Yep, it does flash the SPSS worksheet on the screen briefly as it runs.
Guess that's our answer then.
Actually, Condor *will* run apps that create a GUI window. You just
need to be certain that the application is batch-ready, i.e. that it
will not pop open a window and then sit and block for some
non-existent interactive user to click a button. [ you could use
Winbatch or a similar tool to help out here as well ... ].
Sometimes GUI apps are more sensitive to environment variables and
such then their non-GUI counterparts, so you may want to use
"getenv=TRUE" in your submit file.
But, if that's the case, what's the story with the "use_visible_desktop"
setting on Windows?
By default, Condor will setup a separate non-visible workstation and
desktop for GUI apps to use. If
in condor_config, then Condor will let the job pop open a window on
the default visible (console) desktop. This is almost certainly not
what you want esp for non-dedicated workstations, but can be very
handy for debugging a problem.
Something I sometimes do to debug a job running in Condor on Win32 is
a) change my executable in my submit file to be cmd.exe
b) change use_visible_desktop=true in my condor_config
and then submit. After a couple moments a command window pops up on
my screen with the same "environment" that Condor would use to run
the job, so I try running my job interactively from the prompt to see
if there are any obvious problems.
