The CDF-5 file format, an extension of CDF-2, 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 also provides a new set of nonblocking APIs. Nonblocking APIs allow users to post multiple read and write requests first, and later let PnetCDF to aggregate the requests into a large MPI-IO request, hence to achieve a better performance. See nonblocking I/O for further description and example programs. "
