> In preparation of these experiments, it might be very useful to extend the parameter
server and SystemML {{-stats}}tool to keep track where we spent how much time (e.g., time
in compute gradients, aggregation, copying of matrices, slicing of batches). This would allow
us to understand the bottlenecks better and address them in a systematic manner. Please have
a look into {{org.apache.sysml.utils.Statistics}}. We could show a few summary statistics
for the parameter server if at least one paramserv function was executed.
