I'm keen to do some work units for this project on my Mac. Are there likely to be any available in the near future please?

Yes, we are planning an app for Mac!

You can also participate in the original project with Mac (https://covid.si/en/), the installation instructions are here. But we want to issue a BOINC application as well and you are very welcome in the BOINC project.

Can I help or assist you in porting the application and wrapper to macOS?

It would be good :) Please contact me via nikitina (at) krc.karelia.ru or give me your e-mail and I will write you.

Great to see that you plan for future support of MacOS. And thanks Dosch for volunteering to help with porting the app!

Many thanks to Dotsch for porting the app to MacOS! Now it is in project's app versions and should work. :)

Tested the new application and get an exec error:

Don't know why... Searching for the problem...

I think it's my fault, I did not put execution permission on worker script. Sorry! Now this is repaired.

That's awesome. Thank you so much Dotsch for volunteering and porting this application this quickly. Great job! Just downloaded my first WUs on a MacOS system.

bozz4science, does it work on your Mac?

Still got some strange errors. The script errors out. I guess the script is broken. Natalia, can you please, verify the sha256 checksums of the rbdock script one the donwload :

Can you resend me the working script please?

Send you a mail...

No. Unfortunately all 8 WU errored out almost immediately (5-30 sec runtime each). All "stderr" files state an error 195 (0x000000C3) EXIT_CHILD_FAILED.

Pls see for reference the following WU f.ex. https://fightcovid.boinc.ru/sidocktest/result.php?resultid=174785

I paste the stderr file here for convenience.

<core_client_version>7.16.11</core_client_version>

I created a new app version, let's hope it works :)

I’ll give it another shot and report back to you whether it works or not. Thanks for the quick bug fix!

Edit: I am now ~15 min into the new MacOS supported WUs with version 11.06 and they seem to be crunching away just fine. Will get back to you once I know if they finish and validate successfully. Seems you all did a good job of porting this application.

Thank you booz4science!

My Mac is also crunching with the new application.

Just wanted to update you shortly. First MacOS WU (11.06 app version) recently finished and validated. Runtime seems to be in line what can be expected from the results returned so far from my other machines. No hiccups whatsoever. Seems to be working just fine

Looking forward to contribute with my Mac as well. Thanks again for helping the development of the MacOS version of the app Dotsch!

Just wanted to check back to you shortly as I the majority of my tasks reporting ~70 MB (±5 MB) physical memory but ~4.15 GB (±150 MB) virtual memory. It seems to me that my Mac system is currently overwhelmed by the RAM requirements of the tasks. Should I scale them back to address this, i.e. running 2 instead of 4 tasks simultaneously? I am crunching on a system with 8 GB RAM.

bozz4science, hi!

Under Linux we see ~78 .. 80 Mb RAM - both for Virtual and Reserved.
What gives out command
top -b -n 1 -p
?

Thank you!
