Hardware acceleration

EWSA provides hardware acceleration (i.e. runs much faster) on most modern NVIDIA and ATI video cards, and on Tableau TACC1441 hardware accelerators.

You can use NVIDIA GeForce 8-, 9-, 100-, 200-, 400- and 500-series or Quadro cards; Tesla is also supported. Full list of supported devices can be found here. If you have multiple cards, you need to disable SLI (either in driver or by physically disconnecting the cards).

EWSA also supports ATI Stream(tm) Technology, in particular Radeon 6000 Series, Radeon 5000 Series and Radeon HD 4000 Series.

Alternatively, you can use Tableau TACC1441 accelerators.

Whether you have NVIDIA or ATI card to use with EWSA, you should also have the latest drivers installed (supported operating systems: Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008 and Windows 7; 32-bit and 64-bit).

The maximum supported number of GPU devices is 8 (4x PCI-Express slots on motherboard, each with double-GPU device such as NVIDIA GeForce GTX 590 or ATI Radeon HD 6990).
