Introduction

Transformative discovery in computational nanoscience, advanced materials, and energy research requires breakthroughs in theoretical models, algorithms, and software capable of using multicore chips and accelerator hardware such as graphics processing units (GPUs) or similar devices.  This conference seeks to bring together computationally oriented scientists interested in using accelerator coprocessors in electronic structure theory. We will discuss recent advances, barriers, and perspectives in modeling electronic structure on accelerators.[1]

We expect talks from speakers representing industry (Nvidia, Intel, Cray, and PGI) end developers of several electronic structure packages (BigDFT, NWChem, Gamess, ACES III, TeraChem, QMC Pack, Quantum Espresso, Madness).

[1] NSF report of Advisory Committee for CyberInfrastructure Task Force on “Software for Science and Engineering,” March , 2011

Purpose:

  • To discuss difficulties in developing and using electronic structure methods on accelerators such as GPUs and Intel’s MICs
  • To establish multidisciplinary and interdisciplinary teams and research collaborations to overcome challenges in electronic structure on accelerators
  • To highlight new algorithms and methods for hardware-accelerated electronic structure codes
  • On-site training to BigDFT code

You can read more about this workshop here.

BigDFT Tutorial:

This workshop will include a science session and a hands-on training session for the GPU-based BigDFT program. BigDFT is a free software code implementation for full electronic structure calculation with a formalism based on Daubechies wavelets in hybrid parallel architectures with graphics processing units (GPUs). Daubechies wavelets formalism has proven useful in benefitting from hardware accelerators and its implementation on BigDFT was awarded the 2009 French Bull-Fourier prize.

Poster Session

There will be a poster session on Monday night. Poster should present any HPC and electronic structure related work, such as:  (a) application of electronic structure, or (b) effort of code porting to hardware accelerator, or (c) new methods and algorithms being developed.  We want to learn about your work!

There will be a prize given out for the best poster. Nvidia has donated a Tesla Card C2075 which will be awarded to the Best Poster Winner. Details of this prize can be found here.

Financial Support:

This is a joint workshop between ORNL’s and the University of Tennessee’s Joint Institute for Computational Sciences and is in part supported by EPSCoR’s Cyberinfrastructure RII “A Desktop to TeraGrid Ecosystem” (NSF EPS-0919436) project.
