From Master Foilset for HPC Achitecture Overview CPS615 Basic Simulation Track for Computational Science -- Fall Semester 98. by Geoffrey C. Fox
1 Process: virtual address space plus one or more threads of control
2 Portions of address spaces of processes are shared
3 Writes to shared address visible to other threads (in other processes too)
