• NVRAM as Main Storage of Parallel File System

  Publikacja

  • A. Malinowski

  - Journal of Computer Science and Control Systems - Rok 2016

  Modern cluster environments' main trouble used to be lack of computational power provided by CPUs and GPUs, but recently they suffer more and more from insufficient performance of input and output operations. Apart from better network infrastructure and more sophisticated processing algorithms, a lot of solutions base on emerging memory technologies. This paper presents evaluation of using non-volatile random-access memory as a...

  Publikacja

  • M. Wróbel
  • J. Kaczmarek

  - Rok 2008

  One of the means to detect intruder's activity is totrace all unauthorized changes in a file system.Programs which fulfill this functionality are called fileintegrity checkers. This paper concerns modernapproach to file system integrity checking. It reviewsarchitecture of popular systems that are widely used inproduction environment as well as scientific projects,which not only detect intruders but also take actions tostop their...

• Parallel immune system for graph coloring

  Publikacja

  • J. Dąbrowski

  - Rok 2008

  This paper presents a parallel artificial immune system designed forgraph coloring. The algorithm is based on the clonal selection principle. Each processor operates on its own pool of antibodies and amigration mechanism is used to allow processors to exchange information. Experimental results show that migration improves the performance of the algorithm. The experiments were performed using a high performance cluster on a set...

• A distributed system for conducting chess games in parallel

  Publikacja

  • A. Rydzewski
  • P. Czarnul

  - Procedia Computer Science - Rok 2017

  This paper proposes a distributed and scalable cloud based system designed to play chess games in parallel. Games can be played between chess engines alone or between clusters created by combined chess engines. The system has a built-in mechanism that compares engines, based on Elo ranking which finally presents the strength of each tested approach. If an approach needs more computational power, the design of the system allows...

• Parallel computations in the volunteer based Comcute system

  Publikacja

  • P. Czarnul
  • J. Kuchta
  • M. Matuszek

  - Rok 2014

  The paper presents Comcute which is a novel multi-level implemen- tation of the volunteer based computing paradigm. Comcute was designed to let users donate the computing power of their PCs in a simplified manner, requiring only pointing their web browser at a specific web address and clicking a mouse. The server side appoints several servers to be in charge of execution of particular tasks. Thanks to that the system can survive...

• Implementation of FDTD-compatible Green's function on heterogeneous CPU-GPU parallel processing system

  Publikacja

  • T. Stefański

  - Progress in Electromagnetics Research-PIER - Rok 2013

  This paper presents an implementation of the FDTD-compatible Green's function on a heterogeneous parallel processing system. The developed implementation simultaneously utilizes computational power of the central processing unit (CPU) and the graphics processing unit (GPU) to the computational tasks best suited to each architecture. Recently, closed-form expression for this discrete Green's function (DGF) was derived, which facilitates...

• Optimization of Execution Time under Power Consumption Constraints in a Heterogeneous Parallel System with GPUs and CPUs

  Publikacja

  • P. Czarnul
  • P. Rościszewski

  - Rok 2014

  The paper proposes an approach for parallelization of computations across a collection of clusters with heterogeneous nodes with both GPUs and CPUs. The proposed system partitions input data into chunks and assigns to par- ticular devices for processing using OpenCL kernels defined by the user. The sys- tem is able to minimize the execution time of the application while maintaining the power consumption of the utilized GPUs and...

• Taking advantage of the shared explicit cache system based critical sections in the shared memory parallel architectures

  Publikacja

  • T. Madajczak

  - Rok 2006

  Artykuł prezentuje nową metodę implementacji sekcji krytycznych w równoległych architekturach z pamięcią współdzieloną, takich jak systemy zintegrowane wielowątkowe wieloprocesorowe. Metoda stanowi modyfikację i rozbudowanie metody zwanej Folding, dostępnej w procesorach sieciowych oraz jest w założeniach podobna do techniki zwanej cache-based locking. W porównaniu do dostępnych metod, nowa metoda usuwa problemy skalowalności i...
