Sub Theme 5

RENKEI Project Sub Theme 5 - Evaluation and Collaboration with Users -

Goal †

To enable e-Science communities, we make bridges between scientists who research on e-Science infrastructure systems/services and who research on application areas, including HEP and bio, that potentially require cyber-collaboration.

To achieve this goal, we will build a distributed computing environment that includes supercomputers from computer centers and shared data storages which are accessible from these supercomputers. e-Science system researchers develop/test/deploy their systems/services on the environment and application area researchers use them to proceed their research. We also provide a communication space between these two type researchers to apply feedbacks from researchers who use systems/services to the e-Science systems/services.

Proposal - RENKEI-PoP †

We propose an appliance for e-Science environment and named it RENKEI-PoP (Point of Presence). RENKEI is an abbreviation of "REsources liNKage for E-scIence" and means "federation" in Japanese. A RENKEI-PoP is just a storage server which has a large amount of data storage, high speed network interfaces, and a support for running VMs on it. Its software is open source softwares, including linux kernel, kvm, libvirt, gfarm, globus, etc.

RENKEI-PoPs are installed in computer centers in universities and research institutes (NIS, national infrastructure system, resources) as a gateway server, and tightly connected with local resources and loosely connected with each other over the Internet or VPN for specific research projects to form a distributed computing environment. Here 'tightly' means that RENKEI-PoPs use the same network or authentication system with local resources, such as supercomputers and data storages, and 'loosely' means that they are on the same grid infrastructure.

A RENKEI-PoP distributed computing environment provides the following services.

Distributed filesystem
It gives a transparent data access between supercomputers and data sources, such as archives, generators. To enable a distribute filesystem, we use Gfarm that is developed by RENKEI Project subtheme 2.

Virtual machine hosting
To federate supercomputers and data sources which are geographically distributed and operated by different policies, we need to have services for this purpose and actually other subthemes in RENKEI project are developing them. We, sub theme 5, developed and deployed a distributed virtual machine management system, named RENKEI-VPE (virtual private environment), on RENKEI-PoPs to host such services. RENKEi-VPE is built on other existing open source softwares, such as libvirt, kvm, OpenNebula, and Gfarm.

Access services
We also provide several methods to access and upload/download data from the environment. Currently, OpenSSH, GSI-SSH, gridftp and gfarm-client are available.
