[Francis E Reyes]

Any possibility to support art scripts in PyXG?

Francis,

What is an art script?

Agent reporting tool....

It's a preflight script that the controller sends out to agents before
a task is run .. A number of criteria (memory, cpu's,
gpu's,etc,whatever you want) are each assigned a numerical 'score' and
all scores are multiplied together for a given machine. These are sent
back to the controller, which ranks the scores, and assigns tasks
based on the score list.

Presumably this system can rank agents based on whatever criteria you
want.. (i.e. don't run this job on a PPC/Intel or where load/mem/cpu
is <> some value).

I *think* the preflight scripts are assigned just before a task is
assigned allowing the controller to assess cpu load values of each
agent in 'realtime'. (for those agents who accept tasks even when not
idle).

Ahh, OK.

I was not familiar with this, but it should not be too difficult to
add this. I don't have time to work on this myself, but feel free to
have a go yourself. The pyxg code is up on github:

https://github.com/pyxg/pyxg

So feel free to fork this and submit a pull request.

It would be nice to have this capability for sure. Beat Rupp (the
other pyxg maintainer) may also be interested in this and have more
time to help in the development.

Cheers,

Indeed, this would be a nice feature. To prevent PPC machines from
accepting jobs, I just removed them from the grid, which was easy in
my case with a limited number of computers. However, I have no time
for development currently. I'm happy to answer questions along the way
though.

Cheers,
Beat
