Achievements after M24 |
| WP1
CrossGrid Application
Development |
Task1.1: Integration and
deployment. CYFRONET takes part in the Subtask 1.1.4:(together with UvA, Univ. Linz)
- a testbed will be realised and the
various components of the system will be integrated and deployed on it. |
See Task 5.2

Grid
Application Programming Environment |
Task
2.4: Interactive and semiautomatic performance evaluation tools
- will develop on-line tools that allow
application developers to measure, evaluate, and visualise the
performance of Grid applications with respect to data transfer,
synchronisation and I/O delay as well as CPU, network and storage
utilisation. CYFRONET will define performance measurements as well as
develop a tool/monitor interface and GUI. |
G-PM Tool for
Application Performance Evaluation: the range of available measurements
has been extended with metrics related to collective communication and
synchronization operations; support has been added for user-defined
measurements, e.g. operation counts. Communication with the OCM-G
monitoring system is now built on Grid-based mechanisms.
Visualization functionality was extended by Histogram, Piechart, and
Communication Matrix display windows, adjustable to the specifics of
performance measurements |

New Grid Services and
Tools |
Task 3.3: Grid monitoring
- all partners of this task will work out
the design specification of the monitoring tools. CYFRONET will define
the functionality of the monitoring environment to support tools’
needs in compliance with a standardised interface as well as develop the
corresponding modules of the infrastructure. |
OCM-G application monitoring system:
the system has been successfully implemented and deployed on all project
sites. OCM-G has been successfully used to monitor parts of the CrossGrid
flood application, submitted via Globus and running on multiple nodes, at
the same time cooperating with the CrossGrid G-PM tool, used to visualize
the application's execution based on data from OCM-G.
JIMS – JMX-based grid Infrastructure Monitoring System:
new functionality has been implemented, including monitoring agents for
Linux/Solaris and SNMP, active discovery of entities and a SOAP Gateway. |
| Task 3.4: Optimisation
of data access - will design and implement a system for data
access time estimation. The development of the service tool is mainly
devolved to CYFRONET, an institution having a wide experience in the
field of data management and archiver systems. |
The second
prototype has been released. The main characteristic of the second release
include full integration of data access cost estimation with EDG Optor/Reptor,
being the result of very good cooperation between task 3.4 and EDG WP2.
The provided solution estimates data access cost inside storage nodes for
different kinds of storage devices, including hard drives, DiskXtender HSM
working with automatic tape libraries and magneto-optical jukebox, as well
as the first prototype of data access cost estimation for Castor HSM. The
software is based on modern a Component-Expert architecture, which makes
the solution flexible and open for future problems. |
| Task 3.5: Tests
and integration - CYFRONET together with other partners in this
task, will test all tools and services of WP3 to be able to deliver a
middleware layer in the CrossGrid testbed, which will be used by the
Applications (WP1) and the Grid Application Programming Environment
(WP2). |

| WP4
International Testbed
Organisation |
Task 4.1:
Testbed
set-up and incremental evolution - the aim in this task is to
obtain an infrastructure as flexible as possible that will provide
testbeds for other WPs to develop and test their work. Several testbeds
will have to coexist offering different services and levels of stability
- one of the testbed sites is CYFRONET. |
The Cyfronet cluster has been recently upgraded to 80 Intel processors
(2.4 - 2.6 GHz) and 4 TB disk storage; interfacing to UniTree tape storage
(10 TB) has been tested; the HP ProCurve Switch has 40 ports 100Mb/s and 1
port 1Gb/s (uplink). Part of the cluster is identified as CrossGrid
testbeds, part will be reserved for EGEE, and the remaining processors
will be used as an LHC Computing Grid production cluster - the Cyfronet
site was one of the first to be included in the world-wide computing Grid
for particle physics (http://mapcentre.rl.ac.uk/graph_World.html).
An upgrade to LCG2 software is now being planned. |
| Task
4.4: Verification and quality control - verification and
evaluation of results, e.g. verification of middleware and applications
conformance will include verification of: testbed components before
production release, middleware and application interoperability,
policies and practices, independent review of applications, architecture
review of major testbed releases. CYFRONET will contribute taking care
of issues related to WP2 and WP3. |

Project Management |
5.2
Architecture Team |
- Definition of the
software architecture of the Project, identifying dependencies between
subsystems and developing a layered model of Grid architecture to make
CrossGrid an integrated software environment for Grid application
developers as well as users. An important part of this work is to follow
recent advances in the area of Grid technologies (with particular focus on
the emerging OGSA standard), and to conduct analyses and draw up plans on
how to prepare CrossGrid software for future compatibility with new
service-oriented standards in Grid computing.
- Identification of distinct types of human
users and proposing novel support for interactivity in the Grid
environment. As an example, one can mention the medical application
(WP1.1), where interaction with of a human with a running simulation and
runtime steering of that simulation is required. This goal is achieved by
the High Level Architecture (HLA) standard. CrossGrid work has resulted in
designing a system that will provide fault tolerance for such applications
running in the Grid environment. |
| 5.3 Central
dissemination |
- Organization of various
Grid events, including major conferences (the first and second AcrossGrids
conferences); workshops (Krakow Grid Workshop - three editions in 2001,
2002 and 2003), Project exhibitions - IST2002, IST2003, Open Grid Day,
Barcelona 2003, German Grid Day, Heildelberg 2003; Grid tutorials - Globus,
EDG, Unicore, GridLab/Cactus tutorial (2002), EuroGrid, Globus Toolkit 3.0
(2003).
- Cyfronet, in cooperation with other CrossGrid Partners, has prepared a
prototype CrossGrid tutorial. In the future, this tutorial will be
finalized and used to support various groups of Grid technology users in
Europe. The tutorial was presented for the first time during the ANWIRE
Winter School on Middleware (Jan 2004). |
