[Swift-user] how to run swift script against a local cluster

[Jiao Lin]

Hello,

We just learned about swift and are trying to use swift to run computations on a local cluster. I was trying to follow the note at http://rmcgibbo.github.io/blog/2013/06/03/setting-up-swift/

When trying to run a simple echo command at a local cluster using coaster provider, I got an error:

$ swift echo.swift
Swift 0.94.1 swift-r7114 cog-r3803

RunID: 20140202-1140-yyytkso6
Progress:  time: Sun, 02 Feb 2014 11:40:58 -0800
Execution failed:

        echo, echo.swift, line 11

It seems it failed when globus is trying to get certificates? Is it necessary to install some kind of globus service on the cluster?

I wonder what kind of requirements are there for the cluster? The cluster has java 1.7 installed:

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Your help is much appreciated.
