I understand that the current options for a BOINC install each have their limitations:

A service install means BOINC will run whether a user is logged in or not, whereas a non-service install (user install?) means the computer will be idle before a user logs in and after they log out, which can be significant proportion of the time. The downside to a service install is that BOINC doesn't have access to VirtualBox or GPU(s).

A non-service install means BOINC will only run when a user is logged in, but does then have access to VirtualBox and GPU(s).

Is it possible to have a hybrid model where BOINC could be installed as a service and non-service, with the service version always running, but allows the user-space version to run VirtualBox and GPU tasks when a user is logged in?

Or run it as a user but have the user automatically load and log in on boot with the system set to not sleep whilst connected to the mains.

Either solution should be possible.

My primary BOINC instance is user-mode with auto log on at power-up.

My command lines for starting and running a second user-mode instance alongside the first, for testing, are:

Start client #2:

D:\BOINC\rh_boinc_test.exe --allow_multiple_clients --allow_remote_gui_rpc --redirectio --detach_console --gui_rpc_port 31418 --dir D:\BOINCdata2

Start Manager #2:

start D:\BOINC\boincmgr.exe /m /n 127.0.0.1 /g 31418 /p password

They should still work if the primary instance is running in service mode.
