Hi,

I use the same wrapper but from an other link 
(http://egee-uig.web.cern.ch/egee-uig/production_pages/MPIJobs.html).
Your wrapper should work. I have run the Hello world MPI code to display 
the arguments defined by
'export I2G_MPI_APPLICATION_ARGS="./ 10 10"' and it works.

Following is an example of a real MPI job :
...
export MY_INPUT=$3
...
export I2G_MPI_APPLICATION_ARGS=${MY_INPUT}

I think that the problem must come from a little shell syntax in the 
user's wrapper.
