Julia version of multithreading TEST_CPU Fortran.uk Polyhedron Fortran Benchmark : that single thread (https://openbenchmarking.org/test/pts/polyhedron&eval=111335e02dea1589bab7a9564f8efef17d907dcb#metrics) Implemented by: David Frank  [email protected], original gauss Tim Prince   [email protected], Crout James Van Buskirk  [email protected], Jos Bergervoet [email protected]. NOW gauss single thread with looping repetition OpenMP, crout single thread with looping repetition OpenMP, crout multi thread, and implementing with vendor blas lapack instead building own. by default as same as phoroix is 1000 repetition dual inversing 250x250, and 2000x2000 dual inversing, and check the difference.

Example: ryzen 3900x
