    Experiences with the Model-based Generation of Big Data Pipelines
    (Datenbanksysteme für Business, Technologie und Web (BTW 2017) - Workshopband, 2017) Eichelberger, Holger; Qin, Cui; Schmid, Klaus
    Developing Big Data applications implies a lot of schematic or complex structural tasks, which can easily lead to implementation errors and incorrect analysis results. In this paper, we present a model-based approach that supports the automatic generation of code to handle these repetitive tasks, enabling data engineers to focus on the functional aspects without being distracted by technical issues. In order to identify a solution, we analyzed different Big Data stream-processing frameworks, extracted a common graph-based model for Big Data streaming applications and de- veloped a tool to graphically design and generate such applications in a model-based fashion (in this work for Apache Storm). Here, we discuss the concepts of the approach, the tooling and, in particular, experiences with the approach based on feedback of our partners.

    Extending a Compiler Backend for Complete Memory Error Detection
    (Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Rink, Norman; Castrillon, Jeronimo
    Technological advances drive hardware to ever smaller feature sizes, causing devices to become more vulnerable to faults. Applications can be protected against errors resulting from faults by adding error detection and recovery measures in software. This is popularly achieved by apply- ing automatic program transformations. However, transformations applied to intermediate program representations are fundamentally incapable of protecting against vulnerabilities that are introduced during compilation. In particular, the compiler backend may introduce additional memory accesses. This report presents an extended compiler backend that protects these accesses against faults in the memory system. It is demonstrated that this enables the detection of all single bit flips in memory. On a subset of SPEC CINT2006 the runtime overhead caused by the extended backend amounts to 1.50x for the 32-bit processor architecture i386, and 1.13x for the 64-bit architecture x86 64.
