Hey Anh,
I just took a quick peek at it (gotta get to class here) but there is a
System.Net.Sockets.SocketException: No such host is known
showing up.
Try to ping the executors from the manager and see if that works.
Also, there is a bug in the manager/executor code where only the computer
name of the executor is stored in the database, not the whole FQDN. So if
an executor is named executor1.domain.edu, then only "executor1" is stored
in the database. This may be what's causing you problems. You can get
around this by putting an entry in C:\Windows\system32\drivers\etc\hosts
Sorry so brief -- let me know and I can explain this more, or I think there
was a post either on the forum or in the email lists about this kind of
thing a few months ago.
So it appears to be a networking issue where the manager can't find out who
the executors are.
Let me know what you find out

Hi Anh,
I'd take a look at the log files on both the Manager and the Executors to
see if they will give you any more clues.
They are in
<Alchemi Path>\Manager\dat\
and
<Alchemi Path>\Executor\dat\
If you really want to see what's going on,
1) Stop all executors
2) Stop the manager
3) Delete the \dat\ file on both the manager and executors
4) Start the manager
5) Start the executors
6) Try to start PiCalculator
Then check the freshly-created log files and look for errors and
exceptions.
Let us know what you find.
HTH,
-Matt
