ompgetwtime
ompgetwtime is a function used in OpenMP to retrieve the current value of the high-resolution timer. OpenMP is an API that supports shared-memory multiprocessing programming in C, C++, and Fortran. The timer provided by ompgetwtime is intended for measuring elapsed time for performance profiling and benchmarking. It typically returns a double-precision floating-point number representing the elapsed time in seconds since some arbitrary starting point.
The specific resolution and accuracy of the timer are system-dependent, but it is generally designed to be
When using ompgetwtime, one common pattern is to record the start time before a section of code,
