Python compute cluster

Question

Would it be possible to make a python cluster, by writing a telnet server, then telnet-ing the commands and output back-and-forth? Has anyone got a better idea for a python comp

Answer 1

I think IPython.parallel is the way to go. I've been using it extensively for the last year and a half. It allows you to work interactively with as many worker nodes as you want. If you are on AWS, StarCluster is a great way to get IPython.parallel up and running quickly and easily with as many EC2 nodes as you can afford. (It can also automatically install Hadoop, and a variety of other useful tools, if needed.) There are some tricks to using it. (For example, you don't want to send large amounts of data through the IPython.parallel interface itself. Better to distribute a script that will pull down chunks of data on each engine individually.) But overall, I've found it to be a remarkably easy way to do distributed processing (WAY better than Hadoop!)
