Efficient Search Space Exploration for HW-SW Partitioning
No full textHardware/software (HW-SW) partitioning is a key problem in the codesign of embedded systems, studied extensively in the past. One major open challenge for traditional partitioning approaches -- as we move to more complex and heterogeneous SOCs -- is the lack of efficient exploration of the large space of possible HW/SW configurations, coupled with the inability to efficiently scale up with larger problem sizes. In this paper, we make two contributions for HW-SW partitioning of applications represented as procedural callgraphs: 1) we prove that during partitioning, the execution time metric for moving a vertex needs to be updated only for the immediate neighbours of the vertex, rather than for all ancestors along paths to the root vertex; consequently, we observe faster run-times for move-based partitioning algorithms such as Simulated Annealing (SA), allowing call graphs with thousands of vertices to be processed in less than a second, and 2) we devise a new cost function for SA that allows frequent discovery of better partitioning solutions by searching spaces overlooked by traditional SA cost functions. We present experimental results on a very large design space, where several thousand configurations are explored in minutes as compared to several hours or days using a traditional SA formulation. Furthermore, our approach is frequently able to locate better design points with over 10 % improvement in application execution time compared to the solutions generated by a Kernighan-Lin partitioning algorithm starting with an all-SW partitioning
Very fast simulated annealing for HW-SW partitioning
No full textHardware/software (HW-SW) partitioning is a key problem in the codesign of embedded systems and has been studied extensively in the past. With the wide availability of commercial platforms such as the Virtex-II Pro series from Xilinx that integrate processors with reconfigurable logic, one major existing challenge is the lack of efficient algorithms that can generate very high-quality solutions by exploring a huge HW/SW exploration space- the key criterion is to obtain such solutions at a speed suitable for integration into a compiler-based partitioner. In this report, we make two contributions for HW-SW partitioning of applications specified as procedural call-graphs: 1) We prove that during partitioning, the execution time metric for moving a vertex needs to be updated only for the immediate neighbours of the vertex, rather than for all ancestors along paths to the root vertex. This enables move-based partitioning algorithms such as Simulated Annealing (SA) to execute significantly faster, allowing call graphs with thousands of vertices to be processed in less than half a second 2) Additionally, we devise a new cost function for SA that enables searching of spaces overlooked by traditional SA cost functions for HW-SW partitioning, allowing the discovery of additional partitionin
Dependence of unsaturated chloride diffusion on the pore structure in cementitious materials
No full textConceptual analysis is performed to examine the effects of pore features on the water continuity in unsaturated porous systems. The roles of pore features in relative chloride diffusion coefficient (Drc) of mortar specimens at various degrees of water saturation (Sw) were studied based on mercury intrusion porosimetry and resistivity tests. It is found that the role of pore structure in the Drc-Sw relationship is a result of its effect on the water continuity. Porosity and tortuosity are not relevant to the Drc-Sw relationship. A finer pore size distribution or lower pore connectivity tends to result in a lower Drc. The pore size effect on the Drc is pronounced primarily at high Sw, while the Drc is dominated by the pore connectivity at low Sw. Cement mortar with a higher water-to-binder ratio shows larger chloride diffusion at high relative humidity levels but smaller chloride diffusion at low relative humidity levels.Accepted Author ManuscriptMaterials and Environmen
Total Cost of Ownership for Application Replatform by Open-source SW
No full textAbstractIn intra-company IT environment, the use of open-source software (OSS) should be expanded to reduce IT costs and to establish SW governance. This requires the migration of systems from the existing commercial SW to open-source SW, but the attempt of application replatform is prevented by the expenses for application reprogramming and data migration. This study proposes a methodology for TCO calculation of application replatform using open-source SW. In practice, a five-year TCO shows a cost reduction effect of 78% - 83%. This TCO could be further reduced if the application size is increased due to data accumulation and the company gets open-source SW capabilities internally. In addition, it is possible to directly apply an application developed from open-source SW to a virtualized infrastructure environment, which enables to operate in a hybrid cloud environment. This enables a scalable, efficient and flexible IT operation and a sustainable TCO reduction in the futur

Change management of the SW projects in the small and medium business
No full textThe bachelor thesis focuses on SW projects, ways of their management and mainly change management in the small and medium business. This thesis is devided into two parts. Author deals with SW projects and most common mistakes during their development in the theory part. The main aim of this part is to refer to these mistakes the reader, who is interested in SW projects. Next, there is a comparision of the two famous methodics, which are well-known in the SW development. These are ITIL and RUP. Author will choose the one, which will be more acceptable for the Cleverdecision. At this time, Cleverdecision has no change management and every change during the SW development is managed by contracting condition. That is why author formulates the ways of change management in the practical part. This will be based on the chosen methodics from the theory part. This formulation is the main aim of this thesis. The contribution of the thesis is in the definition of the change management workflow and in the proposition of the templates for setting the change requests. These templates are sufficient for unification concepts and easier specification of the change requests. Insertion of the change management into the contract is part of the thesis as well
