What ever happened to Tandem and NonStop OS 1979

What ever happened to Tandem and NonStop OS 1984
It is "on behalf of the user". Only scheduling, context setup and interrupts&exceptions really need ring0 priviliges. The rest can be...
What ever happened to Tandem and NonStop OS 1981
I realized that. I'll try. Since I didn't do any of the coding, anything I say will be second-hand. For whom? The monitor itself or the user it's currently servicing? There is big...
What ever happened to Tandem and NonStop OS 1983
Which, IME, dooms it because there is no long range plan for extending the feature included in the design. However, this is how we used to...

some old news ...

What ever happened to Tandem and NonStop OS 1980
Well, tend to, but are by no means guaranteed to ... I've used multiprocessing (as in, 2 to 8-way SMP RISC UNIX) systems that weren't at all "smooth". And that's with both...

International Business Week, 9-26-88

* In a few months Intel will introduce its 80486 microprocessor - mainframe on a chip - 1 million transistors - equal to low-end IBM 3090 * New age of personal mainframes * Microprocessors will replace central processing units in mainframes * Today Intel directly sells 20% of world's microprocessors - 70% of all PCs use Intel technology - 386 chip could be in up to half "IBM-type" PCs next year * Intel's business is booming - first half 1988 earnings up 211% to $224 million - on revenue up 64% to $1.4 billion * The 486 chip should sell initially in 1989 for about $1,500 - expect 486 based PC in 1990 for about $20,000 - such a PC should be able to run dozens of simultaneous large apps - will greatly concentrate power into the executive suite * Competing RISC designs promise ten-fold speed-ups - Sun's Sparc chip is licensed by AT&T, Unisys and Britain's ICL - MIPS Computer Systems RISC chip is licensed to Tandem Computers - Sun and MIPS RISC chips will be produced and marketed by TI, LSI Logic, Fujitsu, Cypress Semiconductors and others - Motorola and Intel have introduced their own RISC chips * Superfast chips of any design will open new opportunities in application areas - Intel safe in office applications thanks to $12 billion worth of IBM-type PC programs but other areas are more open * Mainframes could be built using these microprocessors - standardized chips encourage mainframe cloning - startups spared the up front costs of developing CPU and S-W - Zenith Data Systems and Compaq Computer are planning to move into minicomputers and mainframes using Intel's chips - Intel already packages its chips into systems ranging from printed-circuit boards to finished PCs - Intel is in a 50-50 joint venture with Siemens to build a fault-tolerant mainframe called Biin (buy-in?) - Biin is due out this October - Intel's systems business is 27% of total revenue this year and is expected to be 33% in 1990 * Intel is improving its manufacturing capability - closed 8 outdated plants - spending $450 million this year on leading-edge equipment and new plants - let 25% of its workforce go, 6,000 workers and managers - revenue per employee doubled last year to $100,000 * Parallel systems promise even better price-performance - Intel has sold nearly 150 hypercubes containing 8 or more MPUs - Hypercube can outperform a Cray at certain tasks - Sequent Computer Systems of Beaverton, Oregon builds parallel systems of mainframe performance that sells for one tenth the price - Sequent's 120 MIP Symmetry system supports hundreds of simultaneous users, putting it in the range of IBM's biggest 3090 - But Sequest's Symmetry costs $5,000 per MIP and IBM costs $120,000 - Intels biggest parallel system delivers 512 MIPs with 128 MPUs, more than any commercial maimframe by 40% (100 megaflops vrs 70 megaflops) - Cost per megaflop: Intel=$10,000; Cray=$100,000 - Others are selling parallel systems built from Motorola, Intel, Inmos or National Semiconductor MPUs - Boston's Stratus Computer, based on Motorola MPUs, has installed 1,444 systems at places such as Gillette, Visa International, and the National buttociation of Securities Dealers - Stratus' sales were $184 million in 1987 and have been compounding at roughly 50% a year
