c6fc20c Implement cosdistance/cosdistance_drive in native CUDA code to optimize the speed and save memory 27 February 2017, 09:36:09 UTC
a6e13ce Packing matries in V1 Aggregation Packing aggregated matrixes into continuous buffer so less MPI operations are used. Usage: Introduce a configurable threshold size (units = KB) and only pack gradients into a continous buffer whose total size is below the threshold. This is to avoid possible memory overflow. The default threshold size is 32KB. To change this value, specify "packThresholdsizeInKB=value" (e.g. 2048 for 2MB) in train/eval config file. Notes: acquire continous buffer only if NCCL is not supported Fallback to normal execution if not enough extra continous memory available change reduce all to unblocking reduce all SimpleDistAggregate: Broadcast the aggregated headers to all nodes Configurable threshold size to pack gradients in a buffer simpleAggregator: pack the gradient into continous buffer if its size is less than PackThresholdSize Add all constant definitions to a header file in Common 25 February 2017, 18:53:48 UTC

49aeeae Update README.md 23 February 2017, 21:46:18 UTC
ef3aa02 CNTK v2 library: Fixed a couple of tutorials that were using numpy imnterop to properly specify the dynamic axes of inputs; earlier the models were specifying inputs to have both sequence and dynamic axes though the fed numpy array data did not account for the sequence axis causing the batch dimension to be wrongly interpreted as the sequence dimension. This was working earlier due to a bug in interpreting numpy data which always interpreted the leading axis to be the bacth axis regardless of the actual dynamic axis the input has; fixing that bug exposed the issue with these notebooks 23 February 2017, 21:39:36 UTC
