2 Introduction GENIUS/EnginFrame: new version 4.1 VOMS Proxy Init Service Robot Certificates Summary and Conclusions Outline

3 Grid technology allows users to share a wide pletora of distributed computational resources regardless of their geographical location. Virtual services are exposed to the users through rather complex Command Line Interfaces or API languages. Grid security is indeed based on the Public Key Infrastructure (PKI) of X.509 certificates and the procedure to get and manage those certificates is unfortunately not straightforward; Up to now, the high security policy requested to access distributed computing resources has been a rather big limiting factor when trying to broaden the usage of Grids into a wide community of users; + +

4 User has to adhere to a Virtual Organization (VO) User needs an account on one of the trusted User Interface (UI) + + = Grid portals provide an added value to make Grids more appealing for non-expert users.

5 5 A grid portal: why and how It can be accessed from everywhere and by everything (desktop, laptop, PDA, cell phone). It can keep the same user interface to several back-ends. It must be redundantly secure at all levels: –1) secure for web transactions, –2) secure for user credentials, –3) secure for user authentication, –4) secure at VO/VOMS level. All available grid services must be incorporated in a logic way, just one mouse click away. Its layout must be easily understandable and user friendly.

6 A Grid Portal improves usability of Grids –Lowering end-user requirements for accessing the Grid –Hiding the complexity of data and job services management in the Grid A Grid Portal improves utilization of Grids –Making the Grid (r)evolution transparent to the end-user –Providing an appealing user-friendly Web interface –Enforcing Grid utilization policies Grid Portal Benefits

9 What is EnginFrame ? It is a web-based technology able to expose Grid services running on Grid infrastructures It allows organizations to provide application- oriented computing and data services to both users (via Web browsers) and applications (via SOAP/WSDL and/or RSS) Its a Grid gateway It greatly simplifies the development of Web Portals exposing computing services that can run on a broad range of different computational Grid systems

30 Introduction GENIUS/EnginFrame: new version 4.1 VOMS Proxy Init Service Robot Certificates Summary and Conclusions

31 VOMS Proxy Init Service A CAPTCHA Code is required to start the VOMS Proxy Applet for the proxy initialization The Java plugin or higher is mandatory required.

37 Introduction GENIUS/EnginFrame: new version 4.1 VOMS Proxy Init Service Robot Certificates Summary and Conclusions

38 Robot certificates have been introduced to permit users, who are not familiar with deal personal certificates and dont belong to any VOs, to experience the Grid paradigm for research activity and reduce the initial barriers. –They are extremely useful for instance to automate grid service monitoring, data processing production, distributed data collection systems. –Basically these certificates can be used to identify a person responsible for an unattended service or process acting as client and/or server. Robot certificates in a nutshell

39 In order to strong reduce the risks to have the portal certificate compromised the INFN CA decided to issue this new certificate on board of the Aladdin eToken PRO 32K smart card. Each smart card can support several robot certificates: one for each application user wants to share with the other. –An users PIN is prompted every time user try to read the certificate stored on the smart card to generate a proxy. –A first prototype of Grid Portal using robot certificate to generate an users proxy has been successfully designed. Robot certificates in a nutshell

40 1. ask for a service 2. create a proxy with the robot certificate 5. get the results 3. execute action 4. get output 2,3. track user User Admin The GENIUS Portal & Robot Certificates

41 The Users Tracking System (UTS) ACL-based services that enable easier access control customization for users not belonging to any group!

42 Porting the MrBayes application to Grid Case study from CNR - ITB

43 General Introduction MrBayes is a program for the Bayesian estimation of phylogeny. Bayesian inference of phylogeny is based on the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. –To approximate the posterior probability distribution of trees MrBayes uses a simulation technique called Markov Chain Monte Carlo (or MCMC). The program takes as input a character matrix in a NEXUS file format. The output is several files with the parameters that were sampled by the MCMC algorithm. The application is CPU demanding, especially if the MPI version of the software is used.

45 Job Submission Tool: is driven by the concept of Task as the applications are – Each task could be independent or could be described as depended from another Task – Each task is described by a status – The task is executed by a wrapper that takes care of monitoring the task: If the task is correctly executed the wrapper can change the status of the task from Free to Done If a single step on the job execution fails, the whole task is considered failed and automatically rescheduled JST tool takes care of submitting jobs, retrieving the output and monitoring the status of each task It is able to deal with accidental failure of grid services It is possible to change at run time the priority of each task/application JST characteristics

47 Case study from Porting the ASTRA application to Grid

48 The ASTRA project in a nutshell The ASTRA (Ancient instrument Sound/Timbre Reconstruction Application) projects aims to reconstruct the sound or timbre of ancient instruments using archaeological data as fragments from excavations, written descriptions, pictures... The technique used is the physical modeling synthesis, a complex digital audio rendering technique which allows to recreate a model of the musical instrument and produce the sound by simulating its behavior as a mechanical system.

49 Modeling and computation on the Grid Computer model The Grid Network Reconstructed sounds Archaeological findings Load the sounds on a piano keyboard and play

50 How does ASTRA reconstruct the sound of the instruments ? The modeling process is known as Physical Modeling Synthesis Physical modeling creates a virtual model of the instrument and reproduces its sound by simulating its behaviour as a mechanical system. »This approach is also referred to as synthesis by rule. The higher is the quality of the audio files, the longer is the time required To have an idea of the needed time for simulation, on a Pentium IV 3.73 Ghz, 2GB RAM Personal Computer to correctly reproduce a sound lasting for 30 seconds it could be required more than 90 min.

53 Ancient Epigonion concert video now available In June 2009, the concert Fisica", was organized by the Catania Division of the Italian National Institute of Nuclear Physics. It was an important event which aimed at presenting the main achievements of the ASTRA (Ancient instrumentASTRA Sound/Timbre Reconstruction Application) project to the Cultural Heritage community and to the General Public. This world premiere showcased the sounds of an instrument of the past, reconstructed via computer-intensive modelling, being performed alongside real instruments such as violins and flutes as well as voices. The sounds of the Epigonion have been recreated by a team of researchers from the ASTRA project using the high-speed networks GEANT2 and EUMEDCONNECT

55 Introduction GENIUS/EnginFrame: new version 4.1 VOMS Proxy Init Service Robot Certificates Summary and Conclusions

56 GENIUS offers the following advantages: it is a complete production-ready environment which combines the concepts of user portal and science portal; absolutely no client software needs to be installed on the users workstation apart from the web browser with its usual plug-ins like Java (at least JRE or higher); it provides a new unique tool to authorize users, in a very strong secure way, into the grid environment with or without VOMS support as well, easy to use; it includes support for both single and composite jobs (including DAGs); interactive analysis and web access to personal spooling areas are possible; environment and settings customizable for the users; security for data management and sessions.
