 Encyclopedia: Network of Workstations
A computer workstation, often colloquially referred to as workstation, is a high-end general-purpose microcomputer designed to be used by one person at a time and which offers higher performance than normally found in a personal computer, especially with respect to graphics, processing power and the ability to carry...
A COW or Cluster of Workstations is sometimes used as an alternate term, however that term might be used to suggest a potential of faster network communications between workstations.
Distributed computing is the process of aggregating the power of several computing entities to collaboratively run a single computational task in a transparent and coherent way, so that they appear as a single, centralized system.

 Securing Desktop Workstations   (Site not responding. Last check: 2007-11-06)
Securing desktop workstations should be a significant part of your network and information-security strategy because of the sensitive information often stored on workstations and their connection to the rest of the networked world.
Although this module focuses on securing desktop workstations, many of the practices are also applicable to securing network servers or other computers on your network.
We recognize that security of the workstation also depends on security of the network to which it is connected, and we plan to describe network security practices in subsequent modules.

 Lasa KnowledgeBase - Troubleshooting and Resources - Network not Working? Troubleshooting Network Problems - ...
Network problems come in all shapes and sizes and can be incredibly easy to sort out (replacing a network cable, for example) to ridiculously complicated and expensive (replacing a server, maybe…).
However, as a brief introduction, each computer on the network is given a numerical address in the format xxx.xxx.xxx.xxx (known as an IP address) so that network traffic ends up the correct place.
On peer-to-peer networks it may be that the ADSL router has a DHCP service which is used by the computers, or possibly they will have fixed (static) addresses that will have been allocated to the machines when they were configured by whoever set up the network.

Networks of workstations have advanced to the point where they can be considered as candidates for the next generation of supercomputers.
Unfortunately, operating systems for current workstations were designed for autonomous operation in an untrusted environment and do not pass the full performance of the hardware available on to the application.
Our research is aimed at providing the network of workstations with the operating system support appropriate to the environment, that is, low-latency communication and cooperative scheduling, while still maintaining the inter-process protection that users have come to expect from the single-workstation environment.

In A Case for NOW (Network of Workstations), the authors start off by showing that the cost of producing faster computers is absorbed more easily by personal computers and workstations than mainframes and supercomputers, because such a high volume of them are sold.
While, NOW is a collection of workstations that provides both the interactive performance of a dedicated workstation and the aggregate resources of the network for demanding sequential and parallel programs.
Many businesses could now find a use for all the old computers they were going to have to weed out of the system anyway.

 Not your average client/server network
In systems such as Linux NOW that were used in the past, the biggest headaches were security and the integrity of the distributed file system.
In a decentralized network of distributed workstations, every client is actually a part of the "server," giving users a multitude of access points to important system and configuration files.
While an answer to this security conundrum is still in development at Progeny, the company's goal for Linux NOW is to have a network in which users to log on to a "system" where user rights and access policies are enforced, thus keeping important system files behind a protective curtain.

In a networked environment it is not uncommon for additional users to log in by sitting at a terminal and using the communication server to connect their terminal to the workstation.
In the early days of local area networking there were few standards and a wide variety of performance levels, and thus different protocols and services evolved in different settings.

 Towards Process Management on a Network of Workstations   (Site not responding. Last check: 2007-11-06)
These tests include: run-times on different workstation models, effect of sharing the processor, effect of flushing the file cache between runs, available parallelism, the cost of remote execution, and the effect of network over-utilization.
However, when running jobs on the workstations, the scheduling policy must not be unfair to some of the users by overcommitting them to one particular user.
This may suggest that the scheduling policy should try to monitor network activity (and the source of it), and perhaps alter its decisions based on current on-goings.

 Distributed Finite-Element Analysis on Network of Workstations — Algorithms   (Site not responding. Last check: 2007-11-06)
We present distributed algorithms for the finite–element (FE) analysis of large structures on a loosely coupled multicomputer such as a cluster of inexpensive workstations.
To account for the slow communication speed of the ethernet network connecting workstations, techniques such as redundant computations to eliminate communication, efficient data distribution, and algorithmic restructuring to reduce communication frequency have been developed to coarsen task granularity.
Due to the general nature of the data distribution scheme, the algorithms are versatile and can be applied to the analysis of unstructured FE domains consisting of a combination of various types of elements.
