What are the differences between MPI and OpenMP?
MPI (Message Passing Interface) is designed for distributed memory systems, while OpenMP is for shared memory systems.
Can you explain how they handle parallelism?
Sure! MPI uses message passing for communication between processes, while OpenMP uses shared variables and threads.
Which one is better for large-scale applications?
It depends on the application. MPI is generally better for large-scale distributed systems, while OpenMP is simpler for shared memory.
Are there any scenarios where I would use both?
Yes, in hybrid programming, you can use MPI for inter-node communication and OpenMP for intra-node parallelism.
