Laboratory of Parallel and Distributed Systems

The Laboratory of Parallel and Distributed Systems (LPDS), as a department of MTA SZTAKI, is a research laboratory in distributed grid and cloud technologies. LPDS is a founding member of the Hungarian Grid Competence Centre, the Hungarian National Grid Initiative and the Hungarian OpenNebula Community and also coordinates several European grid/cloud projects. The mission of LPDS is twofold. On one hand we would like to provide efficient software development tools and high-level services together with customizable scientific gateways. On the other hand LPDS is developing easy-to-maintain middleware solutions and technologies for interoperability that enables cost-efficient alternative distributed, grid and cloud platforms for scientific and business applications. LPDS laboratory, in cooperation with other departments of MTA SZTAKI, was involved in the development of the SZTAKI Cloud, and takes part in more and more cloud-based projects. The LPDS cloud research is focusing on the field of Infrastructure as a Service (IaaS)-based cloud systems to make the previously evolved products and services of LPDS to be available for cloud-based executing in a scalable and transparent way.

Main products and services
gUSE (grid and cloud User Support Environment) is a well-known and permanently improving open source science gateway framework that enables users the convenient and easy access to grid and cloud infrastructures. It has been developed to support a large variety of user communities. It provides a general purpose, workflow-oriented graphical user interface to create and run workflows on various Distributed Computing Infrastructures including clusters, grids, desktop grids and clouds. The gUSE framework can be used by National Grid Initiatives (NGIs) to support small user communities who cannot afford to develop their own customized science gateway.
Public WS-PGRADE Portal (a public installation of WS-PGRADE/gUSE) is a Liferay technology-based web portal of gUSE. It can be accessed via the major modern web browsers like Chrome, Firefox, etc. It supports development and submission of distributed applications executed on the computational resources of various distributed computing infrastructures (DCIs) including clusters, service grids, desktop grids and clouds.
Data Avenue is a file commander tool for data transfer, enabling easy data moving between various storage services over various network protocols. Data Avenue is integrated into WS-PGRADE as a portlet.
The goal of SZTAKI Cloud was to develop and to deploy an institutional cloud infrastructure that allows the significant improvement of the traditional institutional IT infrastructure. This new cloud-based infrastructure is significantly more effective and more cost efficient than the former infrastructure built on traditional conceptions and individual specific servers.
SZTAKI Desktop Grid provides an enterprise solution to exploit PCs and clusters located at different sites of a company or institute, solving large scale distributed programs via an easy-to-use application programming interface. It is extended to include clusters as single powerful PCs and to hierarchically propagate work from one desktop grid to the other.
LPDS also participates in Big Data management and storage within the field of agricultural research.
