Fedora 11 Update: netcdf-4.0.1-1.fc11



--------------------------------------------------------------------------------
Fedora Update Notification
FEDORA-2009-10022

--------------------------------------------------------------------------------

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.
