Running METIS is really difficult as I am a newbie here and C language is not my programming language. And even though I am using the METIS manual, I haven't been able to run the program. I want to use the road network dataset to partition it. And maybe use the output file as the input in the Apache spark to achieve distributed processing. Anyone, could you please share the tutorial or something helpful so that I can follow the pattern or understand how to use it? PLEASE! HELP!
