Workshop Stat.• Total of 38 registered participants

– In person: 30– Remote: 8– HEP:26– CSE+HPC:12

• Four different remote conferencing technologies– 2 video conferencing– 2 teleconferencing


4

Why are we here?

• To mark the new beginning of a Texas alliance • High Performance Computing Across Texas

(HiPCAT, http://www.hipcat.net/) organization is a consortium of many universities in Texas to collaborate in bringing high level computing to the community spanning wide ranges– Education– Research– Industry

http://www.hipcat.net/


5

Why are we here, cont’d• High Energy Physics anticipates large amount of

data (over several Peta Bytes – million GB, 10000, 100GB drives) to be shared throughout the world– Provide excellent problems to solve through cutting

edge technology• Construct a nucleus grid that must solve

immediate problems • Bring computing grid technology one step closer

to every day lives to improve quality of life• Need to promote grass root effort in Texas


6

High Energy Physics in Texas• Several Universities

– UTA, TTU, SMU, UTD, TAM, UH, UT, Rice, UTB, UTEP, etc• UTA and TTU play leading role in their Tevatron experiments

• Many different research facilities used– Fermi National Accelerator Laboratory– Jefferson Lab– Brookhaven National Lab– CERN, Switzerland, DESY, Germany, and KEK, Japan– SLAC, CA and Cornell– Natural sources and underground labs

• Sizable community, variety of experiments and needs• Large data (~1PB/experiment) now!!

650 Collaborators78 Institutions18 Countries

DØ Collaboration

A Solution Computing Grid• Grid: Geographically distributed computing resources

configured for coordinated use• Physical resources & networks provide raw capability• “Middleware” software ties it together

Many small grids could form a larger grid.

DØ Southern Analysis Region (DØSAR)

• One of the regional grids within the DØGrid• Consortium coordinating activities to maximize computing

and analysis resources in addition to the whole European efforts

• UTA, LU, OU, LTU, SPRACE, Tata, KSU, KU, Rice, UMiss, CSF, UAZ

• MC farm clusters – mixture of dedicated and multi-purpose, rack mounted and desktopdesktop, 10’s-100’s of CPU’s

12

Where are we and where do we want to go?• Grid solutions are being implemented and used• Discover additional computing resources• Accumulate local expertise to help each other• Data analysis at remote universities being done• Operational grid producing MC samples• Time to work with each other within Texas to

maximally utilize the ample resources• Help expediting realization of computing grid


13

Workshop Goals• Primary goals:

– Kick-start Texas High Energy Grid, THEGrid – Prepare THEGrid sites for the "grid" environment (Globus,

Condor, etc.) via hands-on sessions– Understand the software & hardware requirements – Set clear goals and their corresponding time scales for

eventual integration of THEGrid into the global grid activities, such as Grid3 and Open Science Grid

– Decide on work assignments for participating institutions – Identify available resources within the field in the state of Texas– Set common goals, task lists and schedules

• Distribute tasks• Establish clear road map and milestones for the future


14

Workshop Program


15

Demo Plan This Afternoon• HyunWoo Kim: UT Arlington

– Demonstrate the operation of the DØ Southern Analysis Regional Grid (DØSARGrid) using McFarm Software

– Submit an official DØ MC (Simulated) events– Display the submitted request status on JIM– Display the status of the job at the destination cluster– Display the status of resource consumption

• Joel Snow, Langston University, Oklahoma– Demonstrate the operation of more generic DØGrid which

involves primarily European clusters– Display the submitted request status on JIM

• Alan Sill, Texas Tech University– Demonstrate the operation of CAF, CDFGrid


16

Hand-on session

• Globus or VTD installation• Condor desktop farm installation• Certificate application and (perhaps) installation• Demo for how to add approved users' certificate

for them to submit jobs• ganglia installation• MonaLISA installation• SAM/Grid installation


17

Some Workshop Arrangements• Your package includes your name tag, program,

a pen, and a pad• Coffee and other refreshment are in next door.

Help yourself at any time.• The banquet is at 7:00pm tonight• Tomorrow morning’s session begins at 9am here

in room 200.
