UnverifiedThe zero-copy mechanism leverages CUDA's mapped pinned memory or unified memory features; memory allocated via cudaHostAllocMapped can be accessed simultaneously by both the CPU and GPU, eliminating the copy step.73% similarUnverifiedA CUDA stream is an asynchronous execution queue on the GPU; operations in different streams can execute concurrently and are a key mechanism for overlapping computation and data transfer.72% similarUnverifiedcuda-checkpoint能将GPU上运行进程的完整状态（包括显存数据、CUDA上下文、设备句柄）序列化保存至磁盘并快速还原至GPU继续运行71% similarUnverified时间切片没有内存隔离和故障隔离，共享同一GPU的进程运行在同一内存空间，一个错误的CUDA调用可能使整块GPU所有任务崩溃70% similarUnverifiedCUDA Graph is a performance optimization technology introduced by NVIDIA in CUDA 10 that reduces CPU-GPU synchronization latency through a record-and-replay mechanism.67% similar
