Various talks on the ExMatEx project that have been presented to external audiences.
The following talks were presented as part of the ExMatEx proxy app Deep Dive session. The conference was held in Arlington, Virginia, October 1-3, 2012.
-
Overview of ExMatEx Proxy Applications [PDF], David Richards, Lawerence Livermore National Laboratory, LLNL-PRES-585773.
-
CoDesign Molecular Dynamics (CoMD) Proxy App [PDF], Jamal Mohd-Yusof, Los Alamos National Laboratory, LA-UR-12-25066.
A brief overview of the the class of physics problems targeted is presented, followed by the computational considerations at both the machine and node level. Then we cover the original application (SPaSM) from which the mini-app was extracted, along twith the equations being solved. The implementations of the various versions (OpenCL, CUDA, Intel MIC) of the proy app are discussed, along with some performance metrics. In situ visualization is then briefly discussed. Modeling of the proxy app in Aspen is presented along with some preliminary results. Finally, the status of the mini-app is summarize and plan for future enhancements are presented.
