Was curious if one could do multi-threading with the PRPNet apps somehow like with some of the BOINC Primegrid apps?

You can! But only on 121 and 27 which use LLR (make sure you download the current cllr app for your platform from http://jpenne.free.fr/index2.html), PRS/FPS use PFGW which doesn't support multithreading.

Then, read this and maybe the couple relevant posts below it: http://www.primegrid.com/forum_thread.php?id=7348&nowrap=true#106468

One thing left out of that is that you need to reduce the number of prpclient instances based on the number of threads you're using. So for a quad-core with 4 threads, just one instance would be needed, or two tasks of two threads, use two instances.

Ok here is what I did:

1. I downloaded the updated console llr windows app from here - http://jpenne.free.fr/index2.html as you suggested. The app that I downloaded b4 was ancient apparently. So was a needed updated.

2. Created a batch file in my prpclient-1 directory for the 1 instance I will be running. the batch file is called cllr.bat and only has one line: "@cllr64.exe -t2 %*" no quotes.

3. Edited the prpclient.ini file with the line for the llr.exe app. It now reads - "llrexe.exe=cllr64.bat" (again no quotes).


So now when I run the prpclient.exe (or the single start batch file), it uses that cllr64 batch file to start the cllr main app with the number of threads I'd like to use. -t2 for 2, -t4 for 4, -t8 for 8, etc. just change the batch file for the number of threads.


Very nice. Will leave this running once my SOB task finishes and see how it does.


Thanks for the help with those links.

Update #1:

After running several tests for a while using -t there is no difference in cpu utilization. Running cllr64 with the -h parameter shows there is no -t parameter available when it lists them. Hmm



ideas?

Make sure you're using the latest version of LLR. It should be v3.8.21.

EDIT 1: Use "cllr64 -V" to see the version number.

EDIT 2: The -h help doesn't show -t. :)

I edited the batch file to try a "-t2" and a "-t 2" without spaces and with spaces and the same thing. Tried -t8 and -t 8. Still only works on 1 core.

This is puzzling.


no error messages either.


I also tried adding -d to the command line in the batch file and it doesn't output any other info to the screen.

If you're running *OUR* BOINC tasks, you need to use a space in the app_config file. That's what is required by our wrapper.

However, if you're giving the parameter directly to the LLR program, as you are with your batch file for PRPNet, you must *NOT* use a space.

So, for BOINC, you use "-t 4".

For PRPNet, you use "-t4".

(Leave out the double quotes, of course.)

Ok here is what I did:

1. I downloaded the updated console llr windows app from here - http://jpenne.free.fr/index2.html as you suggested. The app that I downloaded b4 was ancient apparently. So was a needed updated.

2. Created a batch file in my prpclient-1 directory for the 1 instance I will be running. the batch file is called cllr.bat and only has one line: "@cllr64.exe -t2 %*" no quotes.

3. Edited the prpclient.ini file with the line for the llr.exe app. It now reads - "llrexe.exe=cllr64.bat" (again no quotes).


So now when I run the prpclient.exe (or the single start batch file), it uses that cllr64 batch file to start the cllr main app with the number of threads I'd like to use. -t2 for 2, -t4 for 4, -t8 for 8, etc. just change the batch file for the number of threads.

Hi The bold text should be the same

Ah yes, they are the same, that's a typo. Both read cllr64.bat. Good eyes!
