我尝试使用PP时遇到了多个问题。我正在运行python2.6和pp 1.6.0 rc3。使用下面的测试代码：在分配之前引用的局部变量'sresult'
import pp
nodes=('mosura02','mosura03','mosura04','mosura05','mosura06',
'mosura09','mosura10','mosura11','mosura12')
def pptester():
js=pp.Server(ppservers=nodes)
tmp=[]
for i in range(200):
tmp.append(js.submit(ppworktest,(),(),('os',)))
return tmp
def ppworktest():
return os.system("uname -a")
给了我以下结果：
In [10]: Exception in thread run_local:

任何帮助是极大的赞赏。
我不知道PP，但考虑到在库中发生异常，这可能是一个错误。只要您的代码符合API PP指定的任何内容。尝试升级或降级PP，看看会发生什么...... – 2010-04-11 06:40:55
