show the different states of various processes, CPUs, and other resources along
the time axis using the stored state values. In the Resource view, for example,
green states denote the times that CPUusedinuserspacemodeinwhicha
process utilizes the CPU for its internal instructions, while blue states show the
times that CPU is executing system calls. Using the Resource the Control Flow
views simultaneously, we can observe that the Xorg process is doing a system call
on CPU4. In parallel, the Compiz process requests access to the same processor
CPU4 with an event sched wakeup . As we can see, this process changes its state
from WAIT (yellow) to WAIT FOR CPU (orange).
