What are MPI communication patterns?

MPI communication patterns refer to the various ways processes communicate in parallel computing using the Message Passing Interface (MPI). They include point-to-point communication, collective communication, and more.

Can you explain point-to-point communication?

Sure! Point-to-point communication in MPI involves direct communication between two processes. It includes operations like send and receive, allowing one process to send data to another.

What about collective communication?

Collective communication involves a group of processes communicating together. Examples include broadcast, scatter, gather, and reduce operations, where data is shared among multiple processes.

How do I choose the right communication pattern for my application?

Choosing the right communication pattern depends on your application's architecture and data flow. Consider factors like data size, the number of processes, and the required synchronization.
