Development for LHC@home

Hi

I have 2 theory simulation VB tasks running on my Intel i9 late 2020 iMac (latest version of macOS 15.3.1 and latest version of VB 7.1.6).

All the CPU capacity of the machine is not used at the moment, I can there are some spare cycles (average 10% unused in the past 6 hours, I can measure this with iStats Menus). They have been running for a good number of hours as you can see.



I realize that one is using a fair amount of CPU (here 70% of a thread in the screenshot), and the second one almost none.



You can clearly see the total amount of CPU time is 30mn (after 6 hours running), compared to 8 hours for the other one (after 9 hours running).

How can that be ?

Thanks for reporting.

The process showing around 30 min CPU within 6hrs runtime most likely hangs.
The scripts running inside the VM are currently under heavy development.
This affects BOINC level as well as deeper levels (scientific app).

Fortunately vboxwrapper 26210 seems to fix an issue on MacOS that has been introduced with the version before.

I think the shutdown file was not being created at the end of the job. This has hopefully been fixed in v7.47

Thanks a lot for your quick answers, I know I'm on a dev/test project and I'm here to help :)

Glad to see a future version might help.

Is there anymore information I can provide you ?

(but I won't be home before this evening and I don't have remote access on my iMac)

To continue on this topic you can see here a group of theory simulation, some 7.46 and two 7.47


and one of the 7.47 is having the same symptom of "no CPU used" that I had mentioned.
