The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.

ARPACK software is capable of solving large scale symmetric, nonsymmetric, and generalized eigenproblems from significant application areas. The software is designed to compute a few (k) eigenvalues with user specified features such as those of largest real part or largest magnitude. Storage requirements are on the order of n*k locations. No auxiliary storage is required. A set of Schur basis vectors for the desired k-dimensional eigen-space is computed which is numerically orthogonal to working precision. Numerically accurate eigenvectors are available on request.

PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It supports MPI, and GPUs through CUDA, HIP or OpenCL, as well as hybrid MPI-GPU parallelism.

Application optimization using FPGAs

A multiscale computational framework for coupling the multiple length scales in chemical vapor deposition (CVD) processes is implemented for studying the effect of the prevailing conditions inside a CVD reactor (macro-scale) on the film growth on a wafer with predefined topography (micro-scale). A multi-parallel method is proposed for accelerating the computations. It combines domain decomposition methods for the macro-scale (reactor scale) model, which is based on partial differential equations (PDEs), and a synchronous master-worker scheme for the parallel computation of the boundary conditions (BCs) for the PDEs; BCs are coming from the micro-scale model describing film growth on the predefined topography.

A set of linear and nonlinear stability analysis tools have been developed to analyze steady state incompressible flows in 3D geometries. The algorithms have been implemented to be scalable to hundreds of parallel processors. The linear stability of steady state flows are determined by calculating the rightmost eigenvalues of the associated generalize eigenvalue problem. Nonlinear stability is studied by bifurcation analysis techniques. The boundaries between desirable and undesirable operating conditions are determined for buoyant flow in the rotating disk CVD reactor.
