Taming the Raven - Testing the Random Access, Visualization and Exploration Network RAVEN
نویسنده
چکیده
The Random Access, Visualization and Exploration Network (RAVEN) aims to allow for the storage, analysis and visualisation of peta-bytes of scientific data in (near) real-time. In essence, RAVEN is a huge distributed and parallel system. While testing of distributed systems, such as huge telecommunication systems, is well understood and performed systematically, testing of parallel systems, in particular high-performance computing, is currently lagging behind and is mainly based on ad-hoc approaches. This paper surveys the state of the art of software testing and investigates challenges of testing a distributed and parallel high-performance RAVEN system. While using the standardised Testing and Test Control Notation (TTCN-3) looks promising for testing networking and communication aspects of RAVEN, testing the visualisation and analysis aspects of RAVEN may open new frontiers.

RAVEN - Boosting Data Analysis for the LHC Experiments
The analysis and visualization of the LHC data is a good example of human interaction with petabytes of inhomogeneous data. After outlining the computational requirements for an efficient analysis of such data sets, a proposal, RAVEN – a Random Access, Visualization and Exploration Network for petabyte sized data sets, for a scalable architecture meeting these demands is presented. The proposed...
متن کاملResearch environment for developing and testing object tracking algorithms
We present an integrated research environment (RAVEN) that we have developed for the purpose of developing and testing object tracking algorithms. As a Windows application, RAVEN provides a user interface for loading and viewing video sequences and interacting with the segmentation and object tracking algorithms, which are included at run time as plug-ins. The plug-ins interact with RAVEN via a...
متن کاملAdaptive Flight Control Experiments using RAVEN
This paper discusses a new flight test facility at MIT known as the Real-time indoor Autonomous Vehicle test ENvironment (RAVEN) which enables the exploration of aggressive aerobatic flight with relatively low risk. A key feature of this work is that the control algorithms are often the limiting factor because the flight dynamics are highly nonlinear and not well known, and they can change with...
متن کاملControlling Concurrent Access to Objects in the Raven System
This paper presents the rationale and design of the concurrency control features of Raven, an object-oriented distributed and parallel programming language and system. Raven's parallel constructs support coarse grained parallelism and are designed to permit programmers to use parallelism with relative ease. To achieve this Raven provides automatic concurrency control on an object's instance dat...
