Licensing - Terminology | VSN International

Licensing Terminology

We appreciate that there is wide lexicon of terminology involved in software licensing. Some terminology may be familiar, some may not. To avoid any confusion here’s a summary of VSNi’s key licensing terminology to help.


The time period that a process remains in the running state.

RLM server

The server which manages user access to VSNi software.


More than one processor in a host system running our products.

Single-user license

An RLM license which allows one named user to access their VSNi software on any machine.


Someone logged-in and authenticated by the licensing service as being able to use the software.

Enterprise license

A single license which manages access to VSNi software for any number of users at a single organisation.

Campus license

Provides high volumes of simultaneous user access to VSNi software across a single university campus.

Site reference

A code assigned by VSNi to uniquely identify the physical location of an organisation purchasing VSNi software.

Concurrent license (also known as server, group or floating license)

The count value associated with an enterprise or cloud license which may be shared across a large user community. 


Multi-terminal or multi-seat computer is a particular configuration that allows a computer to be used by several people simultaneously.

Cloud installation

An installation of software and associated licensing service in a cloud environment rather than on a physical machine or server.


An application binary executable that has been successfully loaded by the operating system, Linux, Windows, or macOS, and placed into the running state.

Parallel processing

This is the breaking down of tasks that can be run simultaneously on different processors. In ASReml-SA the tasks are parts of the algorithm that are calculated in parallel.

Virtual machine (VM)

The emulation of a physical computer created by providing all of the attributes of a specific operating system via a remote server such that to the user it acts like a physical computer.

Flexnet license

A floating Genstat license that is installed on an On-Premises Flexnet Server system. Each Genstat installation requires a license file that points to the On-Premises Flexnet Server system.

Academic license (Edu license)

A license which provides access to VSNi software for use in relation to academic studies. These are 'full version' licenses provided at preferential rates to support teaching in higher education settings.

Node-locked license Also known as Standalone or Machine-locked

A node-locked license is an encrypted ‘key’ that is locked to a specific machine. This is only applicable for Genstat licensing and RLM Student licenses (although Student licenses do require internet access to use).

Student license

A license which provides access to VSNi software for use by students in relation to their academic studies. These may have reduced functionality, and may be locked to a specific computer. Academic licenses (Edu license) provide full access (see above).

Trial license

A license which provides access to VSNi software for a short period of time, typically 14 but possibly up to 30 days. This is to allow potential customers to assess the suitability of the software to their application and to understand the set-up requirements.


The time period between the startup of the licensed product until it has completed its task and terminated. An enterprise license user may run two sessions for each license they successfully checkout from the available shared license. A cloud license user may run four per shared license.


A single access of the software. The license may allow for more than one concurrent instance. The same user may access more than one instance concurrently if the software license allows for this. Equally each instance might be accessed by a single user, allowing multiple users to access the software concurrently.

Cloud license server

A software licensing service that is hosted in the cloud (such as RLM). Users need internet access to achieve license authentication when they log-in, but this adds flexibility. It allows the user to have multiple downloads of the software to access on different machines without the need for multiple licenses.

On-premises license

A license service which is hosted on a customer’s own machine or server. No internet connection is required to use VSNi software (after initial server setup and activation). Where users cannot access the internet, perhaps due to specific IT protocols within their organisation, then we can provide a bespoke ‘on-premises’ licensing service. This will be for larger installations only and will carry a premium charge.


A container, in this context, is a term used to describe a very specific type of virtual machine. It typically has a single application installation, such as ASReml-SA or ASReml-R, that is made available through its management platform. VSNi currently utilise the Docker Machine to manage our containers. Several service providers such as AWS and Azure offer services to support the deployment of this type of container image.
