/*
|
|
|
|
|
* 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.

|
|
|
|
|
* and/or any of the GPL licenses you prefer.
|
|
|
|
|
* Feel free to use the code and modify as you see fit.
