示例1: adder
# 需要导入模块: from pathos.multiprocessing import ProcessingPool [as 别名]
# 或者: from pathos.multiprocessing.ProcessingPool import ncpus [as 别名]
# pickle fails for nested functions
def adder(augend):
zero = [0]
def inner(addend):
return addend+augend+zero[0]
return inner
# build from inner function
add_me = adder(5)
# build from lambda functions
squ = lambda x:x**2
# test 'dilled' multiprocessing for inner
print "Evaluate 10 items on 2 proc:"
pool.ncpus = 2
print pool
print pool.map(add_me, range(10))
print ''
# test 'dilled' multiprocessing for lambda
print "Evaluate 10 items on 4 proc:"
pool.ncpus = 4
print pool
print pool.map(squ, range(10))
print ''
# test for lambda, but with threads
