Tech-X develops a variety of scientific software, including physics simulation software and high-performance computing libraries.
Simulation and Modeling Tools
VSim is a framework that uses PIC (Particle-in-Cell) methods to model particles, so it allows you to simulate the kinetic behavior of particles as well as electromagnetic phenomena. Because VSim supports massively parallel computing that scales to tens of thousands of processor cores, you are able to model complex geometries and more physical phenomena while still obtaining results within a reasonable amount of elapsed time.
VSim Packages
VSim packages are a field-specific and economical alternative the full VSim PIC simulation tool.
General purpose, high resolution shock capturing methods for fluid plasma modeling. Advanced fluid, plasma and electromagnetic modeling on unstructured meshes. The USimComposer GUI enables simulation validation, execution, and visualization in one application.
USim Packages
Individual USim packages are available for Basic Simulations, Hypersonics, and High Energy Density Plasmas.
PSim is an object-oriented framework that simulates phase morphologies of dense block copolymers melt systems.
PSim quickly solves the numerical self-consistent field theory (SCFT) equations for modeling copolymers. The SCFT algorithm is rigorous method for coarse-graining models of complex block copolymer mixtures such that sufficient detail is retained to describe the novel morphologies these materials form when they undergo phase segregation. This coarse-graining procedure allows researchers to study block copolymer structure in simulations that can run much faster than more explicit methods such as classical all-atom molecular dynamics.
High-performance Computing Libraries
GPULib Enables users to access high performance computing with minimal modification to their existing programs.
By providing bindings between Interactive Data Language (IDL) and large function libraries, GPULib can accelerate new applications or be incorporated into existing applications with minimal effort. No knowledge of GPU programming or memory management is required.
GPULib is built on top of NVIDIA's Compute Unified Device Architecture (CUDA) platform. CUDA is supported by a wide range of NVIDIA products, including GeForce, Quadro, and Tesla cards.
Coming soon... PTSolve and GELUS
PTSolve is the Tech-X-supported Portable, Extensible Toolkit for Scientific Computation. The PTSolve bundled PETSc package is both easier to install and easier to use than PETSc. Tech-X has packaged PTSolve for Windows, Mac OS X, and Linux platforms with 3 different FORTRAN compilers. PTSolve is supported by Tech-X Corporation.
GELUS is a library of GPU-accelerated preconditioner methods for the sparse triangular solve family of algorithms that includes incomplete factorization and stationary methods. GELUS substantially accelerates the performance of Krylov Iterative Methods by providing targeted performance improvements in the rate-limiting preconditioner solve.
