I don't know for certain.
As far as I know, what actually happens is similar to c.) in your list.
When the service is stopped, the thread stops immediately. But, the
"heartbeat" from the executor to the manager also stops, which informs the
manager that the thread wasn't completed and it then finds another executor
to use.
Is it a hack? Are there better ways to do it?... maybe. But it works, it's
transparent, and the bandwidth cost is nil.

Hello everyone,
Just out of curiosity, has anyone encountered a situation where a grid
thread is interrupted. Does it finish executing on a different node? I
can't seem to find any information about this.
In more detail...
Say that you have a Manager set up with 2 Executors. Both Executors are
set to run in dedicated mode as a windows service. A user then submits a
single GThread, which the Manager distributes to Executor1 to run.
Executor1 starts to run the thread, but before it can complete, someone on
Executor1 attempts to stop the Alchemi Executor Service.
What happens now?
a) Executor1 immediately stops, and the thread is never completed?
b) Executor1 waits until the thread is finished to stop the service?
c) Executor1 immediately stops, alerts the Manager that it cannot complete
the thread, and the Manager sends the thread to Executor2?
d) Any other options?
I'm hoping that someone can tell me that it's not a). b) would be ok, and
c) would be much better.
Thanks for any help in this matter,
-Matt
