NWChem

  No analysis available

NWChem aims to provide its users with computational chemistry tools that are scalable both in their ability to treat large scientific computational chemistry problems efficiently, and in their use of available parallel computing resources from high-performance parallel supercomputers to conventional workstation clusters.

MADNESS provides a high-level environment for the solution of integral and differential equations in many dimensions using adaptive, fast methods with guaranteed precision based on multi-resolution analysis and novel separated representations. There are three main components to MADNESS. At the ... [More] lowest level is a new petascale parallel programming environment that increases programmer productivity and code performance/scalability while maintaining backward compatibility with current programming tools such as MPI and Global Arrays. The numerical capabilities built upon the parallel tools provide a high-level environment for composing and solving numerical problems in many (1-6+) dimensions. Finally, built upon the numerical tools are new applications with initial focus upon chemistry, atomic and molecular physics, material science, and nuclear structure. Please look in the wiki for more information and project activity. Getting the sourceAnonymous, read-only source checkout: svn checkout http://m-a-d-n-e-s-s.googlecode.com/svn/local/trunk m-a-d-n-e-s-s-read-onlyDevelopers, please see the wiki Subversion page for instructions. Underneath the hoodIf you would like a glimpse at what's going on under the hood have a look at this call graph generated using the Google perftools. It nicely shows how work is funneled through the task-queue and how about 50% of the time is spent in the optimized matrix routines. The calculation computed the energy and gradient for di-nitrogen using the local density approximation on a two-core Thinkpad x61t.

This is a very preliminary version of a code generator for tensor transposes. The intended application is the coupled-cluster codes in NWChem, but any related program which does quantum many-body computations may benefit from it. It will be some time before I attempt to make this code useful for ... [More] anyone else. That means there is no technical support and no documentation, nor do I even expect this code to work for you. Jeff Hammond, July 2008 This repository also includes Fettuccine (Fast thrEaded Tensor Transposes Using C and Cuda In Nvidia devicEs), which is a combined effort by Tom Henretty (OSU) and myself. Jeff Hammond, August 2008 While I'm far from finished with the transpose library, I'm starting to work on true native-dimension tensor contractions instead of transpose-transpose-dgemm-transpose. Consistent with the theme, this library is going to be called Macaroni (Multidimensional Array Contraction...) Jeff Hammond, September 2008 [Less]
