OpendTect system requirements
[Summary] Supported platformsOpendTect needs good hardware with up-to-date drivers - especially for 3D graphics. You can run on:
Graphics:OpendTect requires a recent well-patched OpenGL installation. OpenGL drivers should be updated at least every half year to ensure optimal performance and compliance.
Intel/AMD: Recent nVidia and AMD (ATI) graphics cards/chipsets. Well behaved are nVidia GeForce 500, 600 and 700 series and AMD (ATI) Radeon 6xxx and 7xxx series.
Mac:Similar to the Intel/AMD platform.
Main stream and high-end GPUs within the series are recommended, since low-level GPUs keep showing poor performances through the generations.
Shading functionaly requires special GPU features, present in the cards listed above. Nevertheless, under Linux, only nVidia provides drivers capable of using the shading feature. If you can't see any colors on graphic elements, try disabling shading (Utilities-Look and Feel).
BackgroundOpendTect 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:
* Yes, use it if the card says it supports shading
* No, do not use it for VR even if the card says it supports shading
* If users get colorless inlines, time slices etc, they need to try disabling shading usage
* If users want to try improved volume rendering, they can try enabling that.
The access to these options is in the user's menu 'Utilities-Settings-Look&Feel'.
MemoryOpendTect should at least have 2 GB internal (RAM) memory available. Depending on the size of the surveys we recommend 8-16 GB on average. In special cases (big surveys or many data cubes) more memory may be required.
A rule of thumb is to have at least 10 times the displayed number of samples available. Thus, to be able to display 10 inlines with 2000 crosslines and 1000 samples per trace, you'll need a minimum of 200 million bytes of memory (i.e. 200 MB).
ProcessorFor 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.
LinuxA modern Linux distribution is required. Minimum:
For both SuSE and Red Hat-based distributions 32 or 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 XMinimum is Mac OS X (10.5) - thus Mac/Intel. Mac/PowerPC support is not available. A 3-button mouse is highly recomended.
MS WindowsWindows XP, Vista, 7 and 8 are supported and both 32 and 64 bits releases are available.
RecommendationsIf 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.
