Hi, Akio

Sorry I didn't get to this before the weekend. I've prepared the job files 
for this, and I see that it's almost 18k files with over 150M events. I've 
made some tests and calculations to find that this test production, unless I 
significantly interrupt the ongoing 3 physics productions, will take 2-4 
weeks to process. So....it isn't really all that small. Output would be ~25 
TB of MuDsts.

Any chance you are willing to scale this back a bit? e.g. a quarter of the 
files or runs? Or do you really need this much?

Thanks,
-Gene
