Re: [Gems-users] FILE_SPECIFIED Topology

["Niket Agarwal (niketa@xxxxxxxxxxxxx)" <niketa@xxxxxxxxxxxxx>]

Yes, look at any of the files present in simple/Network_files. You will get an idea about the requirements of the file. You need to connect all external nodes (L1 and Directories in case of an SMP protocol) to internal nodes. The GarnetFileMaker.py is primarily to assist you in connecting the internal nodes in a mesh like topology. 

Cheers, 
Niket
