3.1. License
The license attached to AccessMod 5.0 is the GNU GPL V3. However, there is an additional WHO “TERMS OF USE AND SOFTWARE LICENSE AGREEMENT” that you must agree to in order to use AccessMod 5.0. Please read this document carefully when downloading AccessMod 5.0.
3.2. System Requirements
3.2.1. Introduction
AccessMod is based on a stack of several open-source libraries, packaged in a virtual machine, which makes it easy to use and install on any desktop computer, without needing to address software dependencies and configurations, licences, fees or operating system (AccessMod 5.0 can run under Windows, Mac, Linux,..). When up and running, AccessMod is available as a web application in a browser at this address: http://localhost:8080.
For those with extended technical knowledge, AccessMod can be installed natively (without a virtual machine) using provisioning scripts. For this installation option, see https://github.com/fxi/AccessMod_server for more information.
3.2.2. Virtualization Requirement
In order for AccessMod to run, you need to have allowed virtualization3 on your machine. On new computers, virtualization is done automatically. However, on older computers, you might have to turn this feature on. This is usually done by changing the virtualization parameter in the “BIOS” of the machine. If you do not know what the “BIOS” is, ask your IT manager (or the AccessMod workshop facilitator if you are following such a workshop) to help you with setting this up, as this is beyond the scope of this manual.
3.2.3. Software Requirements
Web browser
AccessMod uses a web browser for its user interface. This web browser connects to the virtual machine and all user inputs are done through the web browser.
We recommend you use the Chrome web browser from Google (https://www.google.com/chrome/) to get the best performance. However, AccessMod has also been successfully tested on Firefox, Safari, and Internet Explorer. Ensure that you have installed the latest version of the browser.
VirtualBox
To run AccessMod, you need the virtual machine manager, VirtualBox (https://www.virtualbox.org). VirtualBox is a free and open-source software that can run on any operating system.
3.2.4. Hardware Requirements
The minimum and recommended hardware requirements for running the virtual machine are as follows:
...
- Recommended requirements:
Memory (RAM): 8 GB
Disk space: 10 GB
Processor: 2-core CPU
3.2.5. RAM consumption
AccessMod has been developed to carry out the various analyses as quickly as possible. However, if you are working with large data sets, due to for example to the high-resolution of the raster data sets and/or a high number of health facilities, analyses can take a long time. If you want to run an extensive analysis, it is recommended to first ensure that a large amount of memory is available. It is recommended to have at least 8GB of memory in such cases.
