Right now it only runs as a single process and uses one CPU core out of the 18, which makes it very slow for a 5 million node domain. I use a Windows 10 system with admin rights. I have used the Admin tool to setup all the MPI options, confirmed that they are running (through services.msc) and successfully registered the user as (COMPUTERNAME\UserName). I have also turned UAC off according to the documentation. Does anyone know if I need to perform any additional steps, or is AutoGrid5 able to compute in parallel at all? Thanks.
