Hi all. After a looooong hiatus I'm getting back into PG, and noticed multithreading is now a thing. My 2018 MacBook Pro has eight cores, and I wanted to see them shred through SoB tasks. After plenty of experimentation, I haven't gotten anything to work. The result is always one task = one core.

Here is my config file, located at ~/Library/Application Support/BOINC Data/projects/www.primegrid.com/app_config.xml:

Here's what my app_config.xml file says and it was working on a mac. I don't have access to the mac at the moment to tell you what folder I was using.

<app>
<name>llrSOB</name>
<max_concurrent>1</max_concurrent>
<fraction_done_exact/>
</app>

<app_version>
<app_name>llrSOB</app_name>
<cmdline>-t 4</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>

You did say you did a Read Config files from boinc right? You shouldn't even need to restart boinc. Also, I have my use cpus set to 50% but set to use them 100% of the time.

Did you look at the event log to confirm it read in the app_config settings. And you are not using the cc_config file right?

BOINC is configured to read off web preferences from PG. It is configured to use at most 8 microprocessors.

With that in place, I explicitly request to read from config files, then quit and restart the app. I kill my existing CPU tasks and fetch new work, making sure to have only two WUs ready in the end. When BOINC starts crunching numbers, I look at OS X's Activity Monitor. I see only two processes called primegrid_llr running, each using 100% CPU and one thread.

Any thoughts about what I'm missing?

100% CPU is usually all 4 cores maxed out. In BOINC under tasks does it show it using X number of CPUs under the tasks status? It should say in parentheses (4 CPUs)

A couple of my pc's don't show the actual number until they get new tasks, if I change the app_config file after suspending the wu's and then saving the file and restarting the tasks it doesn't show the number in parenthesis. BUT it does run using the app_config settings.

I have never seen any CPU task have a status of anything more than 'Running'.

To bring up a point Rick made, I'm not entirely clear the log has ever explicitly mentioned reading an app_config file. At best, all I can remember are log items saying BOINC was making an effort to look for 'em.

Looking at the log now after running a 'load config file' operation, I see something odd:

Thu Jan 31 17:33:45 2019 | | Re-reading cc_config.xml

I don't have a cc_config.xml file. And why doesn't it mention the same for app_config.xml?

I still think with 100% cpu usage on 1 running task it's using all 4 cores...

I think might have confused one of the files. The one I was thinking was app_info.xml which is a much more stringent configuration file. So if it's looking at that there might be an issue.

I looked at my mac and it has app_config.xml file in the same folder you mentioned.

Are you actually getting 4 tasks and they are running at the same time? Or did you get 1 task but the cpu is running 100% because that's 2 different things and Penguin is correct on his statement. The task does tell you how many "cores" it's using in the name/description of the task.

I just clicked to read mine and it said "re-reading cc_config file" also and then after it went thru it it says "found app_config.file"

Here's what I found after reading in my config files from options

Re-reading cc_config.xml
cc_config.xml not found - using defaults
Found app_config.xml

The task itself is saying Running (2 CPUs)

I also have use at most 50% of my cpus and use my cpus 100% of the time. And under activity I have everything check to Run always.

I'm thinking it's not finding your app_config.xml file for some reason.

Not being a mac person I did have an issue a long time ago with the permissions on the app_config.xml file. When starting boinc it would tell me that file was not accessible or something and I had to change permissions on the file (well I had to get someone to help me with that)

Did you restart Boinc? And one last thing you might try, remove and reinstall with the latest version (you may already have that). I'm pretty much out of ideas now since everything you've told us seems to make sense and should be working.

A reasonable idea! In Terminal I ran chmod -R 700 ~/Library/Application Support/BOINC\ Data (i.e., fairly liberal permissions on the BOINC directory and any subitems), then attempted to read local config files again within BOINC. No change. :(

Then why not delete the file and just start over? In Windows if you don't use a text editor the file won't work at all, Word etc type programs add things that Boinc itself doesn't understand and the file won't run. The other thing the Windows text editor does is try to append a ".txt" onto the end of the app_config.xml file, check yours to be sure it ONLY says app_config.xml and nothing else and that it's in the Boinc/projects/primegrid folder too.

Ah, sorry: this is vim.

I just quit BOINC and nuked my config file. I started from scratch, typing everything manually, using Rick's file as a template. I reopened BOINC and ran the read config files command. Still no mention of app_config in the logs.

I use notepad++ for this stuff, (very good tool) or just plain old notepad. Works fine.

I finally got this working. Even though there was a BOINC Data directory at ~/Library/Application Support, the true working directory is /Library/Application Support. After moving my app_config there and restarting, my SoB tasks read 'Running (X CPUs)'.

The feeling of crushing one task in 48 hours is magical.

Hey just a question on this app_config file. Do you guys also use it for all other applications?
iw - SOB,WOO,CUL etc

I'm currently using it for the TdP comp but wasn't sure about it's use on other projects.

thx

So would it look something like this -

I've never been very good at these app_config files :/
And basically you could just keep adding to that list (ie >llrESP< etc etc? and have one large app_config which would work with all those llr projects?

I feel ……… annoying for asking but I really struggle with this computer jargon. Building a pc is easy.... understanding this kind of stuff isn't (well for me anyway.)

Oh thank you Keith!

So the space between the 2x </app_version> (separating the 2 projects) will still work?
I always though there couldn't be a space :)

That's great. Thank you for your patience in teaching me the ways of pc code :)(or whatever is the correct terminology)

Ohhhhh I see!! Sorry, I thought I needed those at the start & end of each subproject to open & close each one off.

Gee...told you I was terrible at understanding code. Bet I can't even use my age as an excuse! (40 yrs old) :D

I'll give that a try. I'll just need some time because I've got to change the config file across all
5 PC's :( Oh...and go to work of course.

Thank you very much Mikey!

And why at 66 years old I'm where I am having quit for over 40 years and only using it for Boinc now. A friend forced me to use a text editor to help with his website about 15 years ago, I got it hung up one day for over 2 hours as I looked for a punctuation point in the wrong place!! I switched to a program that would let me see the problems much easier and eventually so did he. But todays coding is MUCH harder than all of that stuff and even harder than using those paper tape rolls waaaay back in the late 60's.
