It is interesting, when are you going to resume Search 3?

Probably not until early next year. We are getting more bang for the buck with sf7 at this point.

The fields are rare, on average approximately 1 per 1000 WUs.

Is the count that the badges are based on shown on the User page ??

I have the following counts on my page is one of them the one ??

Decic count 87
Septic count 11,258
ℚ(√-10) count 1


Yes, its the ℚ(√-10) count, otherwise known as "subfield 7".

Cool! How many fields do you need for every color? 10 - 50 - 100?


That is correct, 10-50-100.

The badges have now been implemented. The badge is a portrait of Galois, considered by many as the founder of field theory.

There are currently 3 levels of badges: bronze star, silver star, and gold star. Some more levels may be added at a later date.

So, how do i know what my status is on sf7? (or any subfield) Will you also break out those stats on our account page?


The counts are implemented, I just need to add the software hooks to display them on the various web pages. Until I do so, you wont know your status.


The new field counts are now on the stats page and the account page (I believe that's all the pages that need it). I still need to implement the badges.

If nothing else works, I can manually add the other team member as an admin for you. Just let me know.


Yes, I did everything correctly and I started again several times.
If you can do it manually, I would appreciate it :)


Ok, I added your teammate as an admin.

To help increase interest in the project, I am creating a new badge based on fields counts, and tuned especially towards subfield 7. If this works well, I will also create separate badges for the other subfields.

I already put the hooks in to keep tract of the field counts for sf7. Now it's just a matter of creating the badge images, etc. Hopefully that should be done in the next several days.

Happy crunching!

I am the founder of the team, yes.
But I want to appoint one of my teammates as admin.
This functionality is possible by entering the email address of the person intended to be admin in the administration section of the founder.
But every time I try it fails.


I played around with a test team and I could only get your error when the user's email was not already in the system, and in addition to the "could not handle request" error, it also said "no such user".

I see your team only has 2 members. Are you sure you are entering the person's email correctly?

If nothing else works, I can manually add the other team member as an admin for you. Just let me know.

By administrator do you mean founder?

It looks like there are 2 members of your team and you are the founder. Everything looks normal from this end. Can you give me more specific details of your problem?

Mr Eric,

Is there a noobs guide for what you're talking about in this thread.

For years I've been just running a spare computer with whatever happens when you run BOINC by default. CPU only, no GPUs. Wondering if there's anything I can do to get more performance out of it.


This link explains the app_config.xml file
https://boinc.berkeley.edu/wiki/Client_configuration

The app_config goes in the project directory. It gives extra control of the client. If not present, the default configuration is used, which in general is good enough for most users. I personally didn't need to use it until I had a much better GPU and wanted to run more than one task at a time.

Post:
When you are running 2 tasks at a time how much CPU do you give to each task? Example 0.5


I think you are asking how to set the "cpu_usage" tag in the app_config.xml file.

This will vary depending on your cpu. I have mine set to .20. I got that by looking at what the cpu usage was for the gpu task when it was running a single task.

In case it helps, here are the contents of my app_config.xml file:
<app_config>
  <app>
    <name>GetDecics</name>
    <fraction_done_exact/>
    <gpu_versions>
      <gpu_usage>0.49</gpu_usage>
      <cpu_usage>0.20</cpu_usage>
    </gpu_versions>
  </app>
</app_config>

On WIN 10 I have a gpuLookupTable_v402.txt.
My GTX1080 Ti is not listed and is running with little load / in standard mode (stderr.txt).
Is there a table/values ​​that better utilize the GPU?


The default values should work well enough. The lookup table is for fine tuning and usually gives less than a 10% improvement.

If GPU utilization is less than 100%, you can try using the app_config.xml file to have it run more than 1 GPU task at a time. I have done that myself to raise my usage from 90% to 100%. Individual run times go up but you process 2 WUs at a time.

Can someone create a script that would run test workunit and tune worker?


This has actually been done. It took some searching but I found where this was discussed in the past:
https://numberfields.asu.edu/NumberFields/forum_thread.php?id=488&postid=3063#3063

In a nutshell, there is a public github project with all the source code and testing scripts. For the GPU testing, see the README file in the test directory. And don't hesitate to ask if you have any questions.

Also see this for a discussion of the lookup table:

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
Bill F


Yes, a line could be added to the lookup table. But there is no reason to do that until someone has done the dirty work of determining what the optimal settings should be. The default settings were chosen conservatively so they would work well for most cards.

If you were interested in trying to get optimal values, one thing you could do is edit the gpuLookupTable.txt file in the project directory to add a line for your gpu. You would have to run enough WUs to get a good average in order to compare your new settings with the default settings. And it would definitely help to understand the underlying architecture of the gpu to give a good starting point for the settings. For example, Nvidia uses a "warp size" of 32, which is the number of threads to keep in lockstep, and it turns out the optimal value for threadsPerBlock was 32.

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
Bill F


Yes, that is the primary reason. And it's easy to enable beta apps for those that want to try it out.

Yes, we only use integer ops here.

The good news is the results are correct.


Since OpenCL makes arithmetic errors on AMD and Intel GPUs (for 64-bit integers at least), how do you know if the results are correct? I am curious since this project has single-task validation.


What do you mean by "OpenCL makes arithmetic errors... for 64-bit integers".

That should never happen. I could possibly see 64-bit floats having some round off errors, but not integers.

Anyways, during development, I ran hundreds of GPU cases and compared against the CPU versions and they all agreed after computing billions of polynomial discriminants. So I am pretty confident when I say the OpenCL code produces correct results.

Thanks to all participants!

I had to disable the "accelerated retries" mechanism due to all the abortions. When things stabilize I will turn that back on. This means reissued WUs will have their deadline halved.

Hopefully they all uploaded by now. I had the same problem last night but when I woke up this morning everything was fine.
