SHARCNET Cloud will be powered off and decommissioned on June 1, 2021, are you ready?



The Parallel-NetCDF library provides high-performance I/O while still maintaining file-format compatibility with Unidata’s NetCDF. While NetCDF gives scientific programmers a space-efficient and portable means for storing data, it does so in a serial manner, making it difficult to achieve high I/O performance. By making some small changes to the API specified by NetCDF, the Parallel-NetCDF Library is able to use MPI-IO and its collective operations to improve performance.
