- Fast restore during epochs: When the parameter server is re-usable, the local session in each worker is fast-restored from the local saved graph file, instead of from the graph file from HDFS. SparkSession need not broadcast the session in the following epochs.
- Fix the IOLoop bug. Fix the bug when the IOLoop and the parameter server is sometimes not properly closed in some error cases.
- Support re-usable parameter server. Parameter server can be reused by for multiple training epochs.
