Are URLs supported by the current Swift? That is what I am doing with
the data caching in Falkon, but to the compute node (to local disk).
If Swift were to do this to the compute site (i.e. to GPFS), then you
also need a way to keep track of what files are at what site, so then
other sites can then retrieve the files directly from peer sites,
rather than going back to the submit host (what would currently happen
on a cross site run). Is this mapping handled in Swift at the moment?
And if so, does it use RLS, or something similar, or an in-house
solution? I just haven't heard of this functionality within the
context of Swift so far, and am curious what is there and what is not.<br>

<pre wrap="">In the MolDyn app, the swift runtime is 'customised' (cough) so that it

If those intermediate files were mapped to remote files on the execution
site (eg as gridftp URLs), what would happen?
Would swift try to stage back those files to their submit-side locations
which would actually be on the compute site?

Yes, I think so.
