How can I suspend my workflow execution and resume it the next day?

Although we have a "Pause" button on the execution screen of Taverna, it might not work as you expect, and it only works properly for some services.

If your problem is that the workflow takes long to run, Taverna is running on your laptop, and you want to go home for the weekend, what you might want to do instead is to save the workflow and its input data to files, and run it using 'screen' on some Linux workstation or server. This involves 'Executing a workflow outside of Taverna'. Unfortunately this method does not give you any progress feedback as the workflow is executing, and is not integrated from the Taverna GUI, as it must be run on the command line.

Under development by the myGrid team is a Long running workflow service which allows you to submit a workflow to run on an external server. The workflow will be in a queue, and you can connect to the server from Taverna (or a web browser) to check the status and results.

An early version of this will probably be available in Spring 2007.
