Re: [Condor-users] MATLAB licenses

well most people in my lab use matlab.

so i have to use it in any case.

plus matlab is not installed on every system. but only one system from where users access it and use it over the network.

all the processing is done on the system where it is installed.

so how will condor schedule a matlab script in this case?

your scripts ?
I mean if you use some basic features of matlab, maybe octave will
suffice, and it has no licensing issues.
