<div class="gmail_default" style="font-family:arial,helvetica,sans-serif">The setup script should start a persistent coaster service and connect to the nodes on amazon, start workers, and generate a sites.xml file</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">
that would let your swift scripts run across the amazon nodes. You shouldn't have to make changes to the sites.xml.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">
Alternatively, you could try using the beta release of swift, Swift 0.95 RC6 with the new cloud mechanism:<br></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"><a href="https://github.com/swift-lang/swift-on-cloud/tree/master/aws" target="_blank">https://github.com/swift-lang/swift-on-cloud/tree/master/aws</a></font></div>
<div class="gmail_default"><font face="arial, helvetica, sans-serif"><br></font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif">That will set you up with a headnode on AWS with a few worker nodes that you define, with everything setup to run swift.</font></div>
