Fascinatingly, the problem is not in starting all the jobs in parallel (that
was a script taking <30minutes to write). It's gathering and looking at the
I suppose the real problem is in the user interface. The code I'm running
has a long punched card heritage (yesirree, the input file is called a "NEC
deck", and the output file has carriage control characters in column 1), so
there's a wide variety of "front ends" to it to make the deck prep and
output viewing easier.
It's these prep and output viewer programs that need to be "cluster aware".
