General Purpose Computers

  The telescope operators will use screens displayed on multiple monitors to control and monitor the telescope. These monitors are standard 21 inch Sun monitors, with a resolution of 1152 x 900 pixels. The operator control computers are Sun UltraSPARC workstations, with each computer driving either two or three screens. The number of screens is dependent on the Telescope Operations group's designs, which are still being finalized.

Data will be collected and written to the RAID via any one of three computers. The spectrometer and spectral processor each contains its own data collection machine, and an additional data collection computer is used to aggregate the data from the rest of the telescope systems.

A fourth computer will be connected to the RAID for read-only access to the data via the Network File System (NFS). This workstation will be located in the equipment room and will serve as an engineering workstation, to be used mainly for troubleshooting and working with the equipment in the equipment room.

The Precision Pointing System will use another workstation as a compute server, and for coordinating the tasks of the Laser Metrology system and the Active Surface system. This computer is located on the telescope alidade, approximately 2.5 km from the control room.
