1.Verify correctness using BLAS-Tester
2.Using the built-in benchmark to verify performance, the performance of float and doule type improved by about 60% and about 40% respectively.The test command is:
export OMP_NUM_THREADS=1;numactl -C 10 -l ./sgemv.goto 3000 4000 100
export OMP_NUM_THREADS=1;numactl -C 10 -l ./dgemv.goto 3000 4000 100
