What are the key tuning parameters for OpenMP?
The key tuning parameters for OpenMP include the number of threads, scheduling type, and the chunk size.
How do I choose the right number of threads?
The right number of threads depends on your hardware and the nature of your workload. Generally, you should start with the number of physical cores.
What is the difference between static and dynamic scheduling?
Static scheduling assigns iterations to threads before execution, while dynamic scheduling assigns them at runtime, which can help balance load.
Can you explain chunk size and its impact?
Chunk size determines how many iterations are assigned to each thread at a time. A smaller chunk size can improve load balancing but may increase overhead.
