Concurrent introduces MAX/OS -- Industry's first POSIX compliant real-time operating system based on UNIX System V4.2 for multiprocessing systems.OCEANPORT, N.J.--(BUSINESS WIRE)--Dec. 1, 1994--Concurrent Computer Corp. today announced MAX/OS(TM) Version 1.1 real-time implementation of Novell UNIX Systems Group's UNIX UNIX Operating system for digital computers, developed by Ken Thompson of Bell Laboratories in 1969. It was initially designed for a single user (the name was a pun on the earlier operating system Multics). (R) System V Release 4.2 MP (SVR4.2MP). This release continues Concurrent's pioneering tradition as the industry leader in high-performance real-time operating systems. The MAX/OS real time UNIX System will be available later this month and is included as part of Concurrent's MAXION(TM) multiprocessor system. Earlier this year, Concurrent and Novell's UNIX System Group launched a joint effort to develop the specific real-time extensions to UNIX SVR4.2MP that would become the universal real-time standards endorsed within the POSIX framework. MAX/OS conforms to all major open systems standards, including POSIX 1003.1, POSIX 1003.2 X/Open subset, and X/Open XPG4 and UNIX System V Unix System V - System V standards including the System V Interface Definition, STREAMS, System V device driver interface (DDI ddI and ddC: see AZT. ), and System V device kernel interface (DKI). In addition, MAX/OS implements extensions such as POSIX 1003.1, formerly 1003.4, real-time extensions and POSIX 1003.1c, Draft 8, formerly POSIX 1003.4a, multiprocessing threads extensions. Del Kunert, Concurrent's director of Open Systems Product Marketing, said: "Concurrent believes that MAX/OS will set the standard for robust, real-time performance and adherence to open systems standards. MAX/OS 1.1 real-time UNIX operating system Noun 1. UNIX operating system - trademark for a powerful operating system UNIX, UNIX system operating system, OS - (computer science) software that controls the execution of computer programs and may provide various services implements Concurrent's UltraSMART(TM) Scalable Multiprocessor Architecture for Real-Time. Customers will find that the MAX/OS real-time UNIX operating system running on our MAXION multiprocessor system provides exceptional scalability and extensibility. This is a truly efficient, powerful open system and commercial-off-the-shelf (COTS) solution for a wide variety of commercial, technical and defense-related applications." An Operating System Ideal for Third-Party Developers One of the primary benefits of the MAX/OS operating system is that it is compliant with the MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. ABI Abi (ā`bī) [short for Abijah], in the Bible, King Hezekiah's mother. (Application Binary Interface) A specification for a specific hardware platform combined with the operating system. (application binary interface See ABI. (programming) Application Binary Interface - (ABI) The interface by which an application program gains access to operating system and other services. It should be possible to run the same compiled binary applications on any system with the right ABI. ), as defined by Version 1.1.1 of the MIPS ABI Conformance Guide. The MIPS ABI is based on UNIX System V Release 4 and sets a single software standard for all MIPS Technologies reduced instruction set computer (processor) Reduced Instruction Set Computer - (RISC) A processor whose design is based on the rapid execution of a sequence of simple instructions rather than on the provision of a large variety of complex instructions (as in a Complex Instruction Set Computer). (RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. )-based systems. The MIPS ABI allows a single version of software to run unchanged across all MIPS ABI-compliant systems. The mipsABI enables the availability of third-party shrink-wrapped software applications for the MAXION multiprocessor system similar to the wide variety of software available for PCs. The popularity of the MIPS Technologies RISC microprocessor with the largest installed base of multiprocessing systems ensures the market availability of a wide variety of application software.
