Applications on BalticGrid

Application Identification and Support

This BalticGrid activity is carried out in three tasks:

• Pilot applications – applications from High Energy Physics, Material Science, Bioinformatics
• Special Interest Groups – implement and improve communication among many separate research groups, by using grid technology
• Application Support – organize and initiate communication between application experts and grid experts, employ suitable software tools

High Energy Physics Applications - HEP

This group of applications include:

• CMS (Compact Muon Solenoid) application

The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors being built on the proton-proton Large Hadron Collider (LHC) at CERN and approximately 2300 people from 159 scientific institutes form the collaboration building it. CMS is designed as a general-purpose detector, capable of studying many aspects of proton collisions at 14 TeV, it contains subsystems which are designed to measure the energy and momentum of photons, electrons, muons, and other products of the collisions. CMS is quite well suited to the grid as the grid has been originally designed and deployed for exactly such applications

• LHCb (Large Hedron Collider beauty) application.

The LHCb experiment, beside fundamental research, is at the moment used for the purposes of testing BalticGrid infrastructure, – it is well suited for it. Technically full simulation software for LHCb experiment is producing Monte Carlo data in the same form as a real detector and processing them by a reconstruction program. The output data is a collection of events written in the format as expected from detector electronics (Raw Data) or in the processed form of Event Summary Data. Statistical data analysis is following both experiments and is based mainly on the Monte Carlo technique, of different kind for each experiment. The procedure requires submitting a large number of CPU intensive jobs, each consuming a few hours on an average CPU unit. The testing procedure helped very much to make the BG operational infrastructure more reliable and stable, also some statistical methods were used by some other applications.

Material Science applications

• Material Science computing is based on GAMESS, GAUSSIAN and DALTON (+MolPro and others, in addition) and has well established tasks:
• large scale modeling:
• of the kinetics of meta-stable systems with application to advanced electronic materials modelling
• of nano-particles condensed matter physics, computes the energy of an assembly of nuclei and electrons placed in a repeated cell.
• Applications of Material Science are now moved to VO GAMESS, under separate SIG, covering software mentioned and attracting numerous users from Lithuania and Latvia.
• GAMESS

• DALTON application on BalticGrid

DALTON is a program for quantum chemistry tasks too and is complementary to GAMESS. It is installed and ready to use.

Bioinformatics Applications

Codes for the following functions are implemented (and continued to adapt):

• sequence pattern discovery and the gene regulatory network reconstruction,

Pattern-matcher: there is gridified application called triesearch, which is used for searching of patterns from Ensemble gene database. User can set search parameters for triesearch and then use daemon for submitting jobs.

• modeling of biosensors and other reaction-diffusion processes, now it is moved to separate SIG - see next link

Special Interest Groups - SIG

The BalticGrid SIGs bring together people working on the analysis, design, implementation and evaluation of research tasks, where group-to-group cooperation of scientists is needed. BG SIGs provide an international, interdisciplinary forum for the exchange of ideas and research results. For this moment there are 11 SIGs (some others are coming soon), presenting separate research areas:

Application Support Procedure

The main objective of the "Application Support" in the Baltic Grid project is to help application developers in adapting their applications to work in a grid environment. In order to achieve this goal the application support team has defined the process by which application developers can apply for help and assistance in porting their applications on a distributed computing environment like the Baltic Grid infrastructure.

On-line Monitoring of Grid Applications using OCM-G

In the process of development of Grid applications, various tools are helpful in order to find bugs in the application (debuggers) or to examine if the application is performing well (performance analyzers). Such tools require a facility that allows to obtain the information about the running application or even to manipulate its behavior. This functionality is provided by the OCM-G Monitoring System.

Parallel Pipe

Parallel pipe is a program designed to allow commands to be run in a grid/cluster environment. Such environments provide parallel execution of many tasks, so we can distribute our work across many nodes. Therefore our command has a chance to be run much faster than in a normal way. Not to mention that usage of this tool is very simple and intuitive.

Migrating Desktop Platform - graphical front-end to the grid

The aim of the Migrating Desktop is to provide scientists with a framework which hides the details of most Grid services and allows working with grid application in an easy and transparent way. The graphical user interface integrates and makes use of number of middleware and integrates the individual tools into a single product providing a complete grid front-end.
