the image above shows the timings for each function
 
matmul_0 - represents serial version
 
matmul_1 - represents serial version with reverse logic
 
matmul_2 - uses cilk_for
 
matmul_3 - uses cilk_for and reducer hyperboject
matmul_4 - uses cilk_for, reducer and vectorization
 
 
===Advanced hotspot analysis===
matmul_4 - uses cilk_for, reducer and vectorization
===Locks & Waits===
===HPC Performance Characterization===* Best for locating causes of low concurrency, such as heavily used locks and large critical sections.* Locks are when threads are waiting too long on synchronization objects.* Uses user-mode sampling and tracing collection to identify processes. ==Microarchitecture==* This analysis shows time spent waiting on synchronizations.
===General Exploration===
