parallel-python error: RuntimeError("Socket connection is broken")
- by user288558
I am using a simple program to send a function:
import pp
nodes=('mosura02','mosura03','mosura04','mosura05','mosura06',
'mosura09','mosura10','mosura11','mosura12')
nodes=('miner:60001',)
def pptester():
js=pp.Server(ppservers=nodes)
js.set_ncpus(0)
tmp=[]
for i in range(200):
tmp.append(js.submit(ppworktest,(),(),('os',)))
return tmp
def ppworktest():
import os
return os.system("uname -a")
the result is:
wkerzend@mosura:/home/wkerzend/tmp/ppython_test>ssh miner "source ~/coala_python_setup.sh;ppserver.py -d -p 60001"
