SIMD \< SIMT \< SMT: parallelism in NVIDIA GPUs
Programmable NVIDIA GPUs are very inspiring to hardware geeks, proving that processors with an original, incompatible programming model can become widely used. NVIDIA call their parallel programming model SIMT - "Single Instruction, Multiple Threads". Two other different, but related parallel programming models are SIMD - "Single Instruction, Multiple Data", and SMT - "Simultaneous Multithreading"
C++ FQA Lite: Defective C++
Part of C++ FQA Lite This page summarizes the major defects of the C++ programming language (listing all minor quirks would take eternity). To be fair, some of the items by themselves could be design choices, not bugs. For example, a programming language doesn't have to provide garbage collection. It's the combination of the things that makes them all problematic. For example, the lack of garbage
Parallelism and concurrency need different tools
concurrent (noun): Archaic. a rival or competitor. – dictionary.com Two lines that do not intersect are called parallel lines. – Wikipedia In this piece, I disagree with Joe Armstrong and Rob Pike, basing my argument on the differences between vending machines and gift boxes (illustrated with drawings carefully prepared in Microsoft Paint). Parallelism and concurrency are both very fashionable not
