topic Thread Checker and shared locks? in Intel® Moderncode for Parallel Architectures https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Thread-Checker-and-shared-locks/m-p/874451#M3124 <P>I'll look into VTune.</P> <P>Are you suggesting that Thread Checker alone cannot do what I want through its API? That would be unfortunate since shared locks are common. pThreads has them, but we're rolling our own mutex locks.</P> Thu, 11 Mar 2010 00:38:08 GMT ronmak 2010-03-11T00:38:08Z Thread Checker and shared locks? https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Thread-Checker-and-shared-locks/m-p/874449#M3122 <P>Is there support for shared (read) locks in the user-level synchronization API? I'm developing a Linux application where we do our own non-pThread and non-OpenMP mutexes. The four methods __itt_notify_sync_{prepare, cancel, acquired, releasing} appear to support only exclusive (write) locks. Am I missing something?</P> Tue, 09 Mar 2010 00:19:10 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Thread-Checker-and-shared-locks/m-p/874449#M3122 ronmak 2010-03-09T00:19:10Z Thread Checker and shared locks? https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Thread-Checker-and-shared-locks/m-p/874450#M3123 What you're missing is that expert advice on VTune and Thread Checker should be more readily available on the VTune forum.
