Objectives

This workshop is aimed at taking stock of the funded collaborative interdisciplinary research projects which the Parallel Programming Laboratory (the developers of Charm++ and AMPI) are engaged in.

In addition to the computer scientists at PPL, the collaborators represented at this workshop include those from:

  • University of Illinois at Urbana Champaign (CS, ME, TAM, MS, Physics, Beckman)
  • University of Washington, Seattle.
  • Princeton University
  • NYU
  • IBM
  • PSC (Pittsburgh Supercomputing Center)

The interdisciplinary projects represented are:

  • NIH: Parallel Scalable Molecular Dynamics: NAMD (With Klaus Schulten, Bob Skeel)
  • DOE: Rocket Simulation (CSAR, director: Michael Heath)
  • NSF: Material Simulation (CPSD: with Robert Haber, Jonathan Dantzig, Duane Johnson)
  • NSF: Computational Cosmology Simulations (With Tom Quinn)
  • NASA: Scalable Visualizations for Computational Cosmology (With Tom Quinn)
  • NSF: Quantum Mechanical and classical modeling (QM/MM) (Roberto Car, Mike Klein, Josep Toerrellas, Glenn Martyna, Mark Tuckerman, Nick Nystrom)
  • NSF: Programming Environments for Blue Gene Supercomputer and Applications (with S. Adve, D. Padua, P. Geubelle)

Registration

Hotel

We have reserved a block of rooms at the Chancellor Hotel for the Charm++ workshop. Participants need to call the Chancellor Hotel by 5th October, 02 to reserve a room. (Phone: 1-800-257-6667.) Refer to the rooms for "CHARM Workshop".

Schedule:

(may change slightly)

(All talks and tutorials are open to the public.)

Oct 9

The morning sessions will all run simultaneously:

    • 9:15am-10:00am Breakfast in 2240 DCL (for registered participants)
    • 10am-noon: Charm++ tutorial in 2240 DCL (Sindhura Bandhakavi) [PowerPoint]
      This hands-on tutorial will give a basic introduction to Charm++ for people who have never written a Charm++ program. It will cover the basic virtualization concept, proxies, and basic uses of arrays.

    • 10am-noon: AMPI tutorial in 2261 DCL (Chao Huang) [PowerPoint] [PDF]
      This hands-on tutorial will give a basic introduction to AMPI, our adaptive version of MPI on top of Charm++. Some familiarity with MPI is assumed. It will cover the major differences between MPI and AMPI, and discuss threadsafety issues like global variables.


The afternoon sessions also run simultaneously:

 

    • 2pm-4pm: FEM framework tutorial in 2240 DCL (Gunavardan Kakulapati) Basics [PowerPoint] Advanced [PowerPoint]
      This tutorial will give a basic introduction to the Charm++ Finite-Element Framework (FEM Framework). It will cover the concepts and major functions of the FEM framework, and show how to convert a serial FEM program into a parallel FEM program running in the framework. Its coverage will be much the same as that of the FEM Workshop.
    • Discussions on Quantum Simulation in 2508 DCL.

Oct 10

The formal workshop begins in 2240 DCL. The morning session will consist of talks followed by a discussion session:


After a break for lunch, the afternoon session includes:

    • 1:30-2:00pm: Faucets: Efficient Utilization of Multiple Clusters (Jay DeSouza) [PowerPoint]
    • 2:00-2:30pm: CSAR and Multi-component simulations (Orion Lawlor) [PowerPoint]
    • 2:30-3:00pm: Unstructured Grid applications in material process simulation (Jon Dantzig, Mechanical Engineering)
    • 3:30-4:30pm: Parallel Quantum Dynamics (Roberto Car, Glenn Martyna, Mark Tuckerman, Ramkumar Vadali [PowerPoint])
    • Discussion and conclusion


A formal banquet will follow the talks at the Silvercreek Restaurant in the Greenhouse room, starting at 6:30 pm. (for registered participants)

Dinner choices will be Fusilli Primavera (vegetarian) and Apple Amaretto Chicken--we will need your choice by Monday, October 4. Dinner will include soup or salad, beverage, vegetable, rice, and fresh baked breads. For dessert, we will have a small dessert buffet where guests can have either chocolate layer cake or mountain berry flan tart... or a little of both. There will be a cash bar.


October 11

The morning sessions will run simultaneously:

    • 9:15am-10:00am Breakfast in 2240 DCL (for registered participants)
    • 10am-noon: Clusters tutorial in 2240 DCL (Jay DeSouza and Sameer Kumar) [PowerPoint] installation files
      This tutorial will provide a basic introduction to the clustering technology provided by Charm++, and demonstrate how that technology can improve cluster utilization.
