SIMT
Single Instruction, Multiple Threads, the core computing architecture of GPUs. Equipped with thousands of general-purpose cores, it excels at highly parallel, high-throughput floating-point matrix operations.
Timeline (last 90 days)
Under the GPU's SIMT execution model, control flow divergence (warp divergence) can cause a sharp drop in performance
GPUs adopt a SIMT (Single Instruction, Multiple Threads) architecture, which requires a high degree of regularity in data and tasks.
In the SIMT execution model of GPUs, when threads within the same warp (typically 32 threads) take different branches, warp divergence occurs, causing some threads to sit idle and wait.
A GPU warp typically consists of 32 threads; when threads within the same warp take different branches, warp divergence occurs, causing some threads to idle and wait, reducing parallel efficiency.
