Missions

To build GRID infrastructures in Thailand

What is it? What is it for?

The Grid

CERN

The Large Hadron Collider (LHC) is the world's largest particle

accelerator.

LHC facts Circumference 26.7 km Luminosity Magnet 8.33 T current 11,700A superconducting cable 7600 km superconducting magnets

1,232 dipole magnets 392 quadrupole magnets

3410 -2 -1cm s

Temperature of 1.9 K 9.9999991% of the speed of light Period for a proton to travel once around

the main ring 90 microseconds Frequency 11,000 Hz Photon bunches 2,808 bunches The collision rate is one billion per second

Try to answer the BIG question• What actually happened at the big

bang?

and other questions

•How does gravity work?•How do particles have mass?•Where is the rest of the universe?

LHC Computing Grid The data stream from

the detectors provides approximately 300 GB/s

27 TB of raw data per day or 10–15 PB of data each year

These data is more than any single, current, system can handle

We need to find the system

that can handle massive amounts of data can process large computing jobs relatively inexpensive simple to use can access 24/7 easily upgraded

Why don’t we build a super Computers ?

very expensive very difficult to access obsolete quickly

Solution: using the Internet ? A Computing Grid

Grid Middleware

Using the Grid and middleware, all the user has to do is submit a job and pick up the results.

What is middleware?

Middleware is a computer software that

allows users to submit jobs to the Grid without knowing where the data is or where the jobs will run. The software can run the job where the data is, or move the data to where there is CPU power available.

•Tier 2 Center is a regional center.

•Tier 3 centers are at university or institute level.

To be a CERN site, the center have to contribute at least 200 CPUs and 200 TB for international users.

To be a tier 3 center, it requires to serve only local users in theiruniversities or institutes.

How to set up LHC GRID site?

The basic LCG site consists of UI User Interface CE Compute Element WN Worker Nodes SE Storage Element Site BDII Berkley Database Information Index MON Monitor Accounting service

Operating system SLC5

Middleware

The gLite middleware is produced by the EGEE project.

Details for each hosts

Host 1. Site BDII and CE  Host 2. SE Host 3. WN  Host 4. UI and MON

All hosts are needed to install both SLC5

and gLite.
