Boot Mechanism

The simulator system image is booted with a utility called loader which:

1. Allocates 32 Megabytes of virtual memory for the simulator on the host.

2. Copies the system image to the allocated memory.

3. Configures the remote IPC-oriented UDP port and the IP address based on information in the site configuration file, site_number.conf.

4. Jumps to the entry point of the system image and runs the simulator.

Figure 1-1 illustrates the virtual address space of the UNIX process after loading the system image.
