Detailed Description

Runtime loader and wrapper for the NVIDIA NVML GPU management library.

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.
