====== RN-29: p.d 5.4 System Requirements ====== 


===== Purpose =====
The purpose of this document is to provide an indication of the minimum and recommended system requirements to be able to run the p.d software. These requirements are based on versions 5.4+.

===== decimal Launcher System Requirements =====

p.d uses the decimal Launcher to manage installation, updates, and provide initial user authentication. As such, the decimal Launcher is required to be installed prior to using p.d.
Refer to the [[decimalauncher:decimallauncher#system_requirements|decimal Launcher System Requirements]] guide for further details.

===== Support Web Browsers (.decimal Direct) =====

| Microsoft Edge | Latest stable version supported |
| Chrome         | Latest stable version supported |
| Firefox        | Latest stable version supported |

===== Minimum System Requirements =====

| Processor | 2 GHz Intel Pentium or equivalent processor |
| RAM       | 2 GB RAM |
| Video     | OpenGL compatible graphics card |
| Display   | 1440x900 minimum resolution |
| Operating System | Windows 10 64-bit |
| Hard Disk | 100MB for application, additional space required for patient data (approx. 100MB per patient /w images, 5MB per patient w/o images |
|Connectivity | Active internet connection is required (see below) |

===== Recommended System Requirements =====

| Processor | Dual or quad core processor (multiple processors improve performance during design operations) |
| RAM       | 4 GB RAM |
| Video     | NVIDIA graphics card with at least 512MB of dedicated memory |
| Display   | 1920x1080 |

===== Network Requirements =====

p.d utilizes port 443 (HTTPS) to communicate with .decimal Direct while connected to the internet. This port must be open to passive communication with external addresses from the machine that is running p.d. Note that all communication is initiated from p.d (i.e., there should be no need to forward ports to the p.d workstation), however, you must ensure that the following addresses be allowed to communicate with the p.d workstation in order for the software to function properly:

| Port 443 | direct.dotdecimal.com (64.128.252.104)\\ (used for authentication, ordering, and order status updates) |
| Port 443 | decimal Launcher IPs (See [[decimalauncher:decimallauncher#system_requirements|Launcher Network Requirements Guide]])\\ (used for authentication to Auth0 servers & application downloads) |
