There is a web page about netCDF on the T3E at NERSC:

    http://www.nersc.gov/software/netcdf/netcdf.html

describing a version built from the netCDF 2.4.3 release, which uses the
same file format as the current netCDF 3.3.1 release.

The problems we describe with building on the T3E in the INSTALL file
that comes with netCDF 3.4a (which I've appended) indicate that it is
possible to build netCDF 3.4 on this platform, though you'll have to not
use ncx_cray.c, use the indicated flags, and precompile libsrc/putget.c
with -O2 before compiling the rest of the sources with "make".

The netCDF 3.4 alpha test version is available from
<ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.4a.tar.Z>.  We have no
access to a T3E UNICOS/mk platform locally, so it's difficult to test
our software or reproduce problems on UNICOS/mk.
