The NVIDIA System Management Interface, nvidia-smi, is a command-line interface to the NVIDIA Management Library, NVML. nvidia-smi provides Linux system administrators with powerful GPU configuration and monitoring tools. HPC cluster system administrators need to be able to monitor resource utilization (processor time, memory usage, etc.) on their systems. This resource monitoring is typically called accounting.
New in nvidia-smi with CUDA 5.5 is GPU process accounting, which enables nvidia-smi to log utilization data for GPUs on the system. In this episode of CUDACasts I show how to configure the NVIDIA display driver persistent mode and how to enable and use GPU process accounting.
