[kepler-users] Running Workflows in offline Mode With Kepler

Just a quick note: One way to achieve this functionality (in a very
simple way) is to run Kepler directly at the server (e.g., using
ptexecute) as a background process ...  This would be a "poor man's"
version of what you are asking for.  Some limitted monitoring could be
"built in" to the workflow or possibly using some of Ptolemy's logging
capabilities.

Also, there are some workflows defined in Kepler (TSI, etc.)  that are
designed to perform what you are describing.  That is, the workflow
itself describes a control-process for the execution of distributed
and long running (external) processes -- having special purpose
logging, monitoring, and adaptation mechanisms (e.g., for fault
tolerance).
