Extensible Terascale Facility (ETF): Indiana-Purdue Grid (IP-grid)

印第安纳大学与普渡大学合作，由高级计算基础设施部签署的一项为期两年的合作协议资助1,517,430美元，将印第安纳大学和普渡大学现有的资源与可扩展Terascale设施(ETF)整合在一起。为建立从印第安纳大学和普渡大学通过印第安纳波利斯到ETF芝加哥枢纽的20 Gb/秒连接提供资金，印第安纳大学和普渡大学将向ETF用户社区贡献其资源的一大部分，包括：1)一组持续提供1.67万亿次浮点运算的异类系统，能够为非常苛刻的合理应用程序提供高达6.26万亿次浮点运算；2)作为ETF的一部分提供的基准存储容量将包括129万亿字节，峰值需求贡献超过400万亿字节；3)还提供各种可视化资源，包括洞穴、沉浸式望远镜、展示墙等；4)专门的仪器设施，包括普渡地球天文台和先进光子源(废料)的服务结晶学；以及5)访问生命科学、地球系统模拟、植被和土壤研究、多光谱遥感成像、地质地理信息系统数据、经济和社会科学数据以及人类学数据中的一些大型科学数据集。印第安纳大学和普渡大学的研究人员也将为可扩展Terascale设施的更广泛目标做出重大贡献。他们在网格计算、中间件和门户开发领域拥有相当多的专业知识。这两所大学通过其IP网格的参与，还开展了广泛的外联活动，促进从K-12课程到本科生和研究生课程的多样化技术劳动力的培训和教育。

Indiana University, in collaboration with Purdue University is funded by a two-year Cooperative Agreement from the Division of Advanced Computational Infrastructure in the amount of $1,517,430 to integrate the resources available at Indiana University and Purdue University with the Extensible Terascale Facility (ETF). Funding is provided to establish a 20 gigabit/second connection from Indiana University and Purdue University through Indianapolis to the Chicago Hub of the ETF.As a result of the funding provided through this Terascale Extension Award, Indiana University and Purdue University will be contributing a significant fraction of their resources to the ETF user community including: 1) a heterogeneous group of systems delivering 1.67 teraflops on an ongoing basis with the capability to offer up to 6.26 teraflops for very demanding well-justified applications; 2) a baseline storage capacity offered as part of ETF would include 129 terabytes with peak demand contributions exceeding 400 terabytes; 3) access to a variety of visualization resources including a CAVE, an Immersadesk, Display Walls, etc. are also offered; 4) specialized instrumentation facilities including the Purdue Terrestrial Observatory, and the Service Crystallography at Advanced Photon Sources (SCrAPS); and 5) access to a number of large scientific data sets in the life sciences, earth system simulations, vegetation and soils research, multispectral remote sensing imaging, geological GIS data, economic and social scientific data, and anthropological data. Investigators at both Indiana University and Purdue University will also contribute significantly to the broader goals of the Extensible Terascale Facility. They have a significant concentration of expertise in areas of grid computing, middleware, and portal development. Both universities, through their IP-Grid participation, also have extensive outreach activities fostering the training and education of a diverse technological workforce extending from K-12 programs through undergraduate and graduate programs.
