      * test passes
      
      * notes
      
      * Using C++-side flatten and unflatten functions
      
      * Adding csrc
      
      * Persistent synchronization event so it doesn't need to be created and destroyed each time
      
      * Interop with parameter flattening in SSD
      
      * Added deterministic option to imagenet main.py
      
      * Adding options to split gradient averaging and allreduce in pure fp32
      
      * Fixing allreduce_maybe_retain call
      
      * Fixing allreduce_fallback
      
      * Also sync active_i_buckets from rank 0
      
      * Making retain_allreduce_buffers compatible with/orthogonal to delay_allreduce=True|False
      
      * Correcting syntax error, now all seems to work with SSD
      
      * Optional cpp extension build
      
      * Add mixed precision adam optimizer (#59)
      
      * Add FusedAdam Optimizer to Apex that places all the math into a cuda kernel.
      
      * Added fixes to fused_adam to get it to work with network.
      
      * wip work on python interface for adam with options
      
      * fix dispatch for halfs, add python options to handle optional half gradients and params
      
      * cleanup, get rid of grid-stride loop
