Is this computer connected to the right venue? Does it have VirtualBox installed? ID: 36156 · Reply Quote

Hi all, I have one specific host that will not download any CPU tasks. This host has only run sixtrack so far and at the moment, sixtrack doesn't have work. Other sub-projects need VirtualBox, did you install it already ? Did you allow the client, to get work from sub-projects other than sixtrack ? Note that the function "If no work for selected applications is available, accept work from other applications?" doesn't work here Supporting BOINC, a great concept ! ID: 36175 · Reply Quote

I haven't modified any options other than Resource Share. That usually happens when the server has no tasks AND if you ask for the VB tasks but do not have VB installed. Yours does say it has 5.2.8 but that is getting old as far as all the updates Oracle does. So maybe just do the d/l/install/and reboot and then try again. (VB 5.2.16) https://www.virtualbox.org/wiki/Downloads (I know some members say you don't need the Extension Pack but I always install that too and it takes about one minute to do that) ID: 36189 · Reply Quote

I am using 5.2.16 on my Linux box and 5.2.12 on my Windows 10 PC. They are both running Atlas@home, on 2 cores on the PC and on one core on the Linux box. Tullio ID: 36206 · Reply Quote
