Cyberinfrastructure is the connective tissue for computational science, tying together the research projects, resources, software, data, networks, and people needed to make important discoveries. In an era where soon all research will be computational science, to varying degrees, the importance of building strong cyberinfrastructures to support that research grows -- as do the challenges. But what will the cyberinfrastructures of the future look like?


Chameleon: Why Computer Scientists Need a Cloud of Their Own


It's been almost a year since Chameleon, the experimental cloud computing testbed co-run by the Computation Institute and Texas Advanced Computing Center, went into full production for research use. Already, 600 users and 150 projects have used the system to test new uses and technologies for cloud computing, from finding unknown exoplanets to preventing cyberattacks. Last week, HPCwire spoke to CI Senior Fellow Kate Keahey and other members of the Chameleon team, surveying its early successes and previewing the innovations still to come.


Software helps people harness the power of computing for the task of their choice, be it analyzing a genome or streaming a movie. But platforms provide the next level of computational potential, enabling easy access to software for users and a strong foundation for developers to build upon and distribute their work. A good platform example is iOS, the operating system for mobile Apple devices, which through its app store and programming language allows worldwide distribution of software, near instantly, at low cost.

The Discovery Cloud is CI Director Ian Foster's vision to deliver powerful computational tools and methods to every professional and amateur scientist around the world, fundamentally transforming the ecosystem of science. Globus is the first step towards realizing this vision.

Nimbus logo

Nimbus is an open-source toolkit focused on providing Infrastructure-as-a-Service (IaaS) capabilities to the scientific community. Nimbus enables providers of resources to build private or community IaaS clouds, users to use IaaS clouds and developers to extend, experiment and customize IaaS. Combining those tools and capabilities in different ways allows users to rapidly develop custom community-specific solutions.

Globus Online Logo

Globus Online is software-as-a-service for research data management. It enables researchers to easily and securely move big data and share it with collaborators around the world. As a cloud-hosted service, Globus Online makes it easy for resource owners and system administrators to deliver advanced data management services to their users.
