  - Rok 2019

  —In the paper we present investigation of performance-energy trade-offs under power capping using modern processors. The results are presented for systems targeted at both server and client markets and were collected from Intel Xeon E5 and Intel Xeon Phi server processors as well as from desktop and mobile Intel Core i7 processors. The results, when using power capping, show that we can find various interesting combinations of...

• GPU Power Capping for Energy-Performance Trade-Offs in Training of Deep Convolutional Neural Networks for Image Recognition

  - Rok 2022

  In the paper we present performance-energy trade-off investigation of training Deep Convolutional Neural Networks for image recognition. Several representative and widely adopted network models, such as Alexnet, VGG-19, Inception V3, Inception V4, Resnet50 and Resnet152 were tested using systems with Nvidia Quadro RTX 6000 as well as Nvidia V100 GPUs. Using GPU power capping we found other than default configurations minimizing...

  • J. Proficz
  • P. Czarnul

  - Annals of Computer Science and Information Systems - Rok 2018

  In the paper we present extensive results from analyzing energy/performance trade-offs with power capping observed on four different modern CPUs, for three different parallel applications such as 2D heat distribution, numerical integration and Fast Fourier Transform. The CPU tested represent both multi-core type CPUs such as Intel⃝R Xeon⃝R E5, desktop and mobile i7 as well as many-core Intel⃝R Xeon PhiTM x200 but also server, desktop...

• Performance/energy aware optimization of parallel applications on GPUs under power capping

  Publikacja

  • A. Krzywaniak
  • P. Czarnul

  - Rok 2020

  In the paper we present an approach and results from application of the modern power capping mechanism available for NVIDIA GPUs to the bench- marks such as NAS Parallel Benchmarks BT, SP and LU as well as cublasgemm- benchmark which are widely used for assessment of high performance computing systems’ performance. Specifically, depending on the benchmarks, various power cap configurations are best for desired trade-off of performance...

• Modeling and Simulation for Exploring Power/Time Trade-off of Parallel Deep Neural Network Training

  Publikacja

  • P. Rościszewski

  - Procedia Computer Science - Rok 2017

  In the paper we tackle bi-objective execution time and power consumption optimization problem concerning execution of parallel applications. We propose using a discrete-event simulation environment for exploring this power/time trade-off in the form of a Pareto front. The solution is verified by a case study based on a real deep neural network training application for automatic speech recognition. A simulation lasting over 2 hours...

• Expedite EM-driven generation of Pareto-optimal trade-off curves for variable-turn on-chip inductors

  Publikacja

  • S. Kozieł
  • P. Kurgan

  - IET Microwaves Antennas & Propagation - Rok 2018

  This work presents a novel approach to computationally efficient Pareto front identification for variable-turn on-chip inductors. The final outcome is a set of solutions that correspond to the best trade-offs between conflicting design objectives. Here, we consider minimising inductor area and, simultaneously, maximising its quality factor, while maintaining a specified inductance value at a given operating frequency. As opposed...

  - Rok 2003

  Artykuł dotyczy optymalizacji konstrukcji i technologii szyny doprowadzenia zasilania do pojedynczej gałęzi falownika średniego napięcia. Dla szeregowego układu złożonego z trzech modułów elektroizolowanych (6 par tranzystorów i diod) rozważono warianty geometrii szyny zasilania przy uwzględnieniu wypadkowej indukcyjności obwodu komutacyjnego. Wyznaczono główne składniki indukcyjności rozproszenia oraz wykazano jej wpływ na przepięcia...
