Computation has increased 17 orders of magnitude over the sixty years I have been visiting and celebrating gains in computational environments. The first “supercomputers” ran at a million ops per second and in 2021 the fastest computers operates at exa-ops or 1018ops with gains of 10 million occurring in the last twenty-five year by exploiting parallelism. The relatively small community who have produced these gains through parallelism. Gains must be discovered at every level of the hardware and compilers to the applications and supporting algorithms. In the beginning, the challenge was to obtain enough computing resources to solve some small aspect of a scientific or engineering problem, not the problem is really imagining the problems that can exploit these potentially infinite resource computing environments.
