5) Deep Neural Networks for Malware Detection in Executables
As the use of computing devices increases in
every day life, malware detection continues to remain a serious challenge for corporations, governmental agencies,
and individuals. Today malware detection systems still heavily rely on heuristic and signature-based methods, where
signature represents set of rules that are generally specific and thus usually fail to capture a new malware. This
topic discusses an alternative approach, that uses neural networks and the raw bytes of the binary program itself to
determine maliciousness without executing the target application. Final technical report

currently one of the key technologies for managing and processing streams of data. The topic provides a general
overview of the system and describes the Kafka's key concepts (writing/reading data to/from Kafka). Final technical report
7) Streaming and batch processing with Apache Flink
According to a recent article from Forbes, around 90
percent of the data in the world today has been created in the last two years alone, and with the growth of Internet
of Things (IoT) devices this number is expected to increase further.The topic discusses Apache Flink, built as open
source software by an open community for distributed stream processing engineered to overcome certain tradeoffs that
have limited the effectiveness and/or ease-of-use of other approaches for processing streaming and batch data. Final technical report

deployed at Oak Ridge National Laboratory and recognized as the world's fastest computer back in June' 18 during
International Supercomputing Conference by delivering 122.3 PFLOPS performance during the LINPACK run. Since then
the system has been upgraded to deliver 143.5 PFLOPS LINPACK performance making it still the fastest supercomputer

10) Can less complex processors enable HPC?
Currently, there are three technology architectures evolving for
HPC: the first one is taking the commodity processors and putting them together with a high performance interconnect
to createa supercomputer. The second way to buildsuch a high-end system is to is to take the commodity processors
and augment them with accelerators (e.g. GPUs) that boost the delivered FLOP rate,i.e. performance of the system.

11) An empirical survey of performance and power variation of recent Intel processors
performance and energy/power efficiency analysis of homogeneous HPC systems (in terms of installed hardware and
system software stack) assumes homogeneity across performance and power characteristics of underlying system compute
