I am not sure where to ask this. So, I will do it here. I tried to clone BOINC, to run multiple copies. I let windows make the copy. When I tried to start the first BOINC it wouldn't connect, same with the second. So, I had to re-download and run a repair. Before I attempt to try this again. I was wondering if anyone knows what the best way would be?

First question is why would you need it?

To run multiple tasks. From the drop down list on the manager, it appears that BOINC is only running one task at a time. I don't use my machine much anymore, figured I would make it do something useful!

BOINC will run as many tasks as there are CPU cores and under normal circumstances, 1 task per GPU. So if you have a 4 core with hyper threading with a GPU, it's 9 tasks.

If it doesn't do that, you either don't have enough work in cache to supply all CPU cores, or you set preferences to use less 100% of the processors.

By default BOINC will only start one time. It will check at startup whether another BOINC is running, and if there is, it won't start the second one.

"Cannot connect to client" problems stem from BOINC Manager being blocked, normally in the firewall, so it cannot contact the client. BOINC is a two part program, the client BOINC (boinc.exe), and the graphical user interface BOINC Manager (boincmgr.exe). These two parts talk to each other through RPC, so real-time updates can happen in BOINC Manager.

Therefore, you'll need to allow boinc.exe and boincmgr.exe on TCP port 31416. Separately, boinc.exe needs to be able to talk to project servers on the internet on TCP ports 80 and 443.
