[IPython-dev] Parallel magic and exception

[thwiouz]

Hi guys,

I'm currently testing the parallel mode of IPython for a project. My problem
is that I need to run a lot of 
simulations (for loop) for a Monte Carlo program with some code I wrote.
Because I had no idea about the 
computation cost of my program, I totally handled it into a notebook. Thus
everything is self contained 
(definition of new classes, functions and so on).
In my last cell I do my loop and then I get the result I want.

In order to parallelize my Notebook without modifying it a lot, I started to
read the doc and use the %autopx 
magic which works well. In order to do so, I first create a client, then a
view that I put into synchronous mode 
and then I execute my whole notebook.

At the end, I use the view dict to get my variables back to get the results
of the computations and everything 
should work well. Everything looks like okay, but I have got a f***ing error
in my code, well this is a 
RuntimeWarning (that I filtered to an 'error') for some of my engines.
Obviously, I do not handle the error 
right because the  engines that encountered the error stop without getting
any stack of what happened.

I saw something about CompositeError, but how do I manage it into a loop
into the engine side?

Thanks a lot,
