Claritas / Overview / Operating Systems

GLOBE Claritas Supported Operating Systems

GLOBE Claritas is supported on a wide range of operating systems, including:

  • Linux (RHEL6, UBUNTU 12.04)
  • Windows 7 (x86, x86_64 in 32 bit mode)

Please find a discussion of our Linux OS support below on this page.

Linux Support

We endeavour to support a wide range of Linux distributions. However as GLOBE Claritas requires the use of compilers at run time, we have to place some limits on the Linux systems we support.

Tier One Linux Support

The following systems have "Tier One Support" - we actively develop and/or test on these systems, maintain physical machines and conduct in depth full functionality testing on each release:

  • RHEL5 64-bit
  • RHEL6 64-bit
  • Ubuntu 12.04 64-bit

We would recommend all clients to work with one of these “Tier One Support” systems.

Tier Two Linux Support

We support the following operating systems as “Tier Two Support”

  • RHEL5, 32-bit
  • RHEL6, 32-bit
  • Ubuntu 12.04 32-bit

We maintain full virtual machines for each of these releases, and conduct a 2D and 3D land/marine functionality test cycle before each release.

What about other Linux Systems?

We use a lot of libraries and packages in GLOBE Claritas, and use specific functionality in certain versions of compilers. We do this to make the software as efficient as possible, and to enable our developers to focus on geophysics rather than recreating low-level libraries that already exist.

The systems we support have those packages available, and the .rpm and .deb install systems can be set to manage those dependencies. We can only support an operating system while it is supported by the provider.

I want to use Suse Linux, why don't you support it?

We have found that while Suse is popular in some sectors, the availability of packages, and their naming conventions, does not align with Ubuntu or RHEL.

The Suse release cycle is such that some packages - like python - present issues. While Suse departs from the other established Linuxes in this way, it's hard for us to maintain and support it as an outlier. It is possible to install and run GLOBE Claritas under Suse - a number of sites have done it. We can only offer limited help, and be warned that these sites have described it as "not for the faint hearted".

So if I run Suse or another Linux, can you support me?

We'll try. The most common issues we see are:

  • Packages not being available (we use a lot of open source packages, but you may need to recompile them for your O/S).
  • Graphic interface issues, due to the different X and compilers employed.
  • Unexpected failures when RAM gets tight, due to different compiler switches and so on.

It's hard to fix these without the systems in place - we usually try and suggest work-around flows that don't have the issue.

We won't leave you totally on your own, but we will limit the time and effort we put into keeping unsupported systems going. If you choose an unsupported OS, we may have to charge you for the additional support workload. Also, specific development work will incur additional costs, as outlined in your license agreement.

What's my best choice?

Up to you. We run a mix because:

  • RHEL is great for industrial scale networking, and having stable, bug free compilers and packages.
  • Ubuntu is great as a "windows replacement" for desktops, but less good on some aspects of networking, especially where other systems are in place.
