CUDA kernel launches are inherently asynchronous: the CPU writes the kernel and its parameters into the command queue and returns immediately, while actual execution is carried out later by the GPU scheduler.

Unverifiedcuda-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80% similarUnverifiedThe system supports both CPU and CUDA operating modes, and automatically selects compute resources based on the running platform.74% similarUnverifiedCUDA 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.73% similarVerifiedThe core of CUDA includes the CUDA runtime and driver layer, the PTX intermediate instruction set, and companion libraries such as cuDNN, cuBLAS, and TensorRT.72% similarUnverifiedCUDA kernels require time-consuming operations such as JIT compilation and kernel selection upon first execution, causing abnormally high inference latency for the first batch, which can be mitigated by using dummy inputs to trigger initialization in advance.72% similar
