|
* A trivial little dlopen()-based wrapper library for the |
|
* NVIDIA NVML library, to allow runtime discovery of NVML on an |
|
* arbitrary system. This is all very hackish and simple-minded, but |
|
* it serves my immediate needs in the short term until NVIDIA provides |
|
* a static NVML wrapper library themselves, hopefully in |
|
* CUDA 6.5 or maybe sometime shortly after. |
|
* |
|
* This trivial code is made available under the "new" 3-clause BSD license, |
|
* and/or any of the GPL licenses you prefer. |
|
* Feel free to use the code and modify as you see fit. |
