MPP_IO Performance

• NetCDF and binary I/O was considered:
  • Can be controlled via the “form” argument of MPP_OPEN:
    • MPP_NETCDF
    • MPP_NATIVE
• Testcases for NetCDF I/O:
  • Multiple processes write to multiple files (mm)
  • One process writes to a single file after data gathering (ss)
  • Multiple processes read from one file (ms)
• Testcases for binary I/O
  • Only case mm and ss were considered, access is sequential
