To compare the newly determined sequences against the subject sequences stored in the databases is a critical job in the bioinformatics. Fortunately, recent survey reports that the state-of-the-art aligners are already fast enough to handle the ultra amount of short sequence reads in the reasonable time. However, for aligning the long sequence reads (> 400bp) generated by the next generation sequencing...
This paper proposes a framework targeting the problem of task-level out-of-order (OoO) execution for heterogeneous systems. The framework consists of three layers: 1) Programming model; 2) OoO task scheduler; 3) Processing Elements. In order to uncover task-level parallelism automatically, renaming scheme is applied from instruction-level parallelism (ILP) to task-level parallelism (TLP). With the...
This paper proposes a flexible programming model (FPM), which addresses the automatic parallel execution for functional tasks on heterogeneous multiprocessors. Guided by the simply annotated source codes, a front-end source to source compiler is provided to identify the parallel regions and generate the sources codes. A runtime middleware analyzes the inter-task data dependencies and schedules the...
Multi-Processor System on Chip (MPSoC) platform plays a vital role in parallel processor architecture design. However, it poses a great challenge to design a flexible high-speed network regarding as the growing number of processors. This paper proposes a star network based on peer to peer links on FPGA. The stat network uses fast simplex links (FSL) for demonstration to connect scheduler and processing...
The remarkable and continuous increase in link speed and application variety of Internet calls for new QoS provision technology that is both efficient and flexible. Being a kind of application-specific processor optimized for network computation, network processor (NP) combines the high performance of hardware and the flexibility of software, which exactly meets the demands of nowadays Internet traffic...
