There has been significant progress making standard Linux into a more responsive system for real-time applications. The low latency patches and the preemption patches have allowed guarantees on worst case interrupt response time at slightly above a millisecond. These guarantees today are only met when there is no networking or graphics activity in the system. The shielded processor concept dedi...

The CuPIDS project is an exploration of increasing information system security by dedicating computational resources to system security tasks in a shared resource, multi-processor (MP) architecture. Our research explores ways in which this architecture offers improvements over the traditional uni-processor (UP) model of security. There are a number of areas to explore, one of which has a protec...

This paper is devoted to the development of hypothesis about human brain “cartation”, i.e. spatially distributed structure of human brain systems for cogitative activities maintenance, containing neural parts with various degree of rigidity and different functional tasks (cartoids), which was suggested by Institute of Brain of the Russian Academy of Sciences (St.-Petersburg) under supervision o...

Landslide susceptibility mapping (LSM) is an important element of landslide risk assessment, but the process often needs to span multiple platforms and operation complex. This paper develops efficient user-friendly toolbox including whole LSM, known as SVM-LSM toolbox. The realizes based on a support vector machine (SVM), which can be integrated into ArcGIS or Pro platform. includes three sub-t...

High energy ion implantation forms, together with submicron lithography, trench technology, rapid thermal multiprocessing and simulation programs, are a powerful means of fabricating the tiny transistor structures of the future. Several crosssections of silicon devices, some of which are already known from the literature, are discussed. The benefits of implantations at energies between 200 and ...

We are currently investigating two di erent approaches to scalable shared memory Munin a distributed shared memory DSM system implemented entirely in software and Willow a true shared memory multiprocessor with extensive hardware support for scalability Munin allows parallel programs written for shared memory multiprocessors to be executed e ciently on dis tributed memory multiprocessors Unlike...

Preparing the SunOS/SVR4 kernel for today’s challenges: symmetric multiprocessing, multi-threaded applications, real-time, and multimedia, led to the incorporation of several innovative techniques. In particular, the kernel was re-structured around threads. Threads are used for most asynchronous processing, including interrupts. The resulting kernel is fully preemptible and capable of real-time...

With the price of computer hardware decreasing steadily and the scope of data processing applications ever rising, the problem of upgrading a computer system is omnipresent. The myriad of potential pitfalls includes losing an investment in purchased hardware and software, reprogramming applications, reformatting data files, retraining personnel, operating two different systems in parallel durin...
