Vector utilities

bench_vector_utils

This uses vector operations to do performance tests. It yields the time it took to compute, the bandwidth, and the GigaFlops.

Test 1: adds two vectors

Test 2: multiplies a complex scalar by a vector

Test 3: multiplies a real scalar by a vector

Test 4: vector plus real scalar times vector

Test 5: vector plus real complex times vector

Test 6: real scalar times vector plus real scalar times vector

Test 7: complex scalar times vector plus complex scalar times vector

Test 8: finds the norm of a vector

Test 9: computes the scalar product of two vectors

Test 10: computes the gamma5 matrix times a vector
