3.torch.cuda.empty_cache()这个代码是用来释放GPU reserved memory显存的,如果调用完函数之后,有的tensor并不会被释放,用这个。这个对我来说有用,但我没想到是我最终还需要第5个解决方案。 可以用下面这个代码在函数调用前执行一次,函数调用后使用torch.cuda.empty_cache()清理显存再执行一次,可以观察到GPU reserv...
global memory的分配就是之前频繁使用的cudaMalloc,释放使用cudaFree。global memory驻留在devicememory,可以通过32-byte、64-byte或者128-byte三种格式传输。这些memory transaction必须是对齐的,也就是说首地址必须是32、64或者128的倍数。优化memory transaction对于性能提升至关重要。当warp执行memory load/store时,需要...

使用cudaMalloc和cudaFree管理内存分配会导致 GPU 在所有正在执行的 CUDA 流之间进行同步。 Stream Order Memory Allocator 使应用程序能够通过启动到 CUDA 流中的其他工作(例如内核启动和异步拷贝)来对内存分配和释放进行排序。这通过利用流排序语义来重用内存分配来改进应用程序内存使用。分配器还允许应用程序控制分配器...
