Under-the-hood look at #GPU architecture and performance that Machine Learning people might find interesting. I originally gave this talk at Unity's internal ML Workshop in Seattle. Please share, if you find it useful.

GPU - 6TB of RAM, 1PB/s bandwidth and 15KW by 2035. The whole contraption will be made from many dies combined on a huge interposer!

A lot of wisdom about unit tests in this thread:.

Unit tests have lots of advantages, but cons are ignored:.- Code must be split to testable parts. Often requiring more interfaces, which add code bloat and complexity. - Each call site is a dependency. Test case = +1 dependency. Added inertia to refactor and throw away code. .

Radix sort (LSD) wins with half the memory access comparing to others!. Also handy use of sound to compare different sort algos ;).
