Chen Weihang	0b54d54fd8	Fix index overflow bug of the CUDA kernel loop increment (#25435) ... * fix softmax_with_cross_entropy cuda kernel overflow bug, test=develop * replace old macro & for condition, test=develop * polish details, test=develop	5 years ago
Huihuang Zheng	12542320c5	Replace TemporaryAllocator by CUDADeviceContextAllocator (#18989) ... TemporaryAllocator is a singleton used for allocating memory for Cudnn. Since it is a singleton, we can delete it for better performance in memory. We replace TemporaryAllocator by CUDADeviceContextAllocator and CUDADeviceContextAllocation, which uses stream callback to delete the memory allocated for the stream to avoid singleton. Also added data_feed_proto to operator to fix CI in CPU compilation	6 years ago
