Virtual Laboratory: Exploring e-Science in CAS Kai Nan, Jianjun Yu, Xing Hang Computer Network Information Center (CNIC)Chinese Academy of Sciences (CAS) Xi’An, June 6, 2014
Outline • Motivation • e-Science and Virtual Laboratory • Current Work on VLAB • Planning in Future
The Definition of e-Science • Three kinds of e-Science: • Computationally intensive science in highly distributed network environments • Science that uses immense data sets that require grid computing • Distributed collaboration, such as the Access Grid • Examples: • social simulations, particle physics, earth sciences, bio-informatics, … • Cited from wikipedia
Why e-Science • Challenges in modern science research (from the view of scientific researchers ) • Science problems are more complex than ever • Science research object is not isolated, but cross discipline and large-scale • Science data processing, simulation and computing become indispensable methods • need more and more communication, collaboration, coordination among them closer than ever
Why e-Science • From the perspective of resources • Great total amount with limited utilization • Lack of effective usage of resources • Scientists need to collaborate sharing their resources and knowledge
Why e-Science • From the perspective of IT: • What researchers need • Huge demand for computing technologies • Huge demand for sharing the resource / collaboration • What provides • High speed network • HPC • Large scale of scientific data • How to provide • e-Science environment • Give scientists a more EASY-TO-USE interface to help them using the heterogeneous resources
What e-Science do • Provide a research collaborative environment • Combining all resources: including computing, network, data, human,….

Outline • Motivation • e-Science and Virtual Laboratory • Current Work on VLAB • Planning in Future
CAS 11th Five-year Informatization Program (2006- 2010) • Continue to develop the infrastructure and existing applications • e-Science Facility • Networks of field stations/instruments(60), Mobile equip., Digital library of natural resources • e-Science Applications • HEP, Astro, Bio, Geo, Chemistry, …(about 10 or 16) • Resource Integration Platform • Supporting Environment for Applications
Our vision of e-Science • Virtual Laboratory based e-Science • An integrated collaboration environment to supporte-Science • Composed of shared and collaborative hardware, software, data, information, human, …. • An EASY-TO-USE interface for scientific researchers • A basic form and tool for e-Science activities
e-Science VS. e-Science Virtual Labs • e-Science would be applications-driven • “Virtual Labs” , the key position in our e-Science framework ,the core component to make e-Science a reality • Should emphasize that Virtual Labs don’t mean make experiments online
Virtual Labs Solves • Virtual Lab is proposed to be • a basic unit of research activity in the e-Science environment • the right user interface between scientists and their e-Science environment
Virtual Labs Goals • With Virtual Labs, • all kinds of resources could be integrated into a single access point • customized and flexible services would be provided according to the specific requirements of different domains in an easier way than ever before • Multidisciplinary, multi-organization collaboration could be carried out online.
Features of Virtual Labs • Ease of use • much easier to use than current systems. • Resource integration • provide the user with a single operating environment under which many kinds of resources, such as supercomputers, mass storage facilities, scientific databases, digital libraries, high bandwidth link, scientific equipment, etc. could be accessed in a seamless way. • Customized service • provide a user with what he or she wants completely and exactly. Each user may have a specific workbench individually. • users may choose different services at different times or at different prices. • Ubiquitous research • benefit from state-of-the-art technologies on mobile computing and related so that user could use the Virtual Lab at any time and anywhere.
Features of Virtual Labs (cont’) • Collaborative work • enable a lot of scientists, who are from multiple independent institutions, from multiple sites across the world, and from different professional backgrounds, to work together on a collaborative project or a common problem. • Scalability • support hundreds of users from tens of institutions, but should work just as well for three or five users. • Management • interact with outer management systems, such as ARP in CAS, to help improve efficiency during the whole lifetime of a research project or other research activities.
Virtual Labs Goals in 2006- 2010 • Provide a virtual lab environment • Scientific Virtual Organization management • Scientists can access, organize and manage resource easily and transparently • Integrate resources from CAS, such as computing, storage, database, library • Document share and collaboration • Organize Internet-based activities, such as project review, conference • At least three e-Science applications on Virtual Labs • Biology • Astronomy • High Energy Physics • ...
VLAB Projects • Exploration of e-Science Virtual Lab with our vision • A product under Virtual Lab concept • We focus more on how to develop an e-Science environment for real scientific application
