"Allocator cache flushes"指的是内存分配器缓存的清空操作。当缓存被清空时,之前存储在缓存中的内存块将被释放回系统,不再用于快速重新分配。这通常发生在内存压力较大或为了回收不再需要的内存时。 3. 分析自上一个step以来可能发生allocator cache flushes的条件 在PyTorch中,allocator cache flushes可能发生在以下条...

CUDACachingAllocator是PyTorch中一个GPU显存缓存分配器,它可以缓存从GPU分配的内存,管理框架内部数据的分配释放,减少频繁的cudaMalloc和cudaFree开销。 CUDACachingAllocator的实现原理是通过一个内存池来管理GPU内存,提供分配释放接口,并且通过内存分配策略减少内存碎片,提高内存利用率。除了分配释放接口,CUDACachingAllocator还...
