Use thread debugging tools to detect deadlocks and resolve them by avoiding nested locks and using deadlock detection mechanisms. Use the Data Race Analyzer to detect data races and resolve them by moving write operations into critical sections or using atomic operations. Use performance analysis tools to measure context switch frequency and resolve excessive overhead by reducing the number of threads, using thread pools, and offloading tasks.
