The Advanced User Support (AUS) Area encompasses the following activities:

  • AUS.ASTA
    • Under this subarea AUS staff work on Advanced Support for TeraGrid Applications (ASTA) projects where users have requested advanced support for their applications. These user requests are reviewed by the TRAC and the reviewers' recommendation is taken into account to decide which user will receive ASTA support from AUS staff.
  • AUS.ASP
    • Under this subarea AUS staff work on some projects which benefit many users. Example of such project is benchmarking, optimizing, and profiling Molecular Dynamics (MD) codes on all the TeraGrid machines and providing a detail technical documentation for users with all these information. This can help users decide which machine to use for most effective MD simulations. This also helps users write their allocations proposal and helps TRAC reveiwers to check the performance results that users present in their allocation proposals.
    • Under AUS.ASP AUS staff also collect and provide to the general user community exemplary usage of TeraGrid resources.
  • AUS.EOT
    • Under this subarea AUS staff provide technical content for advanced CI/HPC topics that are used in TeraGrdi trainings and workshops. Various other outreach and hosting of workshops also fall under this AUS subarea. For this AUS staff work closely with the EOT area, the XS-WG etc.
  • AUS Higher Level Goals and Tasks
    • This doc contains description of higher level goals and tasks for the AUS area.

Meetings (minutes archive and technical presentation archive) and Mailing List

  • AUS POCs' telecons : alternate Thursdays 11am - noon PST
    • Attendees are the AUS POCs from each of the RP sites (in these telecons management and coordination issues are addressed e.g. matching of appropriate AUS staff to AUS.ASTA, AUS.ASP, AUS.EOT projects etc.)
    • AUS POCs' Telecon minutes 2008 2009
    • AUS POCS' Telecon minutes 2010 2011
  • AUS technical staff webconference : alternate Thursdays 11m - noon PST
    • Attendees are all the AUS technical staff from all the RP sites (in these tele/web conference, using readytalk, AUS staff present and discuss technical issues of various projects e.g code scaling, performance results, performance tools usage, single processor performance, programming models etc.)
    • Technical presentations
  • AUS technical staff teleconference : these are held as needed mainly to initiate or discuss technical issues related to AUS.ASP
  • AUS TeraGrid email list is : aus at teragrid dot org
    • Subscribe by sending email to majordomo at teragrid dot org with "subscribe aus" in the body of the message or email Amit Majumdar (majumdar at sdsc dot edu) for subscribing to this email list

AUS Molecular Dynamics Advanced Support Project(MD ASP)

  • As a part of this ASP we plan to port, benchmark, profile various Molecular Dynamics (MD) codes on various TG machines. We will provide all the detail technical information, via web (and possibly via training and workshops) to the MD user community. In addition to always having the optimally installed MD codes on various TG machines, this project is expected to benefit MD user community in multiple ways such as (1)gain knowledge about performance (and scaling limitations) of MD codes on various machines, (2) know about the optimal compiler and libraries to use on TG machines, (3) help with justifying resource requests in allocation proposals, (2) efficiently install own version of codes on TG machines etc. This may also help TRAC reviewers cross check users' resource request justification in their allocation proposals.
  • Currently involved in the project: Ross Walker (SDSC), Phil Blood (PSC), Wayne Pfeiffer (SDSC), Marcela Madrid (PSC)
  • Following MD researchers were contacted to get their input about this project:

Klaus Schulten (UIUC); Adrian Roitberg (U. Florida); Greg Voth (U. Utah); Tom Cheatham U. Utah); Andy McCammon (UCSD); Carlos Simmerling ( Stony Brook U.); Michael Klein (U. Penn); Benoit Roux (U. Chicago); Aleksei Aksimentiev (UIUC); Charlie Brooks (U. Michigan); David Case (Rutgers); Michael Crowley (NREL); Michael Feig (Michigan State U.)

AUS Materials Science Advanced Support Project(MS ASP)

  • In this project we plan to port, benchmark, profile various codes that are primarily used for Materials Science (MS) simulations. We will provide detail technical information, via web (and possibly via training workshops) to the MS user community. In addition to always having the optimally installed MS codes on various TG machines, this project is expected to benefit MS user community in multiple ways such as (1)gain knowledge about performance (and scaling limitations) of MS codes on various machines, (2) know about the optimal compiler and libraries to use on TG machines, (3) help with justifying resource requests in allocation proposals, (2) efficiently install own version of codes on TG machines etc. This may also help TRAC reviewers cross check users' resource request justification in their allocation proposals.
  • Currently involved in the project: Hang Liu (TACC), Matt McKenzie (LONI), Yang Wang (PSC), Lonnie Crosby (NICS)
  • Following MS researchers were contacted to get their input for this project

Dane Morgan (University of Wisconsin), Blair Tuttle (Penn State), Kyungwha Park (Virginia Tech), Jincheng Du (Univ of North Texas), James Adams, (Arizona State U.), Elizabeth Dickey (Penn State), Will Medlin (University of Colorado), Gautam Ghosh (Northwestern University)

AUS Multi-Core Performance Analysis Advanced Support Project(MCPA ASP)

  • In this project we plan to benchmark multiple codes that have hybrid (MPI-OpenMP/threads) implementations. Our

goal is to compare performance of a hybrid implementation with a straight MPI implementation. It should be noted that as there are more cores per socket, it is expected that there will be less available memory per core. A hybrid implementaion will allow a MPI task to access more memory per core than a straight MPI implementaion and this may have implications on the science being done in a various ways.

  • We are targetting few codes initially:

A benchmark code and an user's astrophysics code from PSC

A astrophysics code from TACC

FFTW threaded code

A user's code looking into fluid structure interaction

A Monte Carlo code from SDSC

  • Currently involved in the project: Raghu Reddy, Nick Nystrom (PSC), Lars Koesterke (TACC), Kwai Wong (NICS),

Kim Dillman (Purdue), Dmitry Pekurovsky, Amit Majumdar (SDSC), Adam Jundt (LONI)
