Some boards in a cluster have access to better cooling than others. By default the Tesla K40 ships with the core clock set to the base clock. HPC workloads can have one or more characteristics as described. When selecting one of the supported boost clocks a good strategy is to characterize the workload with the available boost clocks. -
Page 8: Api For Nvidia Gpu Boost On Tesla
Overview API FOR NVIDIA GPU BOOST ON TESLA Tesla K40 gives full control to end-users to select the core clock frequency via NVML or . NVML is a C-based API for monitoring and managing the various states of nvidia-smi Tesla products. It provides a direct access to submit queries and commands via nvidia- . -
Page 9: Table 1. Nvidia-Smi Commands
To allow “non-root” access to change nvidia-smi -acp 0 graphics clock When using non-default applications clocks, driver persistence mode should be enabled. Persistence mode ensures that the driver stays loaded even when no NVIDIA CUDA ® ® or X applications are running on the GPU. This maintains current state, including requested applications clocks. -
