Turing : The SIONlib library


SIONlib is a scalable parallel I/O library. This library allows reading and writing binary files for several thousand processes in one or a small number of physical files and also provides collective open and close functions for parallel access to the SIONlib files. The interfaces provided are: MPI, OpenMP, hybrid MPI/OpenMP and sequential access.

Installed versions

  • SIONlib 1.4p3rc4
  • SIONlib 1.5p1 (default version)
  • SIONlib 1.5.4


SIONlib is accessible through the module command (we advise you to read the documentation about ''module'' for further information):

  module load sionlib
