I have not known how to redirect a command from a file to cplex instead of typing it; so I can not submit this job to the grid.

And there is a way to obtain a file name from the command line of the qsub and transfer this file name to cplex as its input instead of fixing it in the script?

Thanks for your explanation.

Is it possible to run a shell script (that then calls CPLEX) through qsub?

For example: "qsub bash -- runcplex.sh mymodel.lp" with 'runcplex.sh' being the following:

#!/bin/bash
 
cplex <<EOF
set log $1.log
read $1
opt
disp sol qual
write $1.sol
EOF

We never added the option to directly provide a model file name as parameter to the CPLEX interactive, because this piping of input commands always worked for every situation that we encountered so far. If this does not work for qsub, we may change this and add support for command line parameters.
