What are the differences between MPI and OpenMP?
MPI (Message Passing Interface) is used for distributed memory systems, while OpenMP is for shared memory systems.
Can you explain how they handle parallelism?
MPI uses message passing to communicate between processes, while OpenMP uses shared variables and threads.
Which one is better for high-performance computing?
It depends on the architecture; MPI is better for large clusters, while OpenMP is suitable for multi-core processors.
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.
