**The PIO team is pleased to release version 2.5.8 of the PIO library. This release includes bug fixes, and more tests. Get the latest release from: https://github.com/NCAR/ParallelIO/releases/download/pio2_5_5/pio-2.5.8.tar.gz

We have added a PIOc_InitDecomp_ReadOnly for simultaneous reading and filling halo regions. Decompositions created using this call can only be used for read operations.

See https://ncar.github.io/ParallelIO/ for documentation.

What is PIO?

The Parallel IO libraries (PIO) are high-level parallel I/O C and Fortran libraries for applications that need to do netCDF I/O from large numbers of processors on a HPC system.

PIO provides a netCDF-like API, and allows users to designate some subset of processors to perform IO. Computational code calls netCDF-like functions to read and write data, and PIO uses the IO processors to perform all necessary IO.

PIO also supports the creation of multiple computation components, each containing many processors, and one shared set of IO processors. The computational components can perform write operation asynchronously, and the IO processors will take care of all storage interaction.

See the PIO web site for more information: https://ncar.github.io/ParallelIO/.

New This Release

• Subset rearranger method improvements for read
• Added fortran support for pio_write_nc_dof and pio_read_nc_dof
• Add a program, dofcopy, to copy old style dof text files to netcdf format
• PIO_BUFFER_SIZE_LIMIT renamed PIO_PNETCDF_BUFFER_SIZE_LIMIT
• Add return code to fortran function pio_deletefile
• CMake build no longer includes fortran unless PIO_ENABLE_FORTRAN is ON
• Bug fix in handling PIO_BYTE data type

Required Libraries

We recommend always using the latest releases of netCDF and pnetcdf.

This release requires:

• netcdf-4.6.1 or newer. 4.7.3 or newer is required if --enable-netcdf-integration is used.
• pnetcdf-1.9.0 or newer (unless PIO is built without pnetcdf support).
• If netCDF is built with HDF5 support, then HDF5-1.10.4 or newer is required.

The PIO team is pleased to release version 2.5.4 of the PIO library. This release includes bug fixes, and more tests. Get the latest release from: https://github.com/NCAR/ParallelIO/releases/download/pio2_5_4/pio-2.5.4.tar.gz

New This Release

• bug fix in the pio_put_vars_tc for pnetcdf (see #1861).
• a fix to the TryNetCDF_DAP.c to add DAP2 and DAP4 (see #1863).

Required Libraries

We recommend always using the latest releases of netCDF and pnetcdf.

This release requires:

• netcdf-4.6.1 or newer. 4.7.3 or newer is required if --enable-netcdf-integration is used.
• pnetcdf-1.9.0 or newer (unless PIO is built without pnetcdf support).
• If netCDF is built with HDF5 support, then HDF5-1.10.4 or newer is required. Previous versions of HDF5 have a bug in parallel collective I/O which is triggered by a PIO unit test.
