Description
PnetCDF is a high-performance parallel I/O library for accessing Unidata's NetCDF, files in classic formats, specifically the formats of CDF-1, 2, and 5. CDF-1 is the default NetCDF classic format. CDF-2 is an extended format created through using flag NC_64BIT_OFFSET to support 64-bit file offsets. The CDF-5 file format, an extension of CDF-2 and created through using flag NC_64BIT_DATA, supports unsigned data types and uses 64-bit integers to allow users to define large dimensions, attributes, and variables (> 2B array elements).
In addition to the conventional netCDF read and write APIs, PnetCDF provides a new set of nonblocking APIs. Nonblocking APIs allow users to post multiple read and write requests first, and let PnetCDF to aggregate them into a large request, hence to achieve a better performance.
