چکیده

We present load-balancing strategies to improve the performances of parallel MPI applications running in a Grid environment. We analyze the data distribution constraints found in two scientific codes and propose adapted code transformations to load-balance computations. Experimental results confirm that such source code transformations can improve Grid application performances.

Design of the new multilevel current source converter to grid connected applications

A novel current source multilevel inverter is introduced in this paper which is an appropriate alternative to be employed for low/medium power applications. the proposed converter is formed basic modules which paralleling these modules increse output current levels and improve quality of injected current to load or grid. in order to validate advantages of proposed converter versus the several m...

Grid Integration of a Single-Source Switched-Capacitor Multilevel Inverter with Boosting Capability

This paper investigates the connection of a single-phase multilevel inverter structure to an existing power grid. The applied voltage source inverter is able to generate a near sinusoidal voltage waveform with an amplitude six times the input voltage by using a single DC input power supply. A proportional-resonant (PR) controller regulates the injected current into the grid. While the EPLL is u...

Using the ASM framework to implement common Java bytecode transformation patterns

Most AOP frameworks targeting the Java platform use a bytecode weaving approach as it is currently considered the most practical solution. It allows applying cross-cutting concerns to Java applications when source code is not available, is portable and works on existing JVMs, in comparison to VM-level AOP implementations. Load-time bytecode weaving (LTW), which happens right before the applicat...

Graduate Project Proposal: (Alternative) Implementation Strategies for Island Parsers

The Software Improvement Group (SIG) offers specialized services that helps companies gaining insight in their legacy code bases. To this end, the internal design structure of a code base is captured by the SIG in a so called source model. A source model can be used, for example, to estimate the amount of work needed for future modifications or to report on various software metrics of the code ...

Weighted-HR: An Improved Hierarchical Grid Resource Discovery

Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. In these environments, the required resources must be accessible for Grid applications on demand, which makes the resource discovery as a critical service. In recent years, various techniques are proposed to index and discover the Grid resource...
