16. Accelerating Distributed Storage in Heterogeneous Settings
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
17. Reducing Memory Traffic with Approximate Compression
Sammanfattning : Memory bandwidth is a critical resource in modern systems and has an increasing demand. The large number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates. In addition, new emerging data-intensive applications further increase memory traffic. LÄS MER
18. Falsification of Signal-Based Specifications for Cyber-Physical Systems
Sammanfattning : In the development of software for modern Cyber-Physical Systems, testing is an integral part that is rightfully given a lot of attention. Testing is done on many different abstraction levels, and especially for large-scale industrial systems, it can be difficult to know when the testing should conclude and the software can be considered correct enough for making its way into production.

19. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing
Sammanfattning : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.

20. High Performance Hybrid Memory Systems with 3D-stacked DRAM
Sammanfattning : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. LÄS MER
