Synthetic Seismograms, Graphic Software and Computer Facilities.
Abstract
A SUN-1/100U graphic workstation, which was installed in the Seismology Computing Lab. at Lamont-Doherty, has become the centerpiece of a digital waveform processing and analysis facility. A local area network (LAN) comprising Ethernet/TCP-IP protocols connects the SUN-1 with the Observatory's pre-existing VAX 11/780 and PDP 11/70 installations. The operating systems on the VAX (VMS) and the PDP (Unix bsd 2.9) were updated and modified to provide support for the full set of Ethernet utilities. The Ethernet LAN is undergoing start-up testing and soon will be fully operational. While the SUN-1 offers only rudimentary computational power, its state-of-the-art graphic capabilities have enabled us to develop a 'quick-look' digital data-handling facility. Once the network is fully operational, the resources of the Observatory's other computer laboratories will become available to the SUN-1. The VAX will be used as the network file-server, peripheral handler, and computational node, while the SUN will be used for the graphic analysis of waveforms and digital images. Preliminary experiments with the network suggest that powerful graphic workstations integrated vertically with file-servers, computational nodes, and supercomputer communication capability provide a flexible, powerful, and productive computational environment for research in seismology and tectonophysics. Keywords: Seismic data processing; Geological observatories.
