On behalf of the parallel-netcdf developers, i present to you
parallel-netcdf version 0.9.2
. large file support (CDF-2 format) based on work by
Greg Sjaardema <gdsjaar at sandia.gov>
. More updates to the build documentation
. compiler and linker fixes for tests on IRIX
. document name changes made from serial netcdf to pnetcdf
. use a much larger buffer size when reading the header
The newest feature that 0.9.2 adds -- and the feature that could use
the most testing -- is the elimination of the 2GB barier for netcdf
datasets on 32 bit platforms. Please see the file
'README.large_files' for more information.
The short story:
. users can pass an extra flag (NC_64BIT_OFFSET) to ncmpi_create()
. datasets created with this flag will be in 'CDF-2' format. CDF-2
format uses an eight-byte value to hold a variable's offset into the
file instead of a four-byte value in the CDF-1 format
. ncmpi_open() understands both the CDF-1 and CDF-2 formats
As usual, if you run into any problems or have any questions, let the
list know.
Have fun
