questions about darlin

[leecy0405]

Hi muli
I have read part of the code of darlin，I can`t find the implementation of api "void run" in darlin for server and worker, it seems that only scheduler run is used?

the running long also shows:

in the log， I also can not find the logs relevant to worker and server

yeah. in this batch algorithm, the scheduler issues tasks into workers and
servers in run(), while the other nodes only need to accept calls from the
scheduler, so they have empty run().

Thanks a lot, I have realized the mechanism, thank you for paying attention~
