-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2009-10022 2009-09-29 13:44:46 --------------------------------------------------------------------------------
Name : netcdf Product : Fedora 11 Version : 4.0.1 Release : 1.fc11 URL : http://www.unidata.ucar.edu/software/netcdf/ Summary : Libraries for the Unidata network Common Data Form Description : NetCDF (network Common Data Form) is an interface for array-oriented data access and a freely-distributed collection of software libraries for C, Fortran, C++, and perl that provides an implementation of the interface. The NetCDF library also defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data. The NetCDF software was developed at the Unidata Program Center in Boulder, Colorado. NetCDF data is: o Self-Describing: A NetCDF file includes information about the data it contains. o Network-transparent: A NetCDF file is represented in a form that can be accessed by computers with different ways of storing integers, characters, and floating-point numbers. o Direct-access: A small subset of a large dataset may be accessed efficiently, without first reading through all the preceding data. o Appendable: Data can be appended to a NetCDF dataset along one dimension without copying the dataset or redefining its structure. The structure of a NetCDF dataset can be changed, though this sometimes causes the dataset to be copied. o Sharable: One writer and multiple readers may simultaneously access the same NetCDF file. -------------------------------------------------------------------------------- Update Information: Update 4.0.1. This release adds performance enhancements, an upgraded Fortran 90 API, ncdump handling of netCDF-4 features, bug-fixes, and portability improvements. Changes Since netcdf-4.0 Release - Added optional arguments to F90 API to nf90_open/create, nf90_create_var, and nf90_inquire_variable so that all netCDF-4 settings may be accomplished with optional arguments, instead of separate function calls. - Added control of HDF5 chunk cache to allow for user performance tuning. - Changed default chunking to better handle very large variables; made contiguous the default for fixed size data sets with no filters. - Added "-s" option to ncdump to display performance characteristics of netCDF-4 files as special virtual attributes, such as _Chunking, _DeflateLevel, _Format, and _Endianness. - Added "-t" option to ncdump to display times in human readable form as strings. Added code to interpret "calendar" attribute according to CF conventions, if present, in displaying human-readable times. - Performance refactoring of core netCDF-4/HDF5 read/write code. - Included latest netCDF classic core library code. CAUTION: The netCDF ncgen utility does not yet handle enhanced model netCDF-4 features, like groups and compound types. (Ncgen does handle netCDF-4/HDF5 files which don't make use of the new expansion of the data model). Ncgen will be able to handle such advanced features in the netCDF-4.1 release. -------------------------------------------------------------------------------- ChangeLog: * Mon Sep 28 2009 Orion Poplawski <[email protected]> - 4.0.1-1 - Update to 4.0.1 - Fix up URL and Source urls - Re-enable parallel builds - Add pkgconfig file - Add more tests to make check -------------------------------------------------------------------------------- This update can be installed with the "yum" update program. Use su -c 'yum update netcdf' at the command line. For more information, refer to "Managing Software with yum", available at http://docs.fedoraproject.org/yum/.
