UnverifiedThe GPU memory hierarchy from fastest to slowest is: registers, L1 cache/shared memory, L2 cache, global memory (VRAM).71% similarUnverifiedGPU上下文切换需保存完整GPU状态(包括寄存器文件、共享内存和L1缓存),数据量可达数百MB,而CPU上下文切换仅需保存几KB71% similarUnverifiedTraditional AI chips (GPUs or TPUs) store model weights in memory and compute units read and execute them on demand, with a large amount of time and energy consumed in weight transfer.70% similarUnverifiedFor modern CPUs and GPUs, memory bandwidth is often the true bottleneck for inference speed rather than the compute units' arithmetic throughput, which is why quantization can bring speed improvements.69% similarUnverifiedA new storage-inspired memory solution could enable a single GPU's usable memory capacity to grow to the multi-terabyte level69% similar
