LINX was ported later on Linux, works with same success on both OSE and Linux kernels. Is possible to interconnect a Linux machine with an OSE one and have a direct communication path between processes that run under different kernels.
Utilizing direct message passing, LINX scales from DSPs and microcontrollers to 64-bit CPUs. LINX is independent of the underlying processor, operating system, or interconnect, supports control and data plane applications over reliable and unreliable media.
LINX also supports any distributed system topology, from a single processor on a single blade, to large networks with complex cluster topologies deployed on hundreds of processors in a multi-rack system.
LINX enable application processes distributed across multiple operating systems, CPUs, and interconnects to communicate, as if they were running on the same CPU under the same operating system. LINX provides the same services to the application regardless of hardware, operating system, physical interconnect, and network topology.
LINX utilizes an innovative address map for connections that greatly enhances flexibility and scalability. Unlike other IPC models, which must maintain the entire system address map on every node in the system, LINX nodes store only the addresses needed for active connections.
In computer science, a microkernel is the near-minimum amount of software that can provide the mechanisms needed to implement an operating system (OS). These mechanisms include low-level address space management, thread management, and inter-process communication (IPC).
Non-Uniform Memory Access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory. The benefits of NUMA are limited to particular workloads, notably on servers where the data is often associated strongly with certain tasks or users.
A Beowulf cluster is a computer cluster of what are normally identical, commodity-grade computers networked into a small local area network with libraries and programs installed which allow processing to be shared among them. The result is a high-performance parallel computing cluster from inexpensive personal computer hardware.
In computer science, inter-process communication or interprocess communication (IPC) refers specifically to the mechanisms an operating system provides to allow the processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing.
A network interface controller is a computer hardware component that connects a computer to a computer network.
Quadrics was a supercomputer company formed in 1996 as a joint venture between Alenia Spazio and the technical team from Meiko Scientific. They produced hardware and software for clustering commodity computer systems into massively parallel systems. Their highpoint was in June 2003 when six out of the ten fastest supercomputers in the world were based on Quadrics' interconnect. They officially closed on June 29, 2009.
Enea AB is a global information technology company with its headquarters in Kista, Sweden that provides real-time operating systems and consulting services. Enea, which is an abbreviation of Engmans Elektronik Aktiebolag, also produces the OSE operating system.
XNU is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the macOS operating system and released as free and open-source software as part of the Darwin OS, which is the basis for the Apple TV Software, iOS, iPadOS, watchOS, and tvOS OSes. XNU is an abbreviation of X is Not Unix.
Linux Terminal Server Project (LTSP) is a free and open source terminal server for Linux that allows many people to simultaneously use the same computer. Applications run on the server with a terminal known as a thin client handling input and output. Generally, terminals are low-powered, lack a hard disk and are quieter and more reliable than desktop computers because they do not have any moving parts.
Ganglia is a scalable, distributed monitoring tool for high-performance computing systems, clusters and networks. The software is used to view either live or recorded statistics covering metrics such as CPU load averages or network utilization for many nodes.
Veritas Cluster Server is a high-availability cluster software for Unix, Linux and Microsoft Windows computer systems, created by Veritas Technologies. It provides application cluster capabilities to systems running other applications, including databases, network file sharing, and electronic commerce websites.
OpenVZ is an operating-system-level virtualization technology for Linux. It allows a physical server to run multiple isolated operating system instances, called containers, virtual private servers (VPSs), or virtual environments (VEs). OpenVZ is similar to Solaris Containers and LXC.
Transparent Inter Process Communication (TIPC) is an Inter-process communication (IPC) service in Linux designed for cluster wide operation. It is sometimes presented as Cluster Domain Sockets, in contrast to the well-known Unix Domain Socket service; the latter working only on a single kernel.
HAL is a software subsystem for UNIX-like operating systems providing hardware abstraction.
Binary-code compatibility is a property of computer systems meaning that they can run the same executable code, typically machine code for a general-purpose computer CPU. Source-code compatibility, on the other hand, means that recompilation or interpretation is necessary before the program can be run.
A computer cluster is a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software.
A lightweight kernel (LWK) operating system is one used in a large computer with many processor cores, termed a parallel computer.
The Slurm Workload Manager, formerly known as Simple Linux Utility for Resource Management (SLURM), or simply Slurm, is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters.
Linux on IBM Z is the collective term for the Linux operating system compiled to run on IBM mainframes, especially IBM Z and IBM LinuxONE servers. Similar terms which imply the same meaning are Linux on zEnterprise, Linux on zSeries, Linux/390, Linux/390x, etc. The terms zLinux or z/Linux are also sometimes used, but these terms are discouraged by IBM as they create the implication of an IBM-offered or IBM-distributed version of Linux, which is incorrect.
In computer science, shared memory is memory that may be simultaneously accessed by multiple programs with an intent to provide communication among them or avoid redundant copies. Shared memory is an efficient means of passing data between programs. Depending on context, programs may run on a single processor or on multiple separate processors.
