Overview

Singularity is an experimental operating system developed by Microsoft Research between July 9, 2003, and February 7, 2015. It was designed as a high dependability OS in which the kernel, device drivers, and application software were all written in managed code. Internal security uses type safety instead of hardware memory protection. Operation The lowest-level x86 interrupt dispatch code is written in assembly language and C. Once this code has done its job, it invokes the kernel, which runtime system and garbage collector are written in Sing# (an extended version of Spec#, itself an extension of C#) and runs in unprotected mode. The hardware abstraction layer is written in C++ and runs in protected mode. There is also some C code to handle debugging. The computer's basic input/output system (BIOS) is invoked during the 16-bit real mode bootstrap stage; once in 32-bit mode, Singularity never invokes the BIOS again, but invokes device drivers written in Sing#. During installation, Common Intermediate Language (CIL) opcodes are compiled into x86 opcodes using the Bartok compiler. Security design Singularity is a microkernel operating system. Unlike most historic microkernels, its components execute in the same address space (process), which contains software-isolated processes (SIPs). Each SIP has its own data and code layout, and is independent from other SIPs. These SIPs behave like normal processes, but avoid the cost of task-switches. Protection in this system is provided by a set of rules called invariants that are verified by static program analysis. For example, in the memory-invariant states there must be no cross-references (or memory pointers) between two SIPs; communication between SIPs occurs via higher-order communication channels managed by the operating system. Invariants are checked during installation of the application. (In Singularity, installation is managed by the operating system.)

Notable quotes

“You, who know better than any one the motley world of cosmopolites, understand why I have confined myself to painting here only a fragment of it. That world, indeed, does not exist, it can have neither defined customs nor a general character. It is composed of exceptions and of singularities.”
— Paul Bourget, Cosmopolis (1892) Introduction
“It may be that our role on this planet is not to worship God but to create him.”
— Arthur C. Clarke Clarkfoundation.org
“Singularity is almost invariably a clue. The more featureless and commonplace a crime is, the more difficult it is to bring it home.”
— Sir Arthur Conan Doyle as Sherlock Holmes, The Boscombe Valley Mystery The Adventures of Sherlock Holmes, Strand Magazine (1891)
“Each word is a singularity, or is connected with a singularity, in our way of understanding existence.”
— Léon Rosenfeld (1904–74) As quoted in A Question of Physics: Conversations in Physics and Biology (1979), Paul Buckley and F. David Peat, Routledge and Kegan Paul, London, p. 29.
“The "hard" science-fiction writers are the ones who try to write specific stories about all that technology may do for us. More and more, these writers felt an opaque wall across the future. Once, they could put such fantasies millions of years in the future. Now they saw that their most diligent extrapolations resulted in the unknowable … soon.”
— Vernor Vinge, "The Coming Technological Singularity" (1993)
“The true human being … is the meaning of the universe. He is a dancing star. He is the exploding singularity pregnant with infinite possibilities.”
— David Zindell, The Broken God (1992)
