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.


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

Single-user licence

An RLM licence which allows one named user to access their VSNi software on any device.

RLM server

The Reprise Licence Manager server which manages user access to VSNi software.


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

Enterprise licence

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

Campus licence

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


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.

Flexnet licence

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

Site reference

A code assigned by VSNi to uniquely identify the physical location of an organisation purchasing VSNi software. VSNi will ask you to provide this when you want to download a software upgrade.

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.

Trial licence

A licence 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.

Academic licence (Edu license)

For students and academics, such as university lecturers: a licence which provides access to VSNi software for use in relation to academic studies. These are 'full version' licences provided at preferential rates to support teaching in higher education settings.


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

Node-locked licence (Genstat only)

A node-locked licence lets you install your software only on a single device. Once the licence is activated your software and licence are locked to that device (but can be deactivated and moved to another device by emailing with a request).

Cloud licence server

A software licensing service that is hosted in the cloud (such as RLM). Users need Internet access so that the server can verify their licence when they log-in, but this adds flexibility. It allows the user to install and use their softare on multiple devices without the need for multiple licences.


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

On-premises licence

A licence 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.

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

A concurrent licence is a licence “count” i.e. an entitlement to a set number of licences.  A single-user concurrent licence enables the user to install and use the software on several devices, such as a work laptop, tablet or home PC. A multi-user concurrent licence can be shared across a large user community such as a research laboratory. Whenever a user runs the software our cloud-based licence server will “check out” their licence so that it becomes unavailable for use on other devices.
