  - Scalable Computing: Practice and Experience - Year 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...

  - Procedia Computer Science - Year 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...

  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...

  - Year 2019

  Obecnie wiele badań podejmuje temat rosnącego problemu wydajności operacji na plikach w środowiskach klastrowych. Jednocześnie, według ostatnich doniesień związanych z rozwojem technologii pamięci komputerowych, w najbliższej przyszłości na rynku powinny pojawić się układy trwałej pamięci o dostępie swobodnym, adresowanej bajtowo. Niniejsza rozprawa pokazuje, że przy użyciu takiej pamięci można zwiększyć wydajność wybranych...

  - ACTA CRYSTALLOGRAPHICA SECTION E-STRUCTURE REPORTS ONLINE - Year 2011

  In the title compound, NH4+·(C2H5O)2PS2−, the ammonium cation is connected by four charge-assisted N−H···S hydrogen bonds to four tetrahedral O,O'-diethyl dithiophosphate anions, forming layers parallel to (100). The polar and non-polar constituents of the layers are stacked alternately along [100]. Interlacing of the external ethyl groups...
