Re: [Condor-users] Matlab Compiler and Condor under Windows

We've had hundreds of standalone executable Matlab jobs running
here using the same MCR from a Novell server under Win XP so
perhaps the problem is at the file server end. 
I can't see that threadlocking would be a problem when running
on separate machines ? Perhaps the number of open files is limited
on the file server.

You could just bite the bullet and download the MCR to each execute
host before running the Matlab app ( or transfer it from the 
submit host ). If the Matlab app runs for any appreciable time
this shouldn't affect the throughput too much

Incidently the compiled version doesn't check out a license - this
is the main reason we used it.
