John: I've built netcdf on the T3E, but only the "C" interface. /t3ehome3/ncar/netcdf-3.3beta It appears that the fortran to C calling conventions have changed. We are now using a package called "cfortran" from ftp:zebra.desy.de That package doesn't appear to support the t3e architecture yet. Perhaps you could have one of your experts pull this over and look at it. (It comes with tests.) I also rebuilt on the T90. There are some problems with edge cases in the new fortran interface, but these may be more problems with the test suite than with the library code. The old-style fortran interface (what you undoubtly have in use) passes its test. -glenn
