Re: [HTCondor-users] Matlab on Condor (Windows)

["Smith, Ian" <I.C.Smith@xxxxxxxxxxxxxxx>]

Hi Steve,

 

I'd like to say that I've got a solution for this but I've just tried it here and got the same result.  Our

setup is Matlab R2012a on Windows 7 64 bit with Condor 7.6.6 on the execute nodes.  Since this

used to work fine with Matlab R2011a my guess is that it's almost certainly down to a Matlab change

not a Condor one.

 

I know this sounds obvious but have you contacted MathWorks ? I've found their tech support to

be very good in the past even with obscure problems such as this. I would bet that the problem

is almost certainly down to the absence of a user profie for the temporary Condor execute

account. In the past I've had to include this in my .bat wapper file to get it to work:

 

set TMP=%CD%

set TEMP=%CD%

set USERPROFILE=%CD%

set MATLAB_PREFDIR=%CD%\My Documents\MATLAB

 

mkdir "My Documents"

mkdir "My Documents\MATLAB"

 

(%CD% will be the temp execute directory at runtime).

 

Perhaps R2012a requires more of this monkeying about

 

We try to make sure users compile their M-files here but being able to run small numbers of

them without precompiling is quite useful (esp for development/testing) - so if you come up

with any answers I would be very glad to hear them !

 

regards,

 

-ian.

We’ve previously run Matlab very successfully on our Windows setup but now we’re having problems – matlab jobs don’t complete.

 

Unfortunately, we’ve upgraded both Matlab (2012a) and Condor (7.8.2) over the summer so I’m not sure which (if either) is causing the problem.

 

A sample command we’re trying to run is:

 

matlab.exe -nodesktop -noFigureWindows -nosplash -wait -nojvm -r go

 

where “go” is the name of a .m file in the current directory.

 

The files we need are getting copied to an execute node, I can see (by using pslist) that Matlab is starting but it’s not actually executing the code in go.m (the first line of go.m creates a text file for results; that’s not being created)

 

The matlab.exe which is on the path is just some kind of loader which runs c:\matlab\R2012a\bin\win64\MATLAB.exe and that actually runs the code so I’ve tried using this command instead:

 

c:\matlab\R2012a\bin\win64\MATLAB.exe -nodesktop -noFigureWindows -nosplash -wait -nojvm -r go

 

but this doesn’t run to completion either.

 

If I just log on to a computer interactively, copy the contents of a stalled execute directory to it and try and run the submitted command then it works fine.

 

Does anyone have experience of using Matlab like this?
