• Performance evaluation of Unified Memory with prefetching and oversubscription for selected parallel CUDA applications on NVIDIA Pascal and Volta GPUs

  Publikacja

  • M. Knap
  • P. Czarnul

  - JOURNAL OF SUPERCOMPUTING - Rok 2019

  The paper presents assessment of Unified Memory performance with data prefetching and memory oversubscription. Several versions of code are used with: standard memory management, standard Unified Memory and optimized Unified Memory with programmer-assisted data prefetching. Evaluation of execution times is provided for four applications: Sobel and image rotation filters, stream image processing and computational fluid dynamic simulation,...

• Performance evaluation of unified memory and dynamic parallelism for selected parallel CUDA applications

  Publikacja

  • Ł. Jarząbek
  • P. Czarnul

  - JOURNAL OF SUPERCOMPUTING - Rok 2017

  The aim of this paper is to evaluate performance of new CUDA mechanisms—unified memory and dynamic parallelism for real parallel applications compared to standard CUDA API versions. In order to gain insight into performance of these mechanisms, we decided to implement three applications with control and data flow typical of SPMD, geometric SPMD and divide-and-conquer schemes, which were then used for tests and experiments. Specifically,...

• Investigation of Parallel Data Processing Using Hybrid High Performance CPU + GPU Systems and CUDA Streams

  Publikacja

  • P. Czarnul

  - COMPUTING AND INFORMATICS - Rok 2020

  The paper investigates parallel data processing in a hybrid CPU+GPU(s) system using multiple CUDA streams for overlapping communication and computations. This is crucial for efficient processing of data, in particular incoming data stream processing that would naturally be forwarded using multiple CUDA streams to GPUs. Performance is evaluated for various compute time to host-device communication time ratios, numbers of CUDA streams,...

• Memory and Imagination: Artwork as a Form of Testimony

  Publikacja

  • J. Kabrońska

  - Rok 2016

  As the generation of witnesses is passing away and the testimonies of Shoah survivors are replaced by an inherited, culturally constructed memory - post-memory – art becomes a meaningful landmark in the landscape of memory. Although the narration of history - being the researchers’ discourse rather than an objective view - has been considered to a certain extent fictitious, the difference between real and fictional, between remembering...

• Shape-Memory Polyurethane Polymers

  - ACS SYMPOSIUM SERIES - Rok 2021

  Polyurethanes (PUs) are one of the most widely used polymers in research and industry. They can be synthesized from chemical sources and natural sources. PUs are a very useful class of polymers and exhibit many desirable properties that can be exploited in various applications. PUs are formed by the reaction between polyols and isocyanates. A wide variety of polyols and isocyanates are available for synthesis, and hence we can...

• Semantic Memory for Avatars in Cyberspace

  Publikacja

  • J. Szymański
  • T. Sarnatowicz
  • W. Duch

  - Rok 2005

  Avatars that show intelligent behavior should have an access to general knowledge about the world, knowledge that humans store in their semantic memories. The simplest knowledge representation for semantic memory is based on the Concept Description Vectors (CDVs) that store, for each concept, an information whether a given property can be applied to this concept or not. Unfortunately large-scale semantic memories are not available....

  - Materials - Rok 2021

  Smart materials are much discussed in the current research scenario. The shape memory effect is one of the most fascinating occurrences in smart materials, both in terms of the phenomenon and its applications. Many metal alloys and polymers exhibit the shape memory effect (SME). Shape memory properties of elastomers, such as rubbers, polyurethanes, and other elastomers, are discussed in depth in this paper. The theory, factors...
