the ART is the executable that runs on the agent to check if the agent
is deemed "usable" for the task at hand (tutorial coming on
MacResearch!). This means Podcast Producer is using Scoreboard to
select which agents are worthy of using. It might be documented by
Podcast producer (e.g. agent specs), or it might be something you need
to figure out from the Podcast Producer developers.
One thing you could try is to "catch" the ART executable by killing
xgridagentd on the agent when it receives the ART executable. Xgrid
will hopefully not have time to clean the /var/xgrid/agent folders,
and if the executable is a script, you can even see what kind of code
is used to select appropriate agents. Of course, you cannot change
that code, but maybe you can do something to the agent to make it
acceptable by Podcast Producer.

Please bear with me, I'm a novice to xgrid - I'm learning about it
as part
of my project to implement Podcast Producer.
I have PcP working (and by extension xGrid) with a controller and
agent on
the Leopard server machine. Now I'm experimenting with configuring
Mac
clients to serve as agents to help with some of the load of
processing these
jobs. I've configured 1 Tiger client and 1 Leopard client as an
xgrid agent
using the GUI in Sharing of System Preferences. Once I have that
done, I
checked Xgrid admin on the Leopard server and saw that the clients
were
listed under agents as available. But, when I run some jobs, those
agents
aren't used. I was skimming through the logs and found a reference
to "art
returned score of "0" ..." Based on the research I've done so far, I
understand that this refers to the scoreboard in xgrid on Leopard and
defines whether a job is sent to a client (whether the score is 1 or
0?) So
my question is what do I need to edit on the client or the server to
get it
to return a positive score an therefore (I presume) use said agent
for a
job?
Any help, suggestions or comments would be greatly appreciated!
