Vacation Camp 2005 & 2006

– About 70 students & teachers per year

Jointly organized by

• Infrastructure

– A PC grid linking Hwa Chong Institution and Raffles Institution with 200 United Devices clients

• Participating Schools in vacation camp

– Hwa Chong Institution – National Junior College – Raffles Institution/Junior College – Temasek Junior College – Victoria Junior College – Dunman High School – Anglo-Chinese School (Independent) – Nanyang Girls High School – Raffles Girls School – Maris Stella High School – River Valley High School – CHIJ St Nicholas

• Beyond vacation camp …

– Raffles Institution

• Mentors: Zhang Xinhuai

(NUS) & Dr. Bryan Lee (BII)

• Project: Auto-docking

– Hwa Chong Institution

• Mentor: Dr. Li Haizhou (I 2R)
• Project: Speech modelling

Enabling Autodock for a Grid Enabling Autodock for a Grid Environment Environment

• Computational prediction of ligands binding to

protein target

• Well-established docking tools/algorithms for

protein-ligands docking from The Scripps Research Institute

• A computational technique used for

– Drugs/Potential-Drugs discovery & development – Protein-Drugs interaction studies

• Source code available for academic

development

Why Grid Why Grid-

• enable Autodock?

enable Autodock?

• Issue:

– Docking of chemical library against a protein target – Chemical library consists of thousands to millions of ligands – Docking of 1 ligand will take approx 6 to 12 hours – A screening job of 1000 ligands may take 6000 – 12000 hours on single computer

• Objective:

– Shorten the time to obtain docking results

[Courtesy of Raffles Institution team]

What Was Done What Was Done

• Approach

– Break down each job into smaller execution units.

• Identify which parameters have to be changed

– Each execution unit is distributed to different machines on the Grid which process them separately. – Retrieve the results from each computer and compile them to get the final result.

• Each result is concatenated to form the final result.

[Courtesy of Raffles Institution team]

Benefits Benefits

• Speed increase of over 50%

– Test job (5 workunits of 50 results) took approximately 23 hours – Computational time on a single dedicated machine would have taken more than 50 hours – Limited increase due to lack of computers. There will be a larger speed increase on a bigger grid. Grid computers may not be dedicated, restricting the speed increase

• Running job on multiple computers

– In case of failure on one computer, the server can re-submit to another computer

RI RI -

• Conclusion

Conclusion

• Good experience
• Exposure to grid environment coding
• Learn to work together better
• Successful completion of 1st grid enabling

attempt

• Reflections

– Grid-enabling an application is challenging (for 1st- timers) – Grid computing has great potential in computationally intensive tasks

Grid Grid-

• Enabling Speech Processing

Enabling Speech Processing

Speech Recordings Separate the pitch tracks (fundamental frequency) Determine if there are 0, 1 or 2 people speaking Detect single speaker segments

[Courtesy of Hwa Chong Institution team]

What I t I s For What I t I s For

• When input voice consists of more than 1 speaker, it is

hard to transcribe the extra one voice

• Identify & differentiate the voices
• Multipitch - part of speech recognition system used for

e.g. meeting transcription

• Why grid-enable the application?

– 36GB data to be processed! – On a single PC, estimated time required to process all data is

285 days!

– Impractical to run on single PC for 285 days – No dedicated PC to process the data – Grid-enabling can speed up processing

• HCI will start on their project in April.

• Infocomm Clubs

– Aim: Promote interests in ICT among school students – Provide subsidies for hardware/software & services – Students earn Co-Curricular Activities points for participation for 60 hours involvement each school year – For each technology area, an appointed technology partner & service providers conduct courses, competitions, seminars, etc.

• NGO is appointed IDA’s technology partner in Grid

Computing

• 2 tracks: Build & Use
• Build Track

– For the more IT savvy & technically inclined students – Undertake grid-enabling efforts of an application of choice

• Use Track

– Digital media animation rendering applications – Life Science applications
