Overview
This P/R adds an advanced model-parallel interface
chainermn.functions.all_to_all, which enables forward/backward all-to-all computation.Note
Unlike
chainermn.functions.recv, this interface does not needdelegate_variablesince it has input variables.If you would like to define a complicated model which has multiple independent computational components on one process, you can link the former component to the inputs of
all_to_allbychainermn.functions.pseudo_connect.
