Single instruction, multiple threads

Single Instruction, Multiple Threads (SIMT) is a parallel computing architecture used primarily in graphics processing units (GPUs) and other such highly parallel computing environments. SIMT is closely related to Single Instruction, Multiple Data (SIMD), but with a key distinction that allows for more flexibility in thread execution. Here’s a breakdown of the key concepts: ### SIMT Characteristics: 1. **Single Instruction**: In SIMT, a single instruction is issued to multiple threads for execution.
