1. Advanced User Support Amit Majumdar 8/12/10

2. Outline  Three categories of AUS  Operational Activities  AUS.ASTA  ASTA examples  AUS.ASP  AUS.ASEOT

3. Three Categories of AUS I.Advanced Support for TeraGrid Applications (AUS.ASTA) I.AUS staff work on a particular user’s code (some community codes) II.Guided/initiated by the allocations process II.Advanced Support for Projects (AUS.ASP) I.Project initiated by AUS staff (jointly with users) – impacts many users II.Optimally install software, maintain, train users III.Advanced Support for EOT (AUS.ASEOT) I.Advanced HPC/CI trainings II.Participate in workshops, tutorials (TG10, PetaScale workshops, SCXY) III.Interaction with other CI programs PlantCI, DataNet etc.

4. Update on Operational Activities  Bi-weekly telecon among AUS POCs from every RP site o Matching of AUS staff to ASTA projects, discussion about ASP, EOT activities o Program plans, annual reports etc.  Web/Tele-con among AUS technical staff o Biweekly technical tele/web-conference on ASTA and other projects - using readytalk o Since we started (early October, 2008) 43 tele/web-con sessions o Slides and recorded audio archived at: http://teragridforum.org/mediawiki/index.php?title=Technical_presentations

5. ASTAs Total ASTAs: 47 ASTAs current including startup and supplemental ASTAs ASTA reminder news posted before TRAC deadlines Around 15 ASTA requests/TRAC coming in Now there is mechanism in POPS to record ASTA “allocation”… (little complicated)

6. Some Successful ASTA Examples (there are many more) SCEC SC10 paper Gordon Bell finalists ( ~220 TF/Jaguar) – possible due to significant ASTA effort over years from many ASTA staff from multiple RP sites Yifeng Cui, Amit Chourasia (SDSC) co-authors in SC10 paper User Kolmakov’s (U. Pitt) serial code’s kernel implemented in CUDA – initial effort ~16X improvement (205ms/iter to 13ms/iter) – AUS staff Carlos Rosales-Fernandez (TACC) Complex Fluent simulation of nuclear reactor thermal properties – Completed rigorous mesh independence and domain independence tests and validation with known (analytical) results for Single laminar isothermal round jet, 2d axisymmetric Continuing for other complex cases – moving to TG machines AUS staff Anirban Jana (PSC)

7. Advanced Support Projects Six projects – Benchmarking Molecular Dynamics codes (SDSC, PSC) Completed first phase Continual process as new machines are added – Benchmarking Materials Science codes (PSC, TACC, LONI) Completed first phase Continual process as new machines are added – Hybrid Programming model for multi-core (TACC, SDSC, PSC, NICS) jointly with XS-WG – continuing About to write report and publish from AUS projects page

8. Advanced Support Projects…cont.. – Investigation/benchmarking of PGAS languages (TACC initially; others will join later) – MPI, UPC comparison ongoing – Performance, profiling tools (PSC) TAU tutorial and documentation posted on AUS projects page – Software/database to monitor apps usage on resources (NICS) Helps US staff in software management

9. ASP Webpage Doc group has helped in setting up the AUS projects webpage After Liferay migration it is at : https://www.teragrid.org/web/user-support/aus_projects

10. Advanced Support EOT….some examples – AUS staff continue to teach HPC/CI tutorials at RP sites, TG10, SCXY etc. – AUS staff involved in organizing/participating in PetaScale Workshop series (last one at Austin in March 2010 – Petascale I/O) – Strong participation in TG10 – organizing, teaching, presenting – AUS staff reviews TRAC proposals – both as regular reviewers and as reviewers of smaller proposals (great help according to Kent Milfeld)

11. Without US there is no AUS
