Why Engin. Frame? n Common problems: – Distributed Resource Managing solutions acceptance and usability – Client access: Windows-Unix integration – Policy enforcement – Collaboration with customers or partners – Data management on WAN – Pressure from Enterprise-wide projects n No expertise for Technical Computing problems among “traditional” web players
What is Engin. Frame? n Inter/Intranet access to computing resources n Any-client can connect through any browser n High scalability & flexibility for any resource n n n Based on the existing command-line Flexible in content presentation Easy to use, setup and manage – Thin/Fat clients, appliances, PDA, Wireless, . . . – Access an arbitrary number of HW & SW resources (clusters, stand-alone hosts, …)
Engin. Frame (R)evolution 1. x - LAN Integration (1998) » Unix-Windows NT Integration » Simplified parallel and distributed computing, … – Developed in collaboration with Compaq 2. x - WAN Meta. Computing (1999) » Standards convergence » Dynamic contents management 3. 0 - Computing Portal Infrastructure
CLIENT WEB SERVER RESOURCES HO W? Users “browse” the Computing resources as easily as a Web site. Collects Resource offers and creates HTML pages and forms to interact with. Agents “publish” service offerings as XML and act on servers’ request WHY? Engin. Frame three tier model Standard Web browsers allow broad accessibility and very positive user experience Web servers with servlet engine are becoming a standard XML can describe many different kinds of services (LSF clusters, standalone, …)

Engin. Frame features n Built on standard technologies – Open to Grid standards (Globus, Grid. ML) – Easily extensible to Open Grid Service Architecture (OGSA) specs n n Interfaced with leading 3 rd party tools Flexible data management – – – n Support for input/output data transfer Support for remote access to centralized data Native XML representation of data Flexible security management – Support data encryption (via SSL server) – Authentication: NIS, Domain, AFS, Grid/Globus, etc.
Engin. Frame service description n n Describe service options, actions and information Intuitive design Fast and easy prototyping Use your preferred XML editor SCREEN CAPTURE OR OTHER IMAGE
Engin. Frame user experience n n User logs in and provides his/her credentials Browse through service offerings Fills the required data form and (if needed) specify his/her input files Submits his/her request for the job
Security Open architecture to support different security policies n Directly supports HTTP authentication and plain-text authentication n Connection can be secured with SSL or VPN n Security plug-ins available for most common protocols (AFS, Globus GSI, Nfuse, …) n
Engin. Frame Benefits n n n n n Hide the complexity of Technical Computing environments Instant migration to the Computing Portal paradigm from a command based world Enhance resource Manageability for System and Application managers Enable smooth NT-UNIX-appliance integration Ease deployment of new software and methodologies Automatic and transparent enforcement of company policies Simplify resource Accessibility in the Virtual Workplace Enhance collaboration with remote sites and partners Protect your Intellectual Property Shorten Time-To-Market/Time-To-User
OUTLINE NICE Company Profile n IT Evolution and visions n Enginframe Architecture & Features n Service overview n Case Studies n Future Perspectives and Outlook n Summary and Conclusions n
Service overview n The basic building block of the portal is the Service n A Service is an XML representation of any Computing related action – a Service might be a FEM solver execution, a parallel Job based on MPI, a query to the LSF master to find my pending jobs, etc. n Services are designed focused on their users – A Service should be self-explaining – It should make life easier for the user
Service structure n n n The Service is basically described by – a service name – a service description or help (info) – the options requested to the user – the command (action) to be executed when the service is requested None of these items is required Service behavior highly depends on the presence of such items
XML terminology n Tag or Element - an item enclosed in <>, which is part of an XML document – e. g. n Attribute - an option of a tag, which has a name and a value enclosed by single or double quotes – e. g.
EF Rendering pipeline Engin. Frame Agent EF XML file Service results are added Engin. Frame Server Special tags are expanded XSLT Processor Templates are applied To browser The rendering pipeline enriches and then transforms the EF XML files n Customization can be at Agent-level and/or through an XSLT style-sheet n 
Choosing the right layout n n One very effective method is to select one existing page from your Intranet/Internet site You need to identify a page where you can figure out the space for the service navigation bar and the service content area

Benefits n n n Great savings in time, travel and logistic costs Simulation from anywhere, in any moment All existing infrastructure is left intact – no additional/dedicated HW and software – no administrative efforts to set-up a new farm n Intellectual property is fully protected – only specific files can be returned to the user – pre-coded simulation scripts n No training needed 
Case Study: Time to User Full ASP set-up in 1 day! 
Case Study: Data Exchange Collaboration problem in the supply chain n Many suppliers with different supported 3 D models n Complex operations to convert files n Management not comfortable with uncontrolled data exchange n User friendliness 
Solution: Engin. Frame Data. Gate 
Case study: a portal for Data. Grid Problems: n Scientists only care about their applications and not about the technicalities to run them n They are too lazy to learn new command line interfaces n The middleware services and the ways to access them change very rapidly 
The solution: Engin. Frame GENIUS: The Grid Portal for Data. Grid 
Benefits n Independence from Middle. Ware changes: – Transparent to the users – The user is guided in his/her choices n Independence from Layout changes: – The services mantain the same structure – New graphic look & feel can be easily implemented n Intuitive use

What does XML mean? n n XML files must be well-formed An XML is well formed when: – There is exactly one element, called the root – the elements, delimited by start- and end-tags, nest properly within each other – each element attribute is delimited by single or double quotes n XML files are case sensitive n All XML files in EF must be well formed
