Dear community,

I've installed a PC in my basemenet dedicated to run BOINC projects.

Whenever I access this PC from another PC per Microsoft Remote Desktop RDP, calculations performed on its GPU will stop. To continue GPU calculations, I have to physically go to the PC and log in again.

I guess that the RDP connection sort of "pulls away" the GPU from the session, so it might primarily be a Microsoft topic. However, maybe one of you did encounter the same issue and knows a solution.

Both PCs run Windows 10 Pro 20_04, the GPU in question is an NVIDIA GeForce RTX 2060 with an actual driver. There's no virtualization in place. BOINC manager is 7.16.7.

Thanks and regards
Oliver

This is a known problem, and is caused by security measures introduced by Microsoft into the GPU driver model from Windows Vista onwards. There is no known way of combining Windows RDP with GPU crunching.

The workrounds available would depend on what exactly you wish to do.

If you wish simply to observe and manage BOINC remotely, follow the steps in Controlling BOINC remotely. You can either use a standard copy of BOINC Manager to access the remote machine, or you can use a third-party utility like BoincTasks. BOINC Manager can only display a single remote machine at a time: BoincTasks can combine the data from multiple remote machines.

If you want to go further and retain remote access to the entire Windows environment on the remote machine, you would need to switch to a different remote access solution, like one of the many flavours of VNC.

Dear Richard,

I installed "BOINC Tasks" and it completely solves my problem.

Thanks a lot for pointing me to this solution!

Best regards
