~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Today, I will introduce an open cloud computing testbed: OpenCirrus. I found this testbed just the day before yesterday when I was wondering waht to talk today. I don’t know about this platform entirely, but it’s so similar with PlanetLab. I wonder if we can use it for some potential experiments on cloud computing. So I show it to you here.

OpenCirrus was first established in 2008, and provides a single testbed of heterogeneous distributed data centers, for systems, applications and services research. This note is the presentation for OpenCirrus Summit by managing director at HP last year.

This is the outline of this talk, mainly including some general information about OpenCirrus, and also some recent research examples.

The OpenCirrus is established and sponsored by HP, Intel and Yahoo! with additional support form NSF. It aims to spur innovation in systems and applications research. Some interesting datasets may also be collected for sharing. It mainly provides global services about signing on, monitoring, and store. OpenCirrus currently has 15 sites all over the world and more than 100 nodes for each site. This is the distribution map of the sites, mainly including some universities, such as CMU and companies like HP, Intel and Yahoo!. China Mobile and China Telecom also join to this testbed system.

The OpenCirrus has several objectives. The most important one is to foster systems research around cloud computing. And also expose research community to enterprise level requirements. OpenCirrus is a kind of federation of heterogeneous datacenters, to support your research and data sets collection.

This page shows the governance model for OpenCirrus. Each site runs its own research and technical teams, just similar to PlanetLab.

This is the snapshot of the website of OpenCirrus. You can request access to the OpenCirrus here. Different with PlanetLab, you can apply for access to OpenCirrus even if you are not a member of this system.

Here is the Cirrus cluster topology at HP labs. We can find that there are 256 nodes containing 1024 cores, 3328GB (giga) for RAM and 632TB (tera) for storage, all connected by 1Gb/s or 10Gb/s high bandwidth link.

Intel research cluster also has 155 nodes in its data center. 

UIUC cluster also has many compute nodes and storage nodes with high performance link.

This is the detailed information for some sites, about the # of cores, servers, memory size, storage size, network bandwidth and research focus for each site.

Each access should be based on the ssh gateway for security. But web services are also supported on port 80 or 443.

The OpenCirrus software stack contains may layers, say, IT infrastructure layer, cloud infrastructure services, virtual resource sets and application services. The PRS service, Tashi and Hadoop is ongoing projects of HP. 

But how can we get access to OpenCirrus sites? The Project primal investigator should apply to each site separately. We can have their emails on their website. Users are able to login to each site with the same username and password. 

The OpenCirrus is seeking research in these areas, including datacenter federation, datacenter management, web services, data-intensive applications and systems, Hadoop map-reduce applications.

We can see its success form the growing number of sites, developers and users. 

There are many testbeds for research, such as IBM/Google cluster, TeraGrid, PlanetLab, EmuLab. This is a comparison between them. For example, EmuLab is for network emulation and PlanetLab is for system and networking research. In addition, the distribution scale and participants are different.

Here are lists of research projects with OpenCirrus of HP and Intel, such as Wikipedia mining & tagging at application level, Tashi at infrasture service level and OpenNet at infrastructure level. OpenCirrus is a programmable open layer-2 network. It has been installed on OpenCirrus cluster at HP.

GENI is Global Environment for Network Innovations. OpenCirrus has been accepted to be a GENI project.

Next, here lists some research examples related to OpenCirrus. Sparql query over hadoop for very large RDF datasets, N-tier application benchmark and evaluation over Open Cirrus. 

Next is the cloud sustainability dashboard. We can see that the cost in this table, when the price is low, the average entry is green, otherwise, it’s red. The objective is to express and display run-time sustainability of cloud and cloud services.

Here we can get some successful experience on OpenCirrus. For example, he said our NSDI paper would not have happed without Open Cirrus.

Finally is the summary, the OpenCirrus is growing and has enabled a lot of research. Also OpenCirrus summits have been hold for 6 times. 

Thank you!


本课题设计了一种利用Matlab平台开发的植物叶片健康状态识别方案,重点融合了色彩与纹理双重特征以实现对叶片病害的自动化判别。该系统构建了直观的图形操作界面,便于用户提交叶片影像并快速获得分析结论。Matlab作为具备高效数值计算与数据处理能力的工具,在图像分析与模式分类领域应用广泛,本项目正是借助其功能解决农业病害监测的实际问题。 在色彩特征分析方面,叶片影像的颜色分布常与其生理状态密切相关。通常,健康的叶片呈现绿色,而出现黄化、褐变等异常色彩往往指示病害或虫害的发生。Matlab提供了一系列图像处理函数,例如可通过色彩空间转换与直方图统计来量化颜色属性。通过计算各颜色通道的统计参数(如均值、标准差及主成分等),能够提取具有判别力的色彩特征,从而为不同病害类别的区分提供依据。 纹理特征则用于描述叶片表面的微观结构与形态变化,如病斑、皱缩或裂纹等。Matlab中的灰度共生矩阵计算函数可用于提取对比度、均匀性、相关性等纹理指标。此外,局部二值模式与Gabor滤波等方法也能从多尺度刻画纹理细节,进一步增强病害识别的鲁棒性。 系统的人机交互界面基于Matlab的图形用户界面开发环境实现。用户可通过该界面上传待检图像,系统将自动执行图像预处理、特征抽取与分类判断。采用的分类模型包括支持向量机、决策树等机器学习方法,通过对已标注样本的训练,模型能够依据新图像的特征向量预测其所属的病害类别。 此类课题设计有助于深化对Matlab编程、图像处理技术与模式识别原理的理解。通过完整实现从特征提取到分类决策的流程,学生能够将理论知识与实际应用相结合,提升解决复杂工程问题的能力。总体而言,该叶片病害检测系统涵盖了图像分析、特征融合、分类算法及界面开发等多个技术环节,为学习与掌握基于Matlab的智能检测技术提供了综合性实践案例。 资源来源于网络分享,仅用于学习交流使用,请勿用于商业,如有侵权请联系我删除!
