Pliris is an object-oriented interface to a LU solver for dense matrices on parallel platforms. These matrices are double precision real matrices distributed on a parallel machine.

The Rapid Optimization Library (ROL) is a package for large-scale optimization. It is used for the solution of optimal design, optimal control and inverse problems in large-scale engineering applications. Other uses include mesh optimization and image processing.

RTOp (reduction/transformation operators) provides the basic mechanism for implementing vector operations in a flexible and efficient manner.

similar to md5sum and sha256sum.

This package contains the INDI driver for Radio Astronomy Supplies SpectraCyber hydrogen line spectrometer.

Rythmos is a transient integrator for ordinary differential equations and differential-algebraic equations with support for explicit, implicit, one-step and multi-step algorithms. The fundamental design of Rythmos is aimed at supporting operator-split algorithms, multi-physics applications, block linear algebra, and adjoint integration.
