I try with small data (~60 elements in _local_dict), and it worked.
Perhaps, there are problems with a lot of rpc call?
For real data, size of _local_dict is nearly 190000 elements - 32 workers. With each element, I called 32 times for rpc(…).
For each worker, we have to call 19000032 times for rpc(…). We have 32 workers. Hence, totally, there are 19000032*32 times for calling RPC.
Is there any problem with that?
Thanks,
