How many workers can one supervisor provide?


Client often find one problem, “Failed to submit a job, the number of free worker isn’t enough”, So what’t the algorithm of generating worker list.


Please refer to


 Define the amount of workers that can be run on this machine. Each worker is assigned a port to use for communication

 if supervisor.slots.ports is null, 
 the port list will be generated by cpu cores and system memory size 
 for example, 
 there are cpu_num = system_physical_cpu_num/supervisor.slots.port.cpu.weight
 there are mem_num = system_physical_memory_size/(worker.memory.size * supervisor.slots.port.mem.weight) 
 The final port number is min(cpu_num, mem_num)
