 something regularly, to a schedule dictated by you, no matter how heavily loaded the system.  RTAI comes in two parts:  a set of patches for your kernel and a library you can link your programs against which allows them to become realtime tasks.  It may feel like you're running your program under Linux just like any other normal user-mode program, however under the hood you are taking full control of the hardware, and any other processes will only run as the remaining CPU time permits. something regularly, to a schedule dictated by you, no matter how heavily loaded the system.  RTAI comes in two parts:  a set of patches for your kernel and a library you can link your programs against which allows them to become realtime tasks.  It may feel like you're running your program under Linux just like any other normal user-mode program, however under the hood you are taking full control of the hardware, and any other processes will only run as the remaining CPU time permits.
