On running the sample code given in the dispy documentation def compute(n): import time, socket time.sleep(n) host = socket.gethostname() return (host, n) if name == 'main': import dispy, random cluster = dispy.JobCluster(compute) jobs = [] for i in range(10): # schedule execution of 'compute' on a node (running 'dispynode') # with a parameter (random number in this case) job = cluster.submit(random.randint(5,20)) job.id = i # optionally associate an ID to job (if needed later) jobs.append(job) # cluster.wait() # wait for all scheduled jobs to finish for job in jobs: host, n = job() # waits for job to finish and returns results print('%s executed job %s at %s with %s' % (host, job.id, job.start_time, n)) # other fields of 'job' that may be useful: # print(job.stdout, job.stderr, job.exception, job.ip_addr, job.start_time, job.end_time) cluster.print_status()

I get the following output

2017-03-29 22:39:52 asyncoro - version 4.5.2 with epoll I/O notifier

2017-03-29 22:39:52 dispy - dispy client version: 4.7.3

2017-03-29 22:39:52 dispy - Port 51347 seems to be used by another program

And then nothing happens. How to free the 51347 port?

If you are under Linux, run sudo netstat -tuanp | grep 51347 and take note of the pid using that port.

Then execute ps ax | grep <pid> to check which service/program is running with that pid.

Then execute kill <pid> to terminate the process using that port.

Please check which process is using the port before killing it just in case it is something that you should not kill.
