Atomic (magazine) – Introduction

”Atomic” (or ”Atomic MPC”) is a monthly Australian magazine and online community dedicated to computing and technology, with an emphasis on gaming, modding and computer hardware. ”Atomic” is marketed at technology enthusiasts and covers a number of topics that are not normally found in mainstream PC publications. Such topics include, but are not limited to, [...]

Amstrad PCW – Introduction

Amstrad PCW series was a range of personal computers produced by British company Amstrad from 1985 to 1998, and also sold under licence in Europe as the “Joyce” by the German electronics company Schneider in the early years of the series’ life. When it was launched, the cost of a PCW system was under 25% [...]

VirtualGL – VirtualGL’s Solution

VirtualGL uses “GLX forking” to perform OpenGL rendering on the application server. Unix and Linux OpenGL applications normally send both GLX commands and ordinary X11 commands to the same X display. The GLX commands are used to bind OpenGL rendering contexts to a particular X window, obtain a list of pixel formats that the X [...]

Scheduling (computing) – Introduction

Scheduling is a key concept in computer multitasking, multiprocessing operating system and real-time operating system designs. Scheduling refers to the way processes are assigned to run on the available CPUs, since there are typically many more processes running than there are available CPUs. This assignment is carried out by softwares known as a scheduler and [...]

Elxsi – Introduction

Elxsi (now Tata Elxsi) was a minicomputer manufacturing company established in the late 1970s along with a host of other competitors (Trilogy Systems, Sequent, Convex Computer). The Elxsi processor was an Emitter Coupled Logic (ECL) design that featured a 50 nanosecond clock, a 25 nanosecond backpanel bus, IEEE floating point arithmetic and a 64-bit architecture. [...]

Virtual resource partitioning – Introduction

LINUX Operating System

Virtual resource partitioning (VRP) is an operating system-level virtualization technology that allocates computing resources (such as CPU & I/O) to transactions. Conventional virtualization technologies allocate resources on an operating system (Windows, Linux…) wide basis. VRP works 2 levels deeper by allowing regulation and control of the resources used by specific transactions within an application. In [...]

Virtual memory – Paged virtual memory

Virtual Operating Systems

Almost all implementations of virtual memory divide the virtual address space of an application program into pages; a page is a block of contiguous virtual memory addresses. Pages are usually at least 4 KiB (4×1024 bytes) in size, and systems with large virtual address ranges or large amounts of real memory generally use larger page [...]

PCI hole – Memory remapping

Virtual Operating Systems

Another way to remove the PCI hole, which is only useful for 64-bit operating systems and those 32-bit systems that support the Physical Address Extension method described above, is to “remap” some or all of the memory between the 2 gigabytes and 4 gigabytes limits to addresses above 4 gigabytes. This needs to be supported [...]

Cross-platform – Platforms

Solaris Operating System

A platform is a combination of hardware and software used to run software applications. A platform can be described simply as an operating system or computer architecture, or it could be the combination of both. Probably the most familiar platform is Microsoft Windows running on the x86 architecture. Other well-known desktop computer platforms include Linux/Unix [...]

Winbatch – WinBatch Extenders

NetWare Operating System

Extenders add additional commands to the WinBatch programming language. A few popular extenders are included with the default WinBatch installer, with additional extenders available for download. * ADSI Extender – Provides access to Microsoft’s Active Directory Service Interfaces. * Control Manager Extender – Allows control of most standard Windows controls displayed on the screen, allowing [...]
