (3227MB) OpenCL: 3.0

Thank you

You have more months of experience to consider now. Are you leaving the App as BETA because of the issues that the weaker IGPU systems may have with inexperienced users or other reason's ?

Thanks

So another year has come and gone.

This was not the best year. We started the year with a severe hard drive crash that took weeks to recover from. After that, the year was spent on the search over ℚ(√2) (subfield 3). This search should be complete within several months. A single search seems like a small accomplishment, but I should point out that this is a gigantic search that just several years ago seemed out of reach.

Other than that, in November support was added for Intel GPUs. The app worked for the most part but performance was disappointing. We look forward to the new Intel Arc GPUs coming out this year which should perform much better.

Thanks everyone for your contributions and have a wonderful New Year!



If the Intel GPU application is stable you may get more usage if you take it out of BETA status. Some people do not want to run Test applications and do not have that option checked in their Project preferences.

Thanks

It didn't find my nvidia gpu
GPU Summary String = [CUDA|NVIDIAGeForceGTX1650|1|4095MB|49676|300].
Loading GPU lookup table from file.
GPU was not found in the lookup table. Using default values:
numBlocks = 1024.
threadsPerBlock = 32.
polyBufferSize = 32768.


That's because it's not in the lookup table. But no worries, performance should still be relatively good with the default values.



A NVIDIAGeForceGTX1650|1|4095MB|49676|300] is a pretty mid range GPU that I believe has been around for a while. Are the project developers having to build an entire look up table or are there common industry tables available ?

I did not see that anyone advertised the updated BOINC Clients on this projects Forum Boards.... back in Sept of 2020.

Version 7.16.11 of the BOINC client software has been released for Mac OS and Windows.
