Hi all,
I am trying to run two functions at the same time with Parallel
Processing (pp) as following ;
import pygame
import sys
import time
import math
import pp
screen = pygame.display.set_mode((0, 0), pygame.FULLSCREEN)
timer = pygame.time.Clock()
white = True
start = time.time()
end = time.time() - start
def test1():
global end
while(end<5):
end = time.time() - start
timer.tick(4) #FPS
screen.fill((255,255,255) if white else (0, 0, 0))
white = not white
pygame.display.update()
def test2():
global end
while(end2<5):
end2 = time.time() - start
print end
ppservers = ()
if len(sys.argv) > 1:
ncpus = int(sys.argv[1])
# Creates jobserver with ncpus workers
job_server = pp.Server(ncpus, ppservers=ppservers)
else:
# Creates jobserver with automatically detected number of workers
job_server = pp.Server(ppservers=ppservers)
print "Starting PP with", job_server.get_ncpus(), "workers"
job1 = job_server.submit(test1,test2)
result = job1()
And the output is ;
Starting PP with 2 workers
Traceback (most recent call last):
File "fl.py", line 46, in <module>
job1 = job_server.submit(test1,test2)
File "/usr/lib/python2.6/site-packages/pp.py", line 402, in submit
raise TypeError("args argument must be a tuple")
TypeError: args argument must be a tuple
When I change job1 to just to see if it will run one function only;
job1 = job_server.submit(test1)
I get an output of;
NameError: global name 'end' is not defined
end variable is defined as global but I get a NameError. Anyone has an
idea what's going on ?
