Subject: Re: [MTT devel] Best way to run ftb_database_server and ftb_agent

Are you executing an MPI Get section?

I believe that the mpi_details section is filled in via the MPI Get phase and then propagated down through all the other phases (i.e., each of the other phases looks allll the way back to their corresponding mpi get phase to find the mpi_details value).
