• A model, design, and implementation of an efficient multithreaded workflow execution engine with data streaming, caching, and storage constraints

  Publikacja

  • P. Czarnul

  - JOURNAL OF SUPERCOMPUTING - Rok 2013

  The paper proposes a model, design, and implementation of an efficient multithreaded engine for execution of distributed service-based workflows with data streaming defined on a per task basis. The implementation takes into account capacity constraints of the servers on which services are installed and the workflow data footprint if needed. Furthermore, it also considers storage space of the workflow execution engine and its cost....

• Possibility to use engine compression ignition engines in floating power plants marine

  Publikacja

  • W. Olszewski

  - Rok 2012

  Compression-ignition engines used in ship technology as main propulsion engines are large units reaching even to 50-60 MW. The engines can be used in power industry for electricity generation in a simple or combined steam turbine system in combined heat and power plants. The leading engine in such an arrangement is an internal-combustion piston engine. The main propulsion engines are used in large piston internal-combustion engines...

  - Rok 2004

  Traditionally, log traces of test cases ex ecution are stored in textual format and their analysis is done in a post- execution phase. Our approach bases on the concept of gr aphical presentation of te st execution which enables better analysis of log traces and also gives the opportunity to consider them on-line. In particular, we discuss the graphical symbols we chose, we pres ent the logging interface we defined a nd describe...

• Modeling SPMD Application Execution Time

  Publikacja

  • J. Kuchta

  - Rok 2016

  Parallel applications in a Single Process Multiple Data paradigm assume splitting huge amounts of data to multiple processors working in parallel at small data packets. As the individual data packets are not independent, the processors must interact with each other to exchange results of the calculations with their adjacent partners and take these results into account in their own computations. An example of SPMD is geometric parallelism...

• Modeling DAC Application Execution Time

  Publikacja

  • J. Kuchta

  - Rok 2016

  An application written in the Divide And Conquer paradigm is more difficult to model than SPMD application because of complex algorithm, causing use of many coefficients in a computational complexity function. Processors are divided into various layers, each layer contains different number of processors. Data packets processed in different layers and transferred between layers have different length. Moreover first layer processors use...

• Performance and Emission Modelling and Simulation of Marine Diesel Engines using Publicly Available Engine Data

  Publikacja

  • M. H. Ghaemi

  - Polish Maritime Research - Rok 2021

  To analyse the behaviour of marine diesel engines in unsteady states for different purposes, for example to determine the fuel consumption or emissions level, to adjust the control strategy, to manage the maintenance, etc., a goal-based mathematical model that can be easily implemented for simulation is necessary. Such a model usually requires a wide range of operating data, measured on a test stand. This is a time-consuming process...

• Optimization of hybrid parallel application execution in heterogeneous high performance computing systems considering execution time and power consumption

  Publikacja

  • P. Rościszewski

  - Rok 2018

  Many important computational problems require utilization of high performance computing (HPC) systems that consist of multi-level structures combining higher and higher numbers of devices with various characteristics. Utilizing full power of such systems requires programming parallel applications that are hybrid in two meanings: they can utilize parallelism on multiple levels at the same time and combine together programming interfaces...

• Dynamic Compatibility Matching of Services for Distributed Workflow Execution

  Publikacja

  • P. Czarnul
  • M. Wójcik

  - Rok 2011

  The paper presents a concept and an implementation of dynamic learn-ing of compatibilities of services used in a workflow application. While services may have the same functionality, they may accept input and produce output in different formats. The proposed solution learns matching of outputs and inputs at runtime and uses this knowledge in subsequent runs of workflow applications. The presented solution was implemented in an...
