Click on “Ubuntu software” and search for BOINC, click on install next to BOINC Manager.
To add graphic drivers (CUDA/OpenCl) go to ‘System Setting‘ and select ‘Software and updates‘, next click on the tab ‘Additional driver‘, wait and install any missing driver.
Allow remote access to the BOINC client:
Click on “Show your applications” , in the search field type ‘terminal‘ and select the terminal icon, you need to do this to get the right permission to edit the files.
In the terminal type ‘sudo nautilus‘, in the next screen click on ‘+ Other locations’.
Now select ‘computer‘ and enter the folder ‘var‘ ,’lib‘ and ‘boinc-client‘ \var\lib\boinc-client.
Right click on the file ‘remote_host.cfg‘, open with text editor and at the end of the file enter the IPv4 address (or addresses each on a new line, without any spaces or comma) of your BoincTasks computer. It is best to setup a fixed IP address on the computer running BoincTasks.
Now open ‘gui_rpc_auth.cfg‘ and enter a password. So this is a file that only contains the password, or is empty when you don’t use a password.
In the upper right hand corner, click on the two arrow (network) icon, next click on ‘Connection information‘, write down the IPv4 address and the MAC (Hardware Address).
Restart the BOINC client:
For the changes to take effect, restart the computer or the BOINC client.
Go to the ‘Terminal’ and type ‘/etc/init.d/boinc-client restart’
The BOINC client is restarting and the changes will take effect.
Connect to BoincTasks:
In BoincTasks, select ‘Computer->Find computers‘, the address is the start of the address range of the IPv4 of the remote computer.
Click Scan address range, the remote computer should show up, if it doesn’t check, your firewall.
Select the checkbox left of the IP and MAC of the remote computer and click on ‘Add selected’.
If the IP address of the remote computer isn’t fixed or you don’t know, click on the IP Address and make it blank, so it leaves the MAC Address. The MAC Address will be used to find the IP Address of the remote computer.
You know the IP address and the remote computer IP address is static, leave the IP Address in the field, this connects slightly faster than with the MAC Address.
If needed fill in the Password or make sure to leave it blank.
Connect to BoincTasks Js:
In BoincTasks Js , select ‘Computer->Find‘.
Enter the password and port, if you have different passwords or ports, repeat until you find all computers.
Next press Start.
If your see Unable to connect, the computer is found but the password might be wrong or the computer running BoincTasks Js isn’t allowed to connect.
Checking GPU usage:
Click on “Ubuntu software” and search for ‘psensor‘ if the usage is less then 100% you may consider running multiple BOINC clients.
Make sure the GPU drivers are installed: ‘sudo ubuntu-drivers autoinstall’
The OpenCL interface might not be installed, do so with ‘sudo apt install ocl-icd-libopencl1’
