Opis:
Grid computing has recently gained in popularity. Grid applications can be very demanding of the data storage facilities in the Grid. The existing data grid services are often insufficient and additional optimization of the data access is necessary. This paper presents research concerning the optimization aspects of data management for Hierarchical Storage Management (HSM) systems in the Grid.

Opis:
In this paper we present the design of a Grid HLA Management System (GHMS) supporting execution of High Level Architecture-based interactive applications in a Grid environment, while at the same time allowing for running HLA legacy codes to preserve backward compatibility with the HLA standard. In particular, we describe the following system components: an HLA-Speaking Service for multiple federates that interface the HLA application to the system, a Monitoring Service integrated with the OCMG monitoring system and HLA-based Benchmark Services informing the Broker Service of what can be expected from the application's behavior.

Opis:
The CrossGrid Project aims to develop new Grid services and a tool environment for a representative set of interactive compute- and data-intensive applications. This paper presents the architecture of the software and a description of the functionality of the main components. The new tools and grid services are based on the Globus Toolkit and the EU DataGrid middleware. CrossGrid develops and operates a large international testbed, where the developed applications, services and tools are deployed and run.

Opis:
This paper summarizes research on monitoring GRID resources, which resulted in the implementation of the JIMS system. It contains an overview of the most important architectural and software concepts that make the constructed system flexible and user-friendly. The paper evaluates JMX and Web Service technologies as foundations for implementing monitoring systems. Particular attention has been paid to system adaptability, autoconfiguration and interoperability.

Tematy:
Navier-Stokes equation
artificial compressibility

two grids method
Opis:
An artificial compressibility method is designed to simulate stationary two-and threedimensional motions of a viscous incompressible fluid. A standard method of lines approach is applied in this contribution. A partial differential equation system is discretized in space by secondorder finite-difference schemes on uniform computational grids, and the time-variable is preserved as continuous. Initial value problems for systems of ordinary differential equations for pressure and velocity components are computed using the Galerkin-Runge-Kutta method of third order. Some test calculations for laminar flows in square, cubic, triangular and semicircular cavities with one uniform moving wall and double bent channels are reported.

Tematy:
Navier-Stokes equation
velocity correction method

two grids method
Opis:
The velocity correction method is designed to simulate stationary and non-stationary, two- and three-dimensional motions of a viscous incompressible fluid. The basic assumption of this method consists in splitting the velocity and the pressure fields and calculations are performed in two steps. In the first step, a tentative velocity field is determined by simplified equations for momentum conservation. In the second step the Neumann problem for the Poisson equations is solved to obtain the computational pressure, and the velocity components are corrected. A standard method of lines approach and the two grids method are applied in this contribution. Some test calculations for laminar and transitional flows in square and cubic cavities with one moving wall as well as in a backward-facing step are reported.
