Re: [HTCondor-users] Scratch space and input subdirectories

[John M Knoeller <johnkn@xxxxxxxxxxx>]

In the $INT() macro, what ever is after the , is passed as a printf formatter string,   so you can do

 

    $INT(Process,_%d_)

 

To get

   _1_

 

Etc.

 

So we preserve the leading space in this case because you might want to have it,  and it “probably” won’t matter

On the output side.  The exception, of course is when you are token pasting as you are there.

 

On the other hand, because we allow for arbitrary printf formats, you could also do this.

 

remote_initialdir = $INT(Process, case=%d)

I tried that as well and it didn't work, so I thought the problem was that the directory had to exist before the PreCmd ran, but I didn't examine the hold message closely enough:

  98.0   pelletm         2/17 14:25 Error from slot2@condor1: Failed to execute '/var/lib/condor/execute/dir_600967/condor_exec.exe' with arguments 600: Cannot access initial working directory "case= 1" (errno=2: 'No such file or directory')

Note the space. I had the INT directive specified with a space after the comma, like so:

CASENUM = $(Process) + 1
CASEDIR = case=$INT(CASENUM, %d)
remote_initialdir = $(CASEDIR)

Spaces after commas and around plus signs make me happier, I'm funny that way. But that gave a string of "case= 1" instead of "case=1" as the hold message was trying to explain. Once I changed it to $INT(CASENUM,%d) it works, and the ssh to the job places me in the working directory of the executable, $TMPDIR/case=1.

Thanks! It wouldn't be a bad idea to have a note of these little caveats in the manual - for instance $$([$(Process)+1]) can't have spaces either.
