问题
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?
回答1:
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.
