Pete,

The Sparc computers will run different executables than the PC based
Solaris operating system.

Your Ultra 2 can serve data to the PC's for shared files, but you
will need to have a separate set of executables for LDM, Gempak, McIDAS etc.
The Gempak distribution allows for sharing of common tables etc,
and separate binaries for different operating systems using the $NA_OS
environmental variable (set when you source the Gemenviron file).
For the Sparc, the executables are in $NAWIPS/bin/sol, for the X86
machines they would be under $NAWIPS/bin/x86. If your PC's mount the data
and software from the server using NFS, then Gempak can share all the
other data bases under the $NAWIPS tree- and your path would set the
appropriate executable directory when you source Gemenviron.
