What are some effective tools for debugging parallel processing?

There are several tools you can use for debugging parallel processing, such as GDB, Valgrind, and Intel Inspector. Each has its strengths depending on your specific needs.

Can you explain how GDB works for parallel debugging?

GDB allows you to debug multi-threaded applications by attaching to processes and inspecting thread states. You can set breakpoints, step through code, and examine variables across threads.

What about Valgrind? How does it help with memory issues?

Valgrind is great for detecting memory leaks and errors in parallel applications. It provides detailed reports on memory usage and can help identify race conditions.

Are there any specific features in Intel Inspector that are useful?

Yes, Intel Inspector offers advanced memory and threading error detection, along with performance profiling, which can be very helpful in optimizing parallel applications.
