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.
