1. 11. Static Timing Analysis of Parallel Systems Using Abstract Execution

   Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; Nan Guan; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

   Sammanfattning : The Power Wall has stopped the past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism.Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. LÄS MER

3. 12. On Cyber-Security for In-Vehicle Software

   Författare :Aljoscha Lautenbach; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular Security; Memory Protection; Automotive Security; Memory Exploitation; In-Vehicle Network; Risk Assessment; CAN authentication; Secure Software Development;

   Sammanfattning : We live in a highly connected world, which brings many opportunities, but which also makes us vulnerable to attacks. Security in regular IT systems, such as desktop and server systems, has decades of active research behind it, whereas security in the automotive domain is still a relatively new topic. LÄS MER

4. 13. Accelerating Distributed Storage in Heterogeneous Settings

   Författare :Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []

   Sammanfattning : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. LÄS MER
