nvml

问题 I am trying to execute some CUDA code which happens to have some NVML library functions like nvmlSystemGetDriverVersion. But, when I try to compile the code it says nvml.h not found. How should I install NVML on my system since nvml.h does not seem to be present on it? 回答1: A google search of "nvidia nvml" returns this as the first link. This page contains links for the API documentation. On that page, if you click on the Tesla Deployment Kit link, you can then find the download links

问题 I have been using NVML library to get the values of graphics and memory utilization for Rodinia benchmark suite. I observe that with different frequencies, the utilization of the same application shows different values. From the wiki link http://en.wikipedia.org/wiki/CPU_usage it seems it does not take into account the various stalls like memory, branch etc. What exactly is this utilization measuring during a time interval? And how come its value is varying with variation in frequency. Thanks
