• PVM Web Cluster: integration of PVM clusters using Web services and CORBA.

  Publication

  • P. Czarnul

  - LECTURE NOTES IN COMPUTER SCIENCE - Year 2003

  Proponujemy nową architekturę i jej implementację PVM Web Cluster, która umożliwia łatwe zrównoleglanie wykonania zadań PVM zarówno na geograficznie rozproszone klastry PVM jak i wewnątrz nich. Uruchamianie zadań jest wykonywane poprzez wywołanie usługi sieciowej (Web service), która negocjuje najlepszy klaster (klastry) dla danego zadania i komunikuje się z klastrami za pomocą standardu CORBA.

  - LECTURE NOTES IN COMPUTER SCIENCE - Year 2003

  Artykuł przedstawia model lokalnej i zdalnej obsługi wyjątków w bibliotece PVM. Działający proces zostaje rozszerzony o możliwość zgłaszania zdalnych wyjątków do procesu nadrzędnego lub otrzymania akcji związanych z obsługą wyjątków. Przedstawiono wzorce obsługi wyjątków w aplikacjach rozproszonych oraz wprowadzono pojęcie Zdalnego Nadzorcy Wyjątków. Nadzorca może kontrolować każdy proces w maszynie wirtualnej (PVM).

• Improving flexibility and performance of PVM applications by distributed partial evaluation

  Publication

  - LECTURE NOTES IN COMPUTER SCIENCE - Year 2002

  A new framework for developing both flexible and efficient PVM applications is described. We propose Architecture Templates Interface (ATI) that allows to control application granularity and parallelism. To ensure high application efficiency we extend partial evaluation strategy into domain of distributed applications obtaining Distributed Partial Evaluation (DPE). Both ATI and DPE were implemented using a new distributed programming...

  - Year 2002

  The jPVM-oriented environment to support high performance computing required for the Endoscopy Recommender System (ERS) is defined. SPMD model of image matching is considered and its two implementations are proposed: Lexicographical Searching Algorithm (LSA) and Gradient Serching Algorithm (GSA). Three classes of experiments are considered and the relative degree of similarity and execution time of each algorithm are analysed....

  • A. Kalinowski
  • H. Krawczyk

  - Communications in Computer and Information Science - Year 2016

  The results of benchmarking tests of multi-level virtualized environments are presented. There is analysed the performance impact of hardware virtualization, container-type isolation and programming level abstraction. The comparison is made on the basis of a proposed score metric that allows you to compare different aspects of performance. There is general performance (CPU and memory), networking, disk operations and application-like...

• Development and tuning of irregular divide-and-conquer applications in DAMPVM/DAC

  Publication

  • P. Czarnul

  - Year 2002

  This work presents implementations and tuning experiences with parallel irregular applications developed using the object oriented framework DAM-PVM/DAC. It is implemented on top of DAMPVM and provides automatic partitioning of irregular divide-and-conquer (DAC) applications at runtime and dynamic mapping to processors taking into account their speeds and even loads by other user processes. New implementations of parallel applications...

  - Year 2015

  Along with Internet development, there were interactive applications which allow for remote sensing and photogrammetric analysis. An example of an application that can provide Earth images and make it possible to measure distances in these images is Google Earth. The authors, who have experience from 2001-2015 argue that it is possible and it is important to create more advanced photogrammetric network applications. In this there...
