Performance Analysis for SVM-Fortran with OPAL

Programming distributed memory parallel computers with message passing is often considered to be a difficult task. To overcome the drawbacks of this programming style, several efforts have been made in the field of new parallel programming languages. One example is the shared virtual memory programming model. SVM-Fortran is an extension of Fortran77 for programming shared virtual memory systems. It provides special notations for work distribution to optimize data locality and load balance. There exists a number of different tools for performance debugging in message passing systems, but none of these would fulfill the special requirements of the SVM programming model. Moreover, we observed that the user requirements for performance debugging strongly recommend tools which are adapted to the programmers view of the program. Therefore, special emphasis is set on source code related methods of OPAL and the underlying trace generation with the performance monitor SAM

European international broadcasting and Islamist terrorism in Africa: The case of Boko Haram on <i>France 24</i> and <i>Deutsche Welle</i>

This article examines the relationship between European (international) broadcasting and Islamist terrorism in Africa and positions media portrayal of Boko Haram within the larger picture of Europe’s relations with Africa. Two international broadcasters provide the basis for the analysis: France 24 and Deutsche Welle. The article compares and contrasts their discourse on terrorism to advance several arguments: 1) that through their respective portrayal of Boko Haram and Nigeria both France 24 and Deutsche Welle’s reporting is in line with their respective countries’ foreign policies towards Africa, 2) that discourse on both F24 and DW perpetuates the unequal relationship between African countries and Western powers, 3) that portraying terrorism in terms of ‘clash of civilisations’, as in the case of France 24, may unintentionally contribute to the strengthening of the extremist cause. This is due to the transformation of violent extremism into ‘new wars’. The concept, elaborated in the article, differently explains the logic of extremist behaviour and its relationship with media
