Concurrent Computer Corporation
Concurrent Computer Corporation was an American computer company, in existence from 1985 to 2017, that made real-time computing and parallel processing systems. Its products powered a variety of applications including process control, simulators, data acquisition, and video-on-demand. It was based in Monmouth County, New Jersey, initially, and then later in Fort Lauderdale, Florida and Duluth, Georgia.
The company was created in November 1985 when the computing division of Perkin-Elmer, the Data Systems Group, was spun off as a separate company. The computing group, which had started out as the company Interdata before Perkin-Elmer acquired it in 1974, had been profitable with sales of $259 million, but had tended to have reduced visibility within the computing industry due to being owned by a diversified parent. At first, the new company was a wholly owned subsidiary of Perkin-Elmer, but with the intentions of putting a minority ownership in the company up for a public stock offering. This was subsequently done, with Perkin-Elmer retaining an 82 percent stake in Concurrent; the remainder went on sale in February 1986 and opened at $20 per share. The stock traded on the NASDAQ exchange.
James K. Sims, who had been general manager of the computer unit within Perkin-Elmer, became president and CEO of the new company. It had a large presence in Monmouth County, New Jersey, with some 1,700 staff making it one of the county's largest private employers. Its plant in Oceanport had 800 employees alone.
By 1987, Concurrent had nine separate offices in various locations in Monmouth County. Corporate headquarters had initially been Holmdel, but during 1987 moved to Tinton Falls.
The initial focus of Concurrent Computer Corporation was in the 32-bit superminicomputer market, with an offering that emphasized parallel processing. Their oldest product was the Series 3200, which came from its Interdata heritage and was based around a proprietary discrete component processor that supported 8 sets of registers and was built using the AMD Am2900 bit-slice chip set. The 3200 Series ran the OS/32 real-time operating system. Two newer products were the Series 5000, based on a Motorola 68020 processor, and the Series 6000, based on a Motorola 68030. In these products, the company focused on the market for high-end, rapid-response applications. Aircraft simulators were an especially important market.
Many of Concurrent's customers were in the defense and aerospace industry. Accordingly, Concurrent offered a line of compilers for the Ada programming language that at the time was often mandated for such applications. The company's C3Ada product came out in 1987; it ran on OS/32 and was among the early wave of commercial products to get past the strenuous Ada Compiler Validation Capability (ACVC) validation suite. The company's languages group investigated the challenges of implementing Ada, with its built-in tasking feature, on a real-time system with multiple processors, and in how best the requirements of real-time systems could be expressed in the language.
The Fortran programming language was perhaps the most popular choice for applications on the Concurrent platform. Optimizing Fortran for a shared-memory multiprocessor presented special issues regarding do loops and cache thrashing, a subject that the compiler staff at Concurrent studied extensively.
By 1988, there were some 2,800 employees in the company overall, and at its peak, the Oceanport manufacturing facility would have nearly 1,000 people working at it. Revenue for 1987 was $247 million.
