1. 1. Workload characterization, controller design and performance evaluation for cloud capacity autoscaling

   Författare :Ahmed Ali-Eldin Hassan; Erik Elmroth; Johan Tordsson; Prashant Shenoy; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; autoscaling; workloads; performance modeling; controller design;

   Sammanfattning : This thesis studies cloud capacity auto-scaling, or how to provision and release re-sources to a service running in the cloud based on its actual demand using an auto-matic controller. As the performance of server systems depends on the system design,the system implementation, and the workloads the system is subjected to, we focuson these aspects with respect to designing auto-scaling algorithms.

3. 2. HPC scheduling in a brave new world

   Författare :Rodrigo Gonzalo P.; Erik Elmroth; Lavanya Ramakrishnan; Per-Olov Östberg; Ewa Deelman; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High Performance Computing; HPC; supercomputing; scheduling; workflows; workloads; exascale; business data processing; administrativ databehandling;

   Sammanfattning : Many breakthroughs in scientific and industrial research are supported by simulations and calculations performed on high performance computing (HPC) systems. These systems typically consist of uniform, largely parallel compute resources and high bandwidth concurrent file systems interconnected by low latency synchronous networks. LÄS MER

4. 3. Cache memory design trade-offs for current and emerging workloads

   Författare :Martin Karlsson; Erik Hagersten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

   Sammanfattning : The memory system is the key to performance in contemporary computer systems. When designing a new memory system, architectural decisions are often arbitrated based on their expected performance effect. It is therefore very important to make performance estimates based on workloads that accurately reflect the future use of the system. LÄS MER

5. 4. Industrial development of car disassembly - ergonomics and system performance

   Författare :Karolina Kazmierczak; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physical workloads; production systems; muskelsystem; reumatologi; rheumatology locomotion; Skelett; muscle system; Skeleton; flow and human simulations; video-task analysis; rationalizations; car disassembly; musculoskeletal disorders; Technological sciences; Teknik;

   Sammanfattning : A new EU directive on used vehicles has recently been introduced. It demands that for every scrapped car, at least 85% by weight must be recycled by the year 2006 and 95% by 2015. The current level is about 80%. The car disassembly industry was chosen as the study object of this thesis. LÄS MER

7. 5. Large-scale I/O Models for Traditional and Emerging HPC Workloads on Next-Generation HPC Storage Systems

   Författare :Wei Der Chien; Stefano Markidis; Erwin Laure; Artur Podobas; Philip Carns; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HPC; I O; Parallel I O; MPI; object storage; TensorFlow; Data-Centric; Artificial Intelligence; Machine Learning; Computer Science; Datalogi;

   Sammanfattning : The ability to create value from large-scale data is now an essential part of research and driving technological development everywhere from everyday technology to life-saving medical applications. In almost all scientific fields that require handling large-scale data, such as weather forecast, physics simulation, and computational biology, supercomputers (HPC systems) have emerged as an essential tool for implementing and solving problems.
