COMPUTING FACILITIES AND ON BOARD DATA PROCESSING

On the on ship's existing Ethernet coaxial backbone we established a network of computers for swath bathymetry and general purpose data processing, as shown by Fig. 22. Among them, PC's running Linux and Windows OS, and two SUN ULTRA 1 workstations running Solaris 2.5 and 2.7 OS. The SUN WS were devoted to multibeam data processing, whilst the LINUX WS were used for NFS disk and printer spooling services. In addition to this, ELETTRA's Sparc Station 20 workstation, running Solaris 2.5 OS was also used. One HP Mod. 750 A0 color ink-jet plotter was used for charting.

During the 60 days cruise, we can report just a few stops of some machines, that recovered smoothly after the reboot or file system check.
