Workplace OS (original) (raw)

dbo:abstract

IBM Workplace OS（IBMワークプレイスOS）は、IBMが1990年代に計画・開発していたマイクロカーネルベースのオペレーティングシステムである。 (ja)
Workplace OS is IBM's ultimate operating system prototype of the 1990s. It is the product of an exploratory research program in 1991 which yielded a design called the Grand Unifying Theory of Systems (GUTS), proposing to unify the world's systems as generalized personalities cohabitating concurrently upon a universally sophisticated platform of object-oriented frameworks upon one microkernel. Developed in collaboration with Taligent and its Pink operating system imported from Apple via the AIM alliance, the ambitious Workplace OS was intended to improve software portability and maintenance costs by aggressively recruiting all operating system vendors to convert their products into Workplace OS personalities. In 1995, IBM reported that "Nearly 20 corporations, universities, and research institutes worldwide have licensed the microkernel, laying the foundation for a completely open microkernel standard." At the core of IBM's new unified strategic direction for the entire company, the project was intended also as a bellwether toward PowerPC hardware platforms, to compete with the Wintel duopoly. With protracted development spanning four years and $2 billion (or 0.6% of IBM's revenue for that period), the project suffered development hell characterized by workplace politics, feature creep, and the second-system effect. Many idealistic key assumptions made by IBM architects about software complexity and system performance were never tested until far too late in development, and found to be infeasible. In January 1996, the first and only commercial preview was billed under the OS/2 family with the name "OS/2 Warp Connect (PowerPC Edition)" for limited special order by select IBM customers, as a crippled product. The entire Workplace OS platform was discontinued in March due to very low market demand, including that for enterprise PowerPC hardware. A University of California case study described the Workplace OS project as "one of the most significant operating systems software investments of all time" and "one of the largest operating system failures in modern times".

We have not closed discussion on [Mac OS support]. We're talking with Apple about including the Macintosh OS as one of the personalities in the microkernel. (en)
There is no good way to factor multiple existing systems into a set of functional servers without making them excessively large and complex. In addition, the message-passing nature of the microkernel turns out to be a poor match for the characteristics of modern processors, causing performance problems. Finally, the use of fine-grained objects complicated the design and further reduced the performance of the system. Based on this experience, I believe that more modest, more targeted operating systems consume fewer resources, offer better performance and can provide the desired semantics with fewer compromises. (en)
GUTS defined [theoretical] operating system components similar to Taligent's [already existing] operating environment, only the components [in GUTS] were defined procedurally ... From the concept of shared services and Taligent's concept of object-oriented system frameworks, an object model evolved that represents the new, faster, and more reliable way of building operating systems. What's more, because procedural and object-oriented components can coexist in a microkernel-based operating system, the evolution to a completely object-oriented world could be staged. (en)
