The Evolution of High-Performance Computing on GPUs
The development of high-performance computing on GPUs has significantly transformed since the early 90s, as shared by an industry expert. Initially, the focus was on optimizing GPUs for graphics rendering, which restricted their computational capabilities. Through pioneering efforts at companies like Peakstream, the GPUs' performance was enhanced to support complex calculations, enabling impressive speed improvements over traditional CPUs. This growth catered to a wide array of applications, including finance and climate modeling, but challenges persisted in terms of usability and debugging due to the GPUs being primarily designed for rendering rather than computation.
