The calculation of small-scale data is commonly used in scientific computing and application domain, and the high-efficiency method of small calculation can give play to the potency of many calculation and application. In this paper, a novel self-adaptive parallel computing method based on the graphics processing unit (GPU) architecture for batches of small scale computing tasks is proposed herein...
Recently, there is growing interest in directly digitizing the scintillation pulses in PET detectors. With digital pulse samples, in principle one can apply nontrivial signal analysis software algorithms to either yield better detection performance or more flexibility in detector design. Previously, we have proposed the MVT method for direct scintillation pulse sampling and developed several kinds...
Hypervisor-based fault tolerance (HBFT), which synchronizes the state between the primary VM and the backup VM at a high frequency of tens to hundreds of milliseconds, is an emerging approach to sustaining mission-critical applications. Based on virtualization technology, HBFT provides an economic and transparent fault tolerant solution. However, the advantages currently come at the cost of substantial...
The quality of service oriented architecture (SOA) solutions is becoming more and more important along with the increasing adoption of SOA. Continuous integration testing (CIT) is an effective technology to discover bugs as early as possible. However, the diversity of programming models used in an SOA solution and the distribution nature of an SOA solution pose new challenges for CIT. Existing testing...
We propose a novel design estimation method for adaptive streaming applications to be implemented on a partially reconfigurable FPGA. Based on experimental results we enable accurate design cost estimates at an early design stage. Given the size and computation time of a set of configurations, which can be derived through logic synthesis, our method gives estimates for configuration parameters, such...
Role is an important concept in collaboration systems and CSCW systems especially in the aspect of group awareness. This paper proposes a new group awareness model based on role by the research of role in collaboration systems and the analysis of existing awareness models. In the new proposed model, the task is decomposed into activities in order to acquire the activity graph. Then the roles are extracted...
We address the problem of real-time streaming applications scheduling on hybrid CPU/FPGA architectures. The main contribution is a two-step approach to minimize the buffer requirement for streaming applications with throughput guarantees. A novel declarative way of constraint based scheduling for real-time hybrid SW/HW systems is proposed, while the application throughput is guaranteed by periodic...
Software production line can be created by integrated framework which can integrate software tools, software components, software services, and collaboration mechanism. It can be used as one of the important software reuse techniques. This paper provides the definitions and differentiations of software product line, software production line and plugin architecture. A platform independent model of...
