#5041 — About Message Passing Process Communication Model and Shared Memory Process Communication Model

Hello..


About Message Passing Process Communication Model and Shared Memory 
Process Communication Model:


An advantage of shared memory model is that memory communication is 
faster as compared to the message passing model on the same machine.

However, shared memory model may create problems such as synchronization 
and memory protection that need to be addressed.

Message passing’s major flaw is the inversion of control–it is a moral 
equivalent of gotos in un-structured programming (it’s about time 
somebody said that message passing is considered harmful).

Also some research shows that the total effort to write an MPI 
application is significantly higher than that required to write a 
shared-memory version of it.



Thank you,
Amine Moulay Ramdane.
