Unverified50% confidenceFactExact time
CUDA VRAM is a separate memory pool on an NVIDIA GPU managed by the driver; once allocated it is not automatically returned to other processes, so when two model processes request VRAM one after the other, if the one that loads first does not explicitly release it or clear the cache, the later one will hit out of memory or be forced to use a tiny batch size.

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.78% similarUnverifiedNVDEC is a dedicated hardware decoding engine in NVIDIA GPUs that is independent of CUDA cores; the decoding process does not occupy GPU compute units and can be executed in parallel with inference.77% 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77% similarVerifiedCUDA Graph is a performance optimization technology introduced by NVIDIA in CUDA 10 that reduces CPU-GPU synchronization latency through a record-and-replay mechanism.76% 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75% similar
