OpendTect system requirements
[Summary] Supported platforms
OpendTect needs good hardware with up-to-date drivers - especially for 3D graphics. You can run on:
OpendTect requires a recent well-patched OpenGL installation. OpenGL drivers should be updated at least every half year to ensure optimal performance and compliance.
OpendTect will attempt to use 'shading' - this means that some calculations are done on the graphics card. Unfortunately, not all cards behave properly. Very old cards will be no problem because they report that shading is not supported. Very new cards usually support it correctly (e.g. all nVidia-based cards and chipsets). Some older cards do give problems. These report that they support shading, but they support only part or so badly that the system almost stops. There are two settings for the user to cope with this:
Some cards (Like some ATI cards) support shading well but things go bad for
The default is:
OpendTect needs at least have 2 GB internal (RAM) memory available.
Therefore we would recommend machines with at least 4GB RAM, as the operating systems (especially Windows) will need their
share of this, too.
For Linux and MS Windows, a modern Intel or AMD processor is required. Although OpendTect will run on 2 GHz processors or even less, we recommend 3+ GHz multi-core for a good working environment. Note that OpendTect heavily uses all processors if necessary.
A modern Linux distribution is required. Minimum:
Linux distributions should be LSB compliant. You can check this using the command
For both SuSE and Red Hat-based distributions 64 bits releases are available. OpendTect is known to work under Debian, Ubuntu and other distributions, as well as earlier versions of the main distributions, too. Fedora usage is not recommended - although it may work it's the only distro that regularly fails to work in combination with OpendTect. This is probably because the graphics vendors do not support it well in terms of drivers.
Mac OS X
Minimum is Mac OS X (10.6) - thus Mac/Intel. Mac/PowerPC support is not available. A 3-button mouse is highly recommended.
Note: OpendTect v5 supports Mac OS X from 10.6 up to, and including, Yosemite. But El Capitan will not run OpendTect v5. OpendTect v6 supports all Mac OS X from 10.6 onwards, including El Capitan.
Windows 7, 8, 8.1 and 10 are supported. Windows needs to be updated with the latest updates from Microsoft.
If you have mega-surveys with Tera-bytes of data, and you want to do very advanced calculations, then you'll need the best you can get. What is best? The main idea is to minimize the bottlenecks.
It's clear that the number of variables is huge, and that it's simply very difficult to predict whether a certain configuration will be good enough for your specific needs.
