Mutexes - . Reader/writer locks - . Condition variables - . Semaphores - . Tokens - . Adaptive lockings - -There are additional tests that measure the memory bandwidth under the -following conditions: - - . User memory-to-memory copying of data within a single thread - . User memory-to-kernel-to-user memory copying via pipes - between separate processes, as well as between separate - threads in the same process - -There are many options available for this module that can be put into -svc.conf files.
