PnetCDF (Parallel netCDF)
Parallel netCDF (PnetCDF) is a library providing high-performance I/O while still maintaining file-format compatibility with Unidata's NetCDF.
NetCDF gives scientific programmers a space-efficient and portable means for storing data. However, it does so in a serial manner, making it difficult to achieve high I/O performance. By making some small changes to the NetCDF APIs, PnetCDF can use MPI-IO to achieve high-performance parallel I/O.
