CUDA 그리고 SLI

결론만 말하자면, SLI는 복수개의 (대개는 2개지만) 그래픽 카드를 1개의 논리 그래픽 카드로 만들어서 사용하는 것이므로,
CUDA에서 1개의 그래픽 카드로 인식, BOINC에서 1개분의 속도 밖에 나오지 않는 것으로 추측된다.

Posted 10 Feb 2009 13:42:02 UTC Correction. SLI means that you have two or more graphics cards working as one, with a single output. BOINC will recognize all the cards, but it will only use one card due to it being used in SLI mode. Seti CUDA will then only work on one card.

Posted 31 Jan 2009 19:22:14 UTC SLI basically combines 2 (or more) matched GPU devices into 1 logical GPU device. When in SLI mode, the system sees only 1 logical GPU and unfortunately for CUDA this means that it only has visibility to 1 physical device (not 2, 3 or 4). Disabling SLI mode for CUDA is best because it allows SETI to take advantage of each GPU as its own device. [링크 : http://boinc.berkeley.edu/dev/forum_thread.php?id=3592]
