CUDA and SLI bridge

Accelerated Computing CUDA CUDA Programming and Performance
1

Hi,

I have two GPU’s in my desktop and connected them with a SLI bridge. Does anybody know what SLI does with the performance of my CUDA programs? Because I read on multiple forums that you should disable SLI if you want to run CUDA programs? But what’s the motivation behind that?

Thank you!

SLI does not help or hinder CUDA in any way. In the past, the CUDA driver had a limitation and would only show you the first GPU if you had SLI enabled. That restriction has been removed, and now you will see both devices even if SLI is turned on. SLI is only beneficial to 3D rendering.
