Man the Slave and Master

������������������������� � Master-Slave ������

近些年来,随着计算机的计算能力和存储能力的飞速发展,科学计算的规模越来越大,在气象、生物技术、 油藏模拟、核技术等领域,用于计算的网格已达到百万、千万乃至数十亿,计算的数据结果也已达到 GB 乃至 TB 大小。而和计算、存储技术的飞速发展相比,由于受材料、电子等工艺的限制,计算机的显示尺寸的发展相对滞 后。如何能够快速、准确的表现海量数据已经成为一个亟需解决的问题。它不仅包括如何以更大的屏幕来显示数 据,还包括如何以更快的速度来处理数据。 使用并行计算技术的大屏幕显示是解决上述问题一个很好的途径。采用多个显示设备取代原来的单个显示设 备使得显示屏幕增大为相应的倍数;各个显示设备由单独的计算机进行驱动,计算任务的分担使得显示速度也大 大提高。 除了在科学计算方面的应用外,大屏幕显示作为一种“半沉浸式”的虚拟环境,在虚拟战场、视频会议、公 共场合演示等方面也有着广泛的应用。 大屏幕显示技...

Master-slave synchronization and the Lorenz equations.

Since the seminal remark by Pecora and Carroll [Phys. Rev. Lett. 64, 821 (1990)] that one can synchronize chaotic systems, the main example in the related literature has been the Lorenz equations. Yet this literature contains a mixture of true and false, and of justified and unsubstantiated claims about the synchronization properties of the Lorenz equations. In this note we clarify some of the ...

"Master-Slave" Biological Network Alignment

Performing global alignment between protein-protein interaction (PPI) networks of different organisms is important to infer knowledge about conservation across species. Known methods that perform this task operate symmetrically, that is to say, they do not assign a distinct role to the input PPI networks. However, in most cases, the input networks are indeed distinguishable on the basis of how ...

Master/Slave Computing on the Grid

Resource selection is fundamental to the performance of master/slave applications. In this paper, we address the problem of promoting performance for distributed master/slave applications targeted to distributed, heterogeneous ”Grid” resources. We present a work-rate-based model of master/slave application performance which utilizes both system and application characteristics to select potentia...
