A SIMD unit can have up to 10 wavefronts in flight at once. Each wavefront contains 64 threads. Hence a SIMD unit can have up to 640 threads in flight at once (in multiples of 64). indians in russian army https://balverstrading.com

In the 1900s, an astrophysicist named Johannes Hartmann devised a method of measuring the ray aberrations of mirrors and lenses. The Hartmann test used a metal disk in which regularly spaced holes had been drilled.
