When you install the drivers for an Nvidia GPU, they come packed with a couple of weighty pieces of software - Nvidia GeForce Experience and Nvidia Control Panel. Join the GeForce community. Browse categories, post your questions, or just chat with other members. Knowing all that, we have written a simple standalone D3D12 application (SetStablePowerState.exe) that can lock and unlock the current GPU Core Clock frequency for any NVIDIA GPU with GPU Boost. The GPU Core Clock frequency gets instantly locked when launching this app, so it can be launched anytime you want to start/stop profiling GPU times.

NVIDIA GPU Boost™ is a feature available on NVIDIA® GeForce® products and NVIDIA® Tesla® products. It makes use of any power headroom to boost application performance. In the case of Tesla, the NVIDIA GPU Boost feature is customized for compute intensive workloads running on clusters. This application note is useful for anyone who wants to take advantage of the power headroom on the Tesla K40 in a server or within a workstation. Note that GPU Boost is a system setting, which means that this Pro Tip applies to any user of a CUDA-accelerated application, not just developers.

GPU Boost continuously monitors power and temperatures, helping your GPU use every bit of performance without exceeding safety or comfort limits.

The Tesla K40 board targets a specific power budget (235W) when running a highly optimized compute workload, but HPC workloads vary in power consumption and profile, as the graph in Figure 1 shows. This shows that for many applications there is power headroom. NVIDIA GPU Boost for Tesla allows customers to use available power headroom to select higher graphics clocks using NVML or nvidia-smi.

In an old post, by Saad Rahim, he benchmarks two applications with varying clocks on K40: Reverse Time Migration (RTM), a depth migration algorithm used to image complex geologies; and a Finite-difference time-domain (FDTD) electromagnetic solver. Just by using GPU Boost, he was able to measure a 18.5% performance increase in RTM versus base clocks, and over 14% improvement in FDTD, as shown in Figure 2.

You may notice a slightly superlinear performance improvement in Figure 2 for the RTM TTI benchmark. This may seem surprising, but it has a simple explanation, as described by the Tesla Application Note on GPU Boost:

In the Tesla K40, the NVIDIA GPU Boost capability allows end users to specify the boost clock which is just the core clock. The memory clock remains at 3 GHz. However, selecting higher boost clocks does improve the effective memory bandwidth utilization for workloads that are sensitive to memory bandwidth. With higher boost clocks some workloads may even see improved PCIe transfer rates. Therefore, NVIDIA GPU Boost on the Tesla K40 helps workloads which are sensitive to core clocks, power headroom and also helps workloads that may be more sensitive to memory bandwidth than core clocks.

You can find more information on GPU Boost, including instructions, scenarios, and best practices in the Tesla Application Note on GPU Boost.

GPU Boost gets an upgrade

Gpu Boost 2.0 Download

You're probably already familiar with NVIDIA's method of dynamically boosting clock speeds until the cards hit a pre-determined power or temperature limit. The GPU Boost algorithm makes clock speed adjustments based on a raft of factors, tweaking speeds and voltages many times per second.

With its Turing cards, NVIDIA is introducing the fourth iteration of GPU Boost, complete with the ability for users to manually adjust the algorithms that GPU Boost uses to determine clock speeds. Filehippo idm crack download.

The algorithms for GPU Boost 3.0 were completely inside the driver and not exposed to users. https://ameblo.jp/vercunope1972/entry-12633233834.html. GPU Boost 4.0 changes this by allowing you to modify the various curves to increase performance. Most users probably won't have much use for this, but overclockers and enthusiasts will enjoy having more manual controls available.
