need to be able to determine if MPI is initialized on the server for filters that rely on MPI
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Some filters (mostly readers using MPI IO) require MPI to be initialized but don't necessarily need to be used with multiple processes. There isn't a good way to specify that so I'm adding in options to determine if MPI is initialized on the server and adding in an XML option to specify that filters require MPI to be initialized in order to be used.
