Hello Alan,

thank you for your answer.

I think both.
The most important need for me seems to be to have the ability that 
individual steps within a workflow run on our SGE cluster transparently 
for the user which uses the workflow. So those workflow steps should be 
executed on nodes of the SGE cluster, the whole handshake for the usage 
of those steps should be done by the Taverna system itself.

If that's possible, and I hope I can find a solution for that approach, 
I don't see limitation to create whole workflows running on the SGE grid 
too, except the "administration" of those workflows which should run on 
a separated local PC where the Taverna GUI is running.

Or maybe later a commandline tool for the same purpose running on a 
local PC AND/OR running on the SGE Grid cluster as cronjob.

My aim is to build Taverna workflows which can make use of our SGE grid 
for the computational demanding parts transparently (invisible) in the 
background. Depending on the concrete workflow this could mean that all 
workflow steps should be executed on the SGE grid.

I couldn't find any SGE Taverna solution so far, it seems to me SGE 
isn't supported by Taverna!?
