Re: [Condor-users] Location of Execution files

["Stefan Tomasiewicz" <cs05stt@xxxxxxxxxxxx>]

Great, I see, so it's the process ID, I will check out _Condor_Exec_Dir and the Search through 7.2/3 releases for the new config variable. 
 
What I am trying to do is change my code, previously I had a Microsoft Excel spreadsheet file on each local directory, however I will be moving to a new and bigger set up where I won't be able to place the file on each PC. So i have to farm out the Excel file, along with the program I will be executing. I'm looking to change my code so that it will open up the Excel file within the temp execution directory. If there is a simple way to do this I would appreciate any guidance. 
 
Regards,
Stefan

It is always the process ID of the condor_starter process that gets
spawned to run the job. Condor places the path in your environment when
the job's Cmd is executed. I'm not at my pool right now but IIRC it's
_CONDOR_EXEC_DIR. Something close to that. So your job can read that env
var on startup.

As for controlling it: I seem to recall reading a snippet in a release
note for 7.2 or 7.3 about a new config variable that'll let you set a
per-slot execution directory. Or maybe that was just a wonderful dream I
had and I'm mistaken. If there isn't a config variable to do this
consider it my request. Sure would be nice to split execute directories
between multiple disks in my machines to reduce some I/O contention.

What are you trying to do? Edit a text file that contains C++ code and
then compile it as part of a job?
