Component Name
Description
Instrument Element (IE)
This is a unique concept to GRIDCC. It consists of a coherent collection of services which
provide all the functionalities to configure, partition and control the physical instruments
Information & Monitor Service (IMS)
It gathers from GRIDCC resources information and monitor data to be disseminated
through a publish / subscribe systems or to be stored in persistent repositories.
Problem Solver (PS)
It offers automated problem solving in a Grid environment at two levels. A local PS,
within a given Instrument Element, allows to solve local problems related to functionalities
of a given instrument. A global PS, allows to solve system-wide problems.
Virtual Control Room (VCR)
It provides a common set of collaboration tools and allows users to build complex
workflows, which are then submitted to the Execution Services, and to directly monitor
and control remote instruments in real-time.
Execution Services (ES)
They control the execution of the workflows defined by the user in the VCR, maintaining
the status of the tasks that make up the workflow.
They also support the advance reservation of resources.
Security Services (SS)
GRIDCC uses a split security system. When interacting with components of other Grids
the GSI security will be used and the users identified by their X.509 proxy certificate.
When interacting with the IE the user will be identified by a Kerberos ticket.

12. GRIDCC: other applications
Meteorology (Ensemble Limited Area Forecasting)
Weather forecasting system to detect hazardous weather
Device Farm for the Support of Cooperative Distributed Measurements in Telecommunications and Networking Laboratories
The Device Farm consists of a pool of Measurement Instruments for Telecommunication Experiments
Geo-hazards: Remote Operation of Geophysical Monitoring Network
The monitoring net will be characterized by different levels of activity: stand-by, pre-alert, alert, plus a control modality
An event worth to be monitored is for example the evolution of a “landslip”

13. Focus on new capabilities provided by GRIDCC
Instrument Element
Complete integration of Instruments into grid
High virtualization and abstraction of diverse physical devices
A very scalable and platform-independent component
A versatile multi-input / multi-output component
Fast Data Publishing System
High-performance reliable multicast via RMM-JMS
Virtual Control Room
Allows effective human interactions with the grid
Provides a homogeneous collaborative environment

14. Instrument Element: instruments into grid
The Instrument Element (IE) is one of the novel elements of the GRIDCC architecture.
It offers a standard web service interface to integrate scientific and general purpose instruments and sensors within the grid.
An IE can control a set of instruments with the possibility to decide on which sub-set to operate.
The IE is the key decoupling element between real instruments and the grid

15. Instrument Element: Instrument Virtualization
The IE grid instruments representation is basically based on:
Parameters: they hold configuration information
Attributes: they hold instrument variables

17. Instrument Element: Versatile I/O multichannel
The IE permits
grid accessible operations to control and monitor the instruments (via VIGS), such as:
execute a command
get / set parameters
different data outputs:
data mover to/from a grid Storage Element (via SRM)
high bandwidth channel for data publishing (via IMS).
low bandwidth channel for logs, states etc. (via IMS).

18. Fast Data Publishing: RMM-JMS
Same data are sent to several subscribers.
Multicast protocols can have a benefic impact on performances IE
IE Data Producer
Data Subscribers
JMS provides a standard set of
APIs for the communication
Many commercial and academic
JMS implementations
both in C/C++ and Java
(NaradaBrokering, Sun, IBM)
GRIDCC (IBM Haifa lab) has
implemented a Reliable Multicast
protocol (RMM) JMS compliant
RMM-JMS works within a LAN
but an efficient bridge technology
has been developed to allow
inter-LAN multicast communication

19. Fast Data Publishing: Some results
Message Rate: Case many-to-one
32 Dual Xeon 2.4GHz 1.5GB RAM machines, 1 GB Ethernet switch
At most 1 publisher, subscriber, or broker- (Sun MQ3.6) per machine
No message lost
RMM throughput: Mbytes/sec. (for 5 and more publishers)

20. Grid Virtual Control Room The VCR is a collaborative web portal
Enable the user to run, aggregate and display plug-ins that act as “mini applications”
Grid

21. Why could GRIDCC fit industry world? - I
High modular and flexible solution
The software installation is NOT monolithic, but organized in pluggable independent components
The IE architecture is not tied to specific technologies or third party software
Multiple and independent I/O interfaces: Commands and Controls directed to Instruments, IMS, Fast Data Publishing, Data Movement to/from the GRID
High scalability
GRIDCC is portable to different platforms
Target environment ranges from large farms to embedded devices
GRIDCC middleware is meant to be used in production environments
Mature middleware has been used, whenever possible, to assure robustness and stability

22. Why could GRIDCC fit industry world? - II
Fine customization of the Instrument Element
The IE is easily adaptable to diverse scenarios and needs
High level of abstraction in GRIDCC component interfaces
Service Oriented Architecture
Adherence to standards: WS-I compliant services
Standardized and uniform access to GRIDCC components
Services loosely coupled
Many different clients can interact with an IE, adopting WS-I compliant technologies (such as Java, LabView, Perl, C++, .NET etc.)
High interoperability
EGEE (gLite) compatibility
EGEE platform is one of the widely adopted solution for production grids
A frequent and diffused interaction of GRIDCC modules with production grids (WMS, CEs, SEs) is envisaged
Many grid facilities and tools can be reused (for instance GridFTP or SRM interface for data movement)

23. How to proceed and receive feedback ...
The dissemination activities MUST be continued and increased
New test-beds are to be set-up
Further training events and publications are envisaged
Large public companies and industrial stakeholders will be addressed more closely in the third year of the project life
