Winter wheat is threatened by drought in the Huang-Huai-Hai Plain of China, thus, effective water-saving irrigation practices are urgently required to maintain its high winter wheat production. This study was conducted from 2012 to 2014 to determine how supplemental irrigation (SI) affected soil moisture, photosynthesis, and dry matter (DM) production of winter wheat by measuring the moisture i...

Coarse-grained reconfigurable architectures (CGRAs) are capable of achieving both goals of high performance and flexibility. CGRAs not only improve performance by exploiting the features of repetitive computations, but also can adapt to diverse computations by dynamically changing configurations of an array of its internal processing elements (PEs) and their interconnections. Many CGRAs have be...

LPARX is a software development tool for implementing dynamic, irregular scientiic applications , such as multilevel multilevel nite diierence methods and particle methods, on high performance MIMD parallel architectures. It supports coarse grain data parallelism and gives the application complete control over specifying arbitrary block decompositions. LPARX provides structural abstraction, rep...

Reconfigurable systems, and in particular, FPGA-based custom computing machines, offer a unique opportunity to define application-specific architectures. These architectures offer performance advantages for application domains such as image processing, where the use of customized pipelines exploits the inherent coarse-grain parallelism. In this paper we describe a set of program analyses and an...

It has been shown recently that it is possible to eeciently schedule direct acyclic task graphs. A tool like Pyrros 14] is able to generate a parallel program, if the user speciies precedence constraints between the tasks. This approach has two major drawbacks: it is hard for the user to perform a good analysis of the source code and scheduling a DAG is costly in terms of memory and time. In 3]...

We consider the problem of optimizing select-project-join relational queries for minimum response time on parallel machines. The design of the optimizer is based on three ideas: (1) the concept and quanti cation of degree of coarse grain parallelism for an execution tree, (2) the design of a parallelizing scheduler for a tree of coarse grain operations which is provably near optimal, and (3) th...

Here, we review recent advances towards the modelling of protein-protein interactions (PPI) at the coarse-grained (CG) level, a technique that is now widely used to understand protein affinity, aggregation and self-assembly behaviour. PPI models of soluble proteins and membrane proteins are separately described, but we note the parallel development that is present in both research fields with t...

Performance evaluation tools enable analysts to shed light on how applications behave both from a general point of view and at concrete execution points, but cannot provide detailed information beyond the monitored regions of code. Having the ability to determine when and which data has to be collected is crucial for a successful analysis. This is particularly true for trace-based tools, which ...

Many embedded systems require hard or soft real-time execution. To ensure the requirements are met, it is necessary to measure the execution time of individual tasks, as well as establish the overall real-time performance of the system. This paper presents a variety of techniques, at both coarse-grain and fine-grain levels, to measure execution time of both user code and operating system overhe...
