Goal

• Understand the issues in designing message-passing APIs and how to implement them

Reading Assignments

• MOS 2.3.8, 8.2.1-8.2.4

Issues

• send(destination, msg) and recv(source, msg) are generic forms of the message passing primitives.  If you are responsible of designing a message passing API, what should you consider?  In particular, what should the syntax of destination,source and msg be?  What should the semantics of the message passing primitives?

• How would you implement the two  message passing primitives?  Our focus is on how to deal with synchronization and buffer management.   Write pseudo code to show your implementation ideas.
