Hi,
i'm trying to use the python multiprocessing module to make my script
"multi-threaded".
However every time it tries to start a new process it loads up the "output
window" with command line on how to load the maya batch process.
When I close the window the process closes as well and the function is
never called or it locks up.
Unfortunately I have no idea how I can pass command line info from the
multiprocessing function.
So my question is:
How can I load a multiprocessing process without having the output window
pop up and the process running properly.
Any help would be much appreciated.
(I was thinking of running my code inside of a different interpreter but I
have no idea on how to go at it)
Example function: (it works fine in any other standard python (2.6)
interpreter ).
from multiprocessing import Pool
from time import time
## Simple func to eat up cpu power.
def whileFunc(z):
while z < 1000000:
z += 1
return z
## We have to work in __main__ else in some os versions the threads become
unsafe
if __name__ == "__main__":
## Get current time
currtime = time()
## How often to run (just a test value)
N = 1000
## Just a list with 1s
myList = [1]*N
nrOfProcessors = 8 #16
## Set our pool of processors
po = Pool(nrOfProcessors)
## create the threads
res = po.map_async(whileFunc, myList)
print 'This value below should be a 1000:'
## The "res.get()" getting of the result actually starts the threads
(surprisingly enough.)
## This is also where maya will open up the Output Window and in some
cases lock up.
print len(res.get())
print 'time elapsed:', time() - currtime
