This pull request adds documentation on how to enable and use OpenMP for parallel sorting in the project. It explains the configuration steps, performance benefits, and thread control options.
Documentation Updates:
README.mdtitled "Build using OpenMP." This section details how to enable OpenMP support using the-Duse_openmp=trueflag in Meson, describes potential performance improvements (up to 3x speedup), and explains how to configure the number of threads using theOMP_NUM_THREADSenvironment variable. It also specifies that OpenMP-based routines are applied to large arrays where threading is beneficial.
