Outline A Simple API for Grid Applications (SAGA):
The OGF (Open Grid Forum) Standard; JSAGA: a Java implementation of SAGA; A generic Grid Engine for Science Gateways based on SAGA; Grid Engine based on JSAGA; EGI Portal Policy & Grid Security Traceability; Grid Engine usage example.

A Simple API for Grid Applications (SAGA)
SAGA is an API that provides the basic functionality required to build distributed applications, tools and frameworks; It is independent of the details of the underlying infrastructure (e.g., the middleware); SAGA is an OGF specification: Several Implementations are available: A C++ and a Java implementation developed at the Louisiana State University / CCT and Vrije Universiteit Amsterdam ( A Java implementation developed at CCIN2P3 ( A Python implementation based on those above.

A Simple API for Grid Applications (SAGA)
SAGA is made of: SAGA Core Libraries: contain the SAGA base system, the runtime and the API packages (job management, data management, etc.); SAGA Adaptors: provide access to the underlying grid infrastructure (adaptors are available for gLite, ARC, Globus, UNICORE and other middleware); SAGA defines a standard We then need an implementation!

JSAGA JSAGA is a Java implementation of SAGA developed at CCIN2P3;
Enables uniform data and job management across different grid infrastructures/middleware; Makes extensions easily: adaptor interfaces are designed to minimize coding effort for integrating support of new technologies/middleware; Is OS independent: most of the provided adaptors are written in full Java and they are tested both on Windows and Linux.

JSAGA supports gLite, Globus,
JSAGA Adaptors JSAGA supports gLite, Globus, ARC, UNICORE, etc.

e-Token In order to strong reduce the risks to have the robot certificate compromised, the INFN CA decided to store this new certificate on board of the SafeNet eToken smart cards [6]; The AeToken smart card can support many certificates; A token PIN is prompted every time the user needs to interact with the smart card;

EGI Portal Policy & VO Portal Policy
The Portal, the associated Portal VO and the Portal manager are all individually and collectively responsible and accountable for all interactions with the Grid; The Portal must be capable of limiting the job submission rate; The Portal must keep audit logs for all interactions with the Grid as defined in the Traceability and Logging Policy (minimum 90 days); The Portal manager and operators must assist in security incident investigations; Where relevant, private keys associated with (proxy) certificates must not be transferred across a network, not even in encrypted form.

Users’ Traceability in Science Gateways
Two Tables: one for active Jobs and File Transfers and one for the finished ones. Example of entry in the Users Tracking DB GRID USAGE TRACEABILITY Common Name Portal User Name as stored in LDAP IP + Port IP address and TCP port used by the requester Timestamp Identify the grid operation date/time Grid Interaction Grid Interaction Identification (Job “X” submission, file upload/download). The portal MUST classify all the grid operations allowed. This value will allow to identify both applications used and operation performed. Grid ID Store the actual GRID Interaction ID (Job ID for job submission and some other relevant information for data transfer) Robot Certificate Identify the Robot Certificate used for the Grid Operation ID 70 Common Name fpistagna IP + TCP Port :8162 Timestamp :16:29 Grid Interaction 1 Grid ID [wms://infn-wms-01.ct.pi2s2.it:7443/glite_wms_wmproxy_server]-[ Robot Certificate /C=IT/O=INFN/OU=Robot/L=COMETA/CN=Robot: ViralGrid Science Gateway - Roberto Barbera Virtual Organisation cometa

JSAGA: Other SAGA Implementations: The C++ implementation developed at the Louisiana State University/CCT: The Java implementation developed at the Vrije Universiteit Amsterdam:

GridEngine Usage The GridEngine provides a set of java APIs to manage job execution into a distributed environment and a database to register any user Grid Interaction. While developing a Grid Application the user needs to identify: The Grid services to specify The input and ouput files The executable The three steps above can be easily identified, then written and tested with a small set of GridEngine API calls. This set of instructions can be used then inside the portlet concentrating the user to deal with the interface while developing the portlet

Let’s start - Checkout Hostname-standalone is here: Checkout:

Customize hostname.java: HOW TO?
In Order to customize hostname-standalone you have to: Add your input files into job directory; Modify the batch file /job/pilot_script.sh Use /job/standard_pilot_script.sh as a backup file batch; Modify hostname.java submitJob method; Compile hostname.java (slides page 24); Execute hostname.java (slides pages 25-26); Check Status and Output of the submitted job (slides pages 28-37); If everything is ok copy hostname.java submitJob method into java file of your portlet: /docroot/WEB-INF/src/it/infn/ct/hostname_portlet.java
