使用dispy将工作分配到ec2实例

Question

我尝试使用dispy将工作分配到ec2实例。在

我跟踪了：

Using dispy with port forwarding via ssh tunnel

http://dispy.sourceforge.net/dispy.html#cloud

但是它不会去任何地方，客户端脚本被挂起，服务器节点没有接收到任何东西。在

我现在拥有的是：

从我的机器：

ssh -i mypemfile.pem -R 51347:localhost:51347 ubuntu@ec2-52-30-185-175.eu-west-1.compute.amazonaws.com

然后在远程计算机上：

^{pr2}$

我得到：

2016-02-03 18:38:39,410 - dispynode - dispynode version 4.6.7
2016-02-03 18:38:39,414 - asyncoro - poller: epoll
2016-02-03 18:38:39,417 - dispynode - serving 1 cpus at 172.31.26.18:51348
2016-02-03 18:38:39,417 - dispynode - tcp server at 172.31.26.18:51348
2016-02-03 18:38:39,422 - asyncoro - waiting for 2 coroutines to terminate
Enter "quit" or "exit" to terminate dispynode,
  "stop" to stop service, "start" to restart service,
  "cpus" to change CPUs used, anything else to get status:

在我运行的客户机上：

import dispy
def f(x):
    return 2*x
cluster = dispy.JobCluster(f,nodes=['ec2-52-30-185-175.eu-west-1.compute.amazonaws.com'],ext_ip_addr='localhost')
job = cluster.submit(2)
print('result: %s' % job())

什么也没发生，只是卡住了。 谢谢
