That limit was well below the size of any of the larger target sets we deal with, so using cachefs as a solution to data staging led to thrashing, particularly when we started splitting up the targets to better parallelize our searches. I'm curious to know if this is still the case. Of course, a truly brilliant resource scheduler would take into account the contents of the file cache when deciding where to run a particular job... -Chris Dwan University of Minnesota
