New Features

Configuration:

Library:

N/A

Parallel Library:

Added new parallel APIs (C and Fortran: cgp_coord_multi_read_data, cgp_coord_multi_write_data, cgp_field_multi_read_data, cgp_field_multi_write_data, cgp_array_multi_write_data and cgp_array_multi_read_data) which use HDF5's multi-dataset read and write APIs. The new HDF5 feature (version 1.14.0) allows access to multiple datasets with a single I/O call. The use of these new CGNS routines can improve performance when data is accessed across several datasets from all processes since the data can be aggregated in the HDF5 or MPI-I/O library.

Bug Fixes since CGNS 4.3.0 release

Library:

  • Removed possible overflow in cgi_error, #343 #701
  • Increased maximum open file limit default
  • Added control for HDF5 tuning routine "H5Pset_elink_file_cache_size," which is useful when many external links are used, #351
  • Fixed backward compatibility issues #702:
    (a) Older CGNS files may not have enabled creation ordering in HDF5, causing issues with the number of Bases returned.
    (b) Fixed H5Fset_libver_bounds for 1.8 HDF5 when trying to read a CGNS file in 1.10 HDF5 file format and added a check which opens, for modifying, a CGNS file that uses HDF5 1.10 format. It will maintain 1.10 format capability since downgrading the file format to HDF5 1.8 requires repacking it (see h5repack from HDF5).

Fortran:

  • Removed "NULL" and "UserDefined" Fortran parameters #349

    There is a "NULL" function in the Fortran Standard so it could conflict with this definition. Therefore, CG_NULL should be used instead. Older codes need to update to use CG_NULL instead.
    Removed the "UserDefined" parameter. CG_UserDefined should be used instead. Older codes need to update to use CG_UserDefined.

Known Problems

************ FORTRAN ************

  • A gfortran bug in version 10.2 broke Fortran mapping and caused cg_goto_f
    to segfault. All other versions of gfortran are suitable.
    (ref. CGNS-246, GNU BUG 100149)

  • A bug in gfortran (all versions) causes cg_configure_f to fail,
    GNU BUG 99982. Other Fortran compilers are OK.

************ FORTRAN END ********

************ CGNSVIEW ************

  • cgnsview for OSX is not viewing properly, and cgnsview under Windows
    may fail to compile due to tcl/tk incompatibility.

************ CGNSVIEW END ********
