Integrity S2: a fault-tolerant Unix platform

Abstract: A description is given of Integrity S2, a fault-tolerant, Unix-based computing system designed and implemented to provide a highly available, fault-tolerant computing platform for Unix-based applications. Unlike some other fault tolerant computing systems, no additional coding at the user-level is required to take advantage of the fault-tolerant capabilities inherent in the platform. The hardware is an RISC-based triple-modular-redundant processing core, with duplexed global memory and I/O subsystems. The goals for this machine, the system architecture, its implementation and resulting performance, and the hardware and software techniques incorporated to achieve fault tolerance are discussed. Fault tolerance has been accomplished without compromising the programmatic interface, operating system or system performance. >

A light-weight component model for peer-to-peer applications

Abstract: Mobile peer-to-peer (P2P) computing applications involve collections of heterogeneous and resource-limited devices (such as PDAs or embedded sensor-actuator systems), typically operated in ad-hoc completely decentralized networks and without requiring dedicated infrastructure support. Short-range wireless communication technologies together with P2P networking capabilities on mobile devices are responsible for a proliferation of such applications, yet these applications are often complex and monolithic in nature due to the lack of lightweight component/container support in these resource-constrained devices. We describe our lightweight software component model P2Pcomp that address the development needs for mobile P2P applications. An abstract, flexible, and high-level communication mechanism among components is developed via a ports concept, supporting protocol independence, location independence, and (a)synchronous invocations; dependencies are not hard-coded in the components, but can be defined at deployment or runtime, providing late-binding and dynamic rerouteability capabilities. Peers can elect to provide services as well as consume them, services can migrate between containers, and services are ranked to support quality-of-service choices. Our lightweight container realization leverages the OSGi platform and can utilize various P2P communication mechanisms such as JXTA. A "smart space" application scenario demonstrates how P2Pcomp supports flexible and highly tailorable mobile P2P applications.

State of Cloud Applications and Platforms: The Cloud Adopters' View

Abstract: A recent survey of organizations with experience using cloud applications and platforms reveals that they are more bullish on the technology and more aggressive in their adoption plans than the overall market.

Dynamic injection of execution logic into main dynamic link library function of the original kernel of a windowed operating system

Abstract: Methods and system for dynamically injecting execution logic into shared memory spaces of a windowed operating system. An injection dynamic link library is loaded from an injection application into a pre-determined memory location within an area of shared memory within the windowed operating system. A main dynamic link library function within an original kernel dynamic link library including kernel functions for the windowed operating system is located from the injection dynamic link library. A jump command is inserted from injection dynamic link library within the main dynamic link library function in the kernel dynamic link library to create a modified kernel dynamic link library. The jump command jumps to an injection hook function within the injection dynamic link library whenever a new windowed operating system process is created. The injection hook function within the injection dynamic link library includes multiple injection functions that are executed by the windowed operating system prior to executing any other software applications whenever a new process is created in a windowed operating system. The methods and system of the present invention allow execution logic to be injected into new processes created by windowed operating systems using shared memory spaces such as Microsoft Windows 95/98. The execution logic is executed prior to any application software associated with the new processes. The methods and system of the present invention may be used for debugging aids, hooking other processes, tracing the execution of a process, and for other purposes.

The Splash 2 software environment

Abstract: Splash 2 is an attached special purpose parallel processor in which the computing elements are user programmable FPGA devices. The architecture of Splash 2 is designed to accelerate the solution of problems which exhibit at least modest amounts of temporal or data parallelism. Applications are developed by writing behavioral descriptions of algorithms in VHDL, which are then iteratively refined and debugged within the Splash 2 simulator. Once an application is determined to be functionally correct in simulation, it is compiled to a gate list and optimized by logic synthesis. The gate list is then mapped onto the FPGA architecture by automatic placement and routing tools to form a loadable FPGA object module. A C language library and a symbolic debugger comprise the execution environment. The Splash 2 system has been shown to be effective on a variety of applications, including text searching, sequence analysis, and image processing. >
