This report evaluates the role of the pluribus, a multiprocessor multibus system, in its role as the communications control processor CCP at the Seismic Data Analysis Center SDAC over the 26 months from its installation in April 1977 through May 1979. In capacity the six processor Pluribus at the SDAC provides a bandwidth somewhat greater than 750,000 instructions per second, equivalent to three processors working full time. For the 16.8 KBsec input and 28.2 KBsec output data streams at SDAC operating in May 1979 this capacity is in excess of double the bandwidth required. The hardware reliability of the Pluribus lives up to its billing. However, the system suffered over 8 downtime, primarily due to software problems. The CCP is in an RD environment at SDAC which required revisions of the CCP inputs and functions over the 26 months of operation studied.
