hutuxian	5a80cc8431	Datafeed support reading to cuda place directly. (#19071) ... * add a place field in DataFeed to denote which place it will feed data to. * abstract the copy process in CopyToFeedTensor function * add UT for float32 type and for CUDAPlace	6 years ago
jiaqi	3f8031e256	dataset (#17973) ... (1) use channel instead of vector/BlockingQueue in Dataset，to keep same with existing implementation, and make code more readable and flexible (dataset single output channel or multi output channel). one previous memory out of limit problem is cause by not release memory after training. (2) add Record because MultiSlotType costs too much memory (80B)，fix memory out of limit problem. (3) add Channel, Archive in paddle/fluid/framework (4) change dataset from shared_ptr to unique_ptr in pybind (5) move create/destroy readers from trainer to dataset (6) move shuffle from datafeed to dataset. dataset holds memory, datafeed is only for load data and feed data to network. (7) fix thread num bug of Dataset when filelist size < thread num (8) support set_queue_num in InMemoryDataset	6 years ago
hutuxian	969e6378b9	Pipeline Concurrency (#17402) ... Add Pipeline Concurrency Train Mode: - Cpp: pipeline_trainer & section_worker - Python: PipelineOptimizer - Add a new data_feed type: PrivateInstantDataFeed - Add a test demo of pipeline trainer and the test model is gnn - Do not support win32 now	6 years ago
