Detailed Description

Tests and measures timings for matrix-matrix multiplication using BLAS and compares to a naive implementation, for rectangular matrices.

The idea is to run this linking to different BLAS variants with and without threading inside the BLAS gemm routine, to see how much speedup can be achieved from threading.
