Datacomputer and Sip Operations
Abstract
This report describes our work during the first quarter of 1977 in providing very large on-line storage and retrieval services over the Arpanet to support seismic data activity and general use. These services are provided via the Datacomputer, a system designed to allow convenient and timely access by multiple remote users over a communications network to a large on-line database. The Datacomputer runs, under a modified TENEX operating system, on a DEC PDP-10 computer. This configuration has been augmented with the first public installation of the Ampex Tera-Bit Memory (TBM) System to supply the large on- line storage capacity required. The seismic application, the largest user of the Datacomputer, sends much of its data in real time. This real time data stream is fielded by a special dedicated processor, the Seismic Input Processor or SIP. The SIP accepts and buffers the real time data, reformats it and periodically forwards it to the Datacomputer. In order to maximize the utility of the above services to the seismic and Arpanet communities, CCA assests users in such ways as providing simple general user programs and advising users on file and retrieval design, as well as providing documentation. Activities in the area are discussed in Section 5 below.
