C1060 GPU的奇怪设备特性

我正在运行一些代码，这些代码只需获取有关GPU的信息并打印出来。然而，我得到了非常奇怪（和变化）的数字。该代码只是一堆cudaDeviceProperties打印。

输出：

Global memory:   0mb
Shared memory:   136723055446kb
Constant memory: 136723055540kb
Block registers: 1359818672
Warp size:         32597
Threads per block: 1359826784
Max block dimensions: [ 32597, 1357152712, 32597 ]
Max grid dimensions:  [ 1359925824, 32597, -1220823104 ]

这些数字都没有任何意义，这让我认为卡/驱动程序/OS可能有问题。

英伟达SMI:340.93。操作系统：Ubuntu 14.04。

如果能对这里可能发生的事情提供任何帮助，我们将不胜感激。
