[HTCondor-users] _CONDOR_SCRATCH_DIR in submit file?

[Dimitri Maziuk <dmaziuk@xxxxxxxxxxxxx>]

Hi all,

can I use _CONDOR_SCRATCH_DIR is a submit file?

I could swear I had it working without a wrapper script at one point but
now I can't remember how (if) I did it.

This is a (compiled) matlab job that hits the usual
"Could not access the MATLAB Runtime component cache."

With the submit file specifying:
environment = "MCR_CACHE_VERBOSE=1
MCR_CACHE_ROOT=$ENV(_CONDOR_SCRATCH_DIR) ...

The output is

> Creating MATLAB Runtime Cache at location: UNDEFINED/.mcrCache9.0.1
> ...
> File open failed for /var/lib/condor/execute/dir_1400101/UNDEFINED/.mcrCache9.0.1/.mcr_cache_index
> ...
> Checking whether index file /var/lib/condor/execute/dir_1400101/UNDEFINED/.mcrCache9.0.1/.mcr_cache_index needs to be written...
> Write is needed.
> Writing cache index file: /var/lib/condor/execute/dir_1400101/UNDEFINED/.mcrCache9.0.1/.mcr_cache_index
> ...
> Unable to start MATLAB. Relative path for preferences directory ('UNDEFINED/.mcrCache9.0.1/main_F0/.matlab') is not supported

Two questions: is it supposed to be "UNDEFINED" and how can I get the
absolute path? -- it seems matlab writes to UNDEFINED just fine and only
cares about relative path.

TIA
