[Swift-user] Passing GRAM parameters

[Andriy Fedorov]

Hello,

1. I have a workflow, which contains an MPI-parallelized component. I
haven't seen a reference on how explicitly parallel jobs can be
launched in the Swift guide. Is this functionality implemented, or
this requires extending Swift (writing a new site selector, maybe?)

2. How can I specify the walltime for a job? I see a reference to
GLOBUS::maxwalltime in the swift.properties comments, which seems to
be related, but no explanation. The ability to specify walltime seems
to me a basic functionality.

I know these two can be specified in an RSL for GRAM, but can I do it
with Swift? If not, is it very difficult to access the RSL passed to
GRAM?

Thanks
