如何通过该程序找到Nvidia GPU(特斯拉,费米或开普勒)的类型

Question

任何人都可以告诉我如何通过程序找到GPU类型(费米,特斯拉或开普勒),以便根据GPU类型调用正确的函数.

通过cudaDeviceProp.major,我能够通过他们的计算能力区分Fermi和Tesla.但我无法区分费米和开普勒.

有谁知道如何找到它.

Answer 1

要回答这个问题,请cudaDeviceProp.major=3确定当前的Kepler卡,cudaDeviceProp.major=2适用于Fermi和cudaDeviceProp.major=1G8x/G9x/G2xx卡,如此SDK deviceQuery输出所示:
