Re: [HTCondor-users] Condor + MatLab + Windows + UNC

What version of MatLab are you running?
What version of HTCondor?
What does the submit file look like (i.e., how are you starting Matlab):

Hello all and thanks for reading / giving some input:

We have set up a simple lab with one node acting both as master and
execute on Win 7 (no domain).
Same unit has MatLab.

There is a NAS device on the network accessed with UNC paths.

We've set up Condor to launch MatLab with user impersonation and the
condor_submit description file uses run_as_owner = true.
When invoking Matlab through Condor and watching Task Manager we can
see MatLab launching as the submitting user.

Here is the anomaly:

When launching MatLab from the standard desktop by icon, within
MatLab the Path entries to the UNC share are there and no warning is
posted on startup.
When launching MatLab from a CMD windows with MatLab -r mFile, MatLab
launches, executes mFile, and again there are no warnings in respect
to Path entries.

When we launch through Condor, we are presented with a warning about
all the UNC Path entries:

Warning: Directory access failure: file://diskstation/Matlab [1]
Warning: Directory access failure: file://diskstation/Matlab/Data [2]
.... [edited for brevity]

This information is being trapped launching MatLab with the -logfile
switch within Condor.
No errors are reported within Condor and the instantiated MatLab
(under the user's account) simply hangs until we kill it through Task

There are no access denied logs on the UNC device, and the shares are
globally open - read / write / browse.

Any thoughts on how to hunt this problem down is appreciated.
