Just wondering if being able to pause a phenix run would be something useful. Currently, it appears one can only abort. Currently doing refinement of a large structure, and doing several simultaneous runs with different options is slowing down the computer too much. Individual runs take about 72 hrs, so o/n is not an option (o/weekend will be...) (or is it possible and I have missed it?) if the FPLC can do it, why not phenix? Seriously, I don't know how easy or difficult it would be to implement, or if paused runs would still take up too many resources, but it seems like something that might be useful - i.e. set several long runs running, and temporarily interrupt them for other jobs on the same computer (like watching youtube movies, as some people seem to think I do all day...)
