• Autofagia: mechanizm molekularny, apoptoza i nowotwory = Autophagy: molecular mechanism, apoptosis and cancer

  Publikacja

  • J. Polewska

  - Postępy Higieny i Medycyny Doświadczalnej - Rok 2012

  W pracy omówiono molekularny mechanizm autofagii oraz najważniejsze szlaki sygnałowe uczestniczące w regulacji przebiegu tego procesu w komórkach nowotworowych. Omówiona została również dwojaka rola autofagii w procesie nowotworzenia oraz skutki zarówno indukcji, jak i inhibicji autofagii w terapii przeciwnowotworowej

• Distributed NVRAM Cache – Optimization and Evaluation with Power of Adjacency Matrix

  Publikacja

  • A. Malinowski
  • P. Czarnul

  - Rok 2017

  In this paper we build on our previously proposed MPI I/O NVRAM distributed cache for high performance computing. In each cluster node it incorporates NVRAMs which are used as an intermediate cache layer between an application and a file for fast read/write operations supported through wrappers of MPI I/O functions. In this paper we propose optimizations of the solution including handling of write requests with a synchronous mode,...

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Rok 2016

  The paper presents the proposition of caches implementation for map presentation in distributed information data exchange system. The concept of cache service is described in the context of distributed information data exchange system elements which control and present on maps positions and other identification data of vessels and other suspicious objects on the territorial sea, sea-coast and the internal sea-waters. The proposed...

• A Solution to Image Processing with Parallel MPI I/O and Distributed NVRAM Cache

  Publikacja

  • A. Malinowski
  • P. Czarnul

  - Scalable Computing: Practice and Experience - Rok 2018

  The paper presents a new approach to parallel image processing using byte addressable, non-volatile memory (NVRAM). We show that our custom built MPI I/O implementation of selected functions that use a distributed cache that incorporates NVRAMs located in cluster nodes can be used for efficient processing of large images. We demonstrate performance benefits of such a solution compared to a traditional implementation without NVRAM...

• Multi-agent large-scale parallel crowd simulation with NVRAM-based distributed cache

  Publikacja

  • A. Malinowski
  • P. Czarnul

  - Journal of Computational Science - Rok 2019

  This paper presents the architecture, main components and performance results for a parallel and modu-lar agent-based environment aimed at crowd simulation. The environment allows to simulate thousandsor more agents on maps of square kilometers or more, features a modular design and incorporates non-volatile RAM (NVRAM) with a fail-safe mode that can be activated to allow to continue computationsfrom a recently analyzed state in...

• Three levels of fail-safe mode in MPI I/O NVRAM distributed cache

  Publikacja

  • A. Malinowski
  • P. Czarnul

  - Procedia Computer Science - Rok 2018

  The paper presents architecture and design of three versions for fail-safe data storage in a distributed cache using NVRAM in cluster nodes. In the first one, cache consistency is assured through additional buffering write requests. The second one is based on additional write log managers running on different nodes. The third one benefits from synchronization with a Parallel File System (PFS) for saving data into a new file which...

  - Annals of Computer Science and Information Systems - Rok 2016

  While many scientific, large-scale applications are data-intensive, fast and efficient I/O operations have become of key importance for HPC environments. We propose an MPI I/O extension based on in-system distributed cache with data located in Non-volatile Random Access Memory (NVRAM) available in each cluster node. The presented architecture makes effective use of NVRAM properties such as persistence and byte-level access behind...
