Merits of Shared Memory Programming

  • Global address space gives a user-friendly programming perspective to memory.
  • Data sharing among processes is both fast and uniform due to the proximity of memory to CPUs.
  • No use to specify explicitly the communication of data between processes.
  • Insignificant process-communication overhead.
  • More easier and intuitive to learn.

Drawbacks

  • Complex to manage data locality.
  • Not portable.
  • Scalability is limited by the number of open pathways to memory.
  • User is liable for specifying synchronization, example:- locks.
