How do I perform a quick test to ensure a newly-compiled executable is working before potentially wasting lots of node time?
You can submit a short job – that is, you can specify a maximum walltime with your job if you just want to see if it runs for a little while. Alternatively, perhaps you have a set of inputs for your job that that will naturally run fairly quickly, and tell you if you are getting good answers. In addition, we now have the test queue which you can use as well. See above for details on that.
