168 Quadro Workstation User’s Guide
Chapter 9
Using NVIDIA Scalable Link Interface (SLI)
Overview of SLI for NVIDIA Quadro Cards
Professional users benefit by using SLI technology on dual NVIDIA Quadro GPUs to
span an OpenGL window across multiple displays, or to run a single application on
each GPU. The SLI connector offers dual GPU performance on a single display by
leveraging the capabilities of two NVIDIA Quadro GPUs.
SLI Modes for NVIDIA Quadro GPUs
There are three SLI functions available for NVIDIA Quadro GPUs:
SLI Frame Rendering Mode
SLI frame rendering combines two PCI Express graphics boards with an SLI
connector to transparently scale application performance on a single display by
presenting them as a single graphics card to the operating system.
SLI Multi-View Mode
SLI multi-view combines the power of two NVIDIA Quadro PCI Express graphics
boards to span a single hardware-accelerated OpenGL application window across
multiple displays, run a single application per GPU with multiple display outputs, or
enable other uses of two PCI Express graphics boards.
SLI Antialiasing Mode
SLI antialiasing combines the power of two PCI Express graphics boards to offer
higher quality antialiasing.
