Sharing and protection in a single-address-space operating system

by Jeffrey S. Chase, Henry M. Levy, Michael J. Feeley, Edward D. Lazowska - ACM Transactions on Computer Systems , 1994
"... This article explores memory sharing and protection support in Opal, a single-address-space operating system designed for wide-address (64-bit) architectures. Opal threads execute within protection domains in a single shared virtual address space. Sharing is simplified, because addresses are context ..."

Sharing and Protection in a Single Address Space Operating System

by Jeffrey S. Chase, Henry M. Levy, Michael J. Feeley, Edward D. Lazowska , 1994
"... The appearance of 64-bit address space architectures, such as the DEC Alpha, HP PA-RISC, and MIPS R4000, signals a radical shift in the amount of address space available to operating systems and applications. This shift provides the opportunity to reexamine fundamental operating system structure ..."

The Mungi single-address-space operating system

by Gernot Heiser, Kevin Elphinstone, Jerry Vochteloo, Stephen Russell - Software— Practice and Experience , 1998
"... Abstract Single-address-space operating systems (SASOS) are an attractive model for making the best use of the wide address space provided by the latest generations of microprocessors. SASOS remove the address space boundaries which make data sharing between processes difficult and expensive in trad ..."

Architectural Support for Single Address Space Operating Systems

by Eric J. Koldinger, Eric J. Koldinger, Jeffrey S. Chase, Jeffrey S. Chase, Susan J. Eggers, Susan J. Eggers , 1992
"... Recent microprocessor announcements show a trend toward wide-address computers: architectures that support 64 bits of virtual address space. Such architectures facilitate fundamentally new operating system organizations that promote efficient data sharing and cooperation, both between complex applic ..."

applications and between parts of the operating system itself. One such organization is the single address space operating system, in which all processes run within a single global virtual address space; protection is provided not through conventional address space boundaries, but through protection domains

Autograph: Toward automated, distributed worm signature detection

by Hyang-ah Kim - In Proceedings of the 13th Usenix Security Symposium , 2004
"... Today’s Internet intrusion detection systems (IDSes) monitor edge networks ’ DMZs to identify and/or filter malicious flows. While an IDS helps protect the hosts on its local edge network from compromise and denial of service, it cannot alone effectively intervene to halt and reverse the spreading o ..."

Fbufs: A High-Bandwidth Cross-Domain Transfer Facility

by Peter Druschel, Larry L. Peterson - in Proceedings of the Fourteenth ACM symposium on Operating Systems Principles , 1993
"... We have designed and implemented a new operating system facility for I/O buffer management and data transfer across protection domain boundaries on shared memory machines. This facility, called fast buffers (fbufs), combines virtual page remapping with shared virtual memory, and exploits locality in ..."

RacerX: Effective, Static Detection of Race Conditions and Deadlocks

by Dawson Engler, Ken Ashcraft - SOSP'03 , 2003
"... This paper describes RacerX, a static tool that uses flowsensitive, interprocedural analysis to detect both race conditions and deadlocks. It is explicitly designed to find errors in large, complex multithreaded systems. It aggressively infers checking information such as which locks protect which o ..."

Linkage in the Nemesis Single Address Space Operating System

by Timothy Roscoe - ACM OPERATING SYSTEMS REVIEW , 1994
"... The recent interest in single address space operating systems has resulted in a number of papers, most of which gloss over the issues of linking programs to run in multiple protection domains. Some of the confusion about 64-bit address spaces is due to the almost pervasive use of UNIX and UNIXlike ..."
