The number of clients. If specified, the executor factory
function returned by local_executor_factory will be configured to have
exactly num_clients clients. If unspecified (None), then the function
returned will attempt to infer cardinalities of all placements for which
it is passed values.
max_fanout
The maximum fanout at any point in the aggregation hierarchy. If
num_clients > max_fanout, the constructed executor stack will consist of
multiple levels of aggregators. The height of the stack will be on the
order of log(num_clients) / log(max_fanout).
clients_per_thread
Integer number of clients for each of TFF's threads to
run in sequence. Increasing clients_per_thread therefore reduces the
concurrency of the TFF runtime, which can be useful if client work is
very lightweight or models are very large and multiple copies cannot fit
in memory.
server_tf_device
A tf.config.LogicalDevice to place server and other
computation without explicit TFF placement.
