What to do with Non-Portable CRAY I/O

• Convert to NetCDF:

  • Use EZCDF, it works great and is very easy to implement.
  • Makes your file MACHINE-INDEPENDENT!!!
  • See https://w3.pppl.gov/NTCC/EZcdf/ezcdf.html

• Unformatted Fortran I/O is portable but machine dependent

• If you were using the CRAY-only ZIO routines (putwa, getwa) and you need to keep the efficient direct access reads and writes, you can use the (even faster) C wrapper routines bzioC.c or bzioPOSIX.c found in https://w3.pppl.gov/~ethier/bzio
