Verification and Validation

Verification is the process of ensuring software is performing its actions correctly. If the software was designed to perform "Task A", say, verification is the process of ensuring the software is, in fact, performing "Task A" correctly. Validation is the process of ensuring that "Task A" is the correct task to be performed in pursuit of the software's goals. To help with this distinction, consider a scientific application that solves multiple complex equations intended to model physics. In this case, verification ensures the software is solving the equations correctly while validation ensures those equations are the correct ones to solve. In fact, scientific software is typically built on models, and the models must be validated, often with experimental data, to be used with confidence. Validation cannot occur without verification, for if the software is not solving the equations correctly, it is impossible to do anything useful with the software. There are multiple methods of performing verification and validation, which are together often referred to as "V&V". Dr. Scott Runnels, owner of Southern Rockies Consulting, LLC, is experienced in developing customized verification approaches for scientific software and integrating those approaches into the software development process. He is experienced in multiple forms of validation, including calibration of scientific software with experimental data.

Training and Education

Southern Rockies Consulting is committed to excellence in education. Dr. Scott Runnels (owner) teaches two courses focused on multi-physics software development at the University of Colorado Boulder, training the next generation in techniques for delivering cost-effective, high quality software products. These are distance learning courses available to your staff under a no-credit option. Syllabi for these courses are found here: Dr. Runnels would be pleased to deliver customized training sessions for your staff on any of the following topics:

Custom Applications

Southern Rockies Consulting provides three customized scientific software computing packages: Mesa, the Sinbad GUI, and CarTherm, which are all examples of light-weight, highly efficient packages developed for specific industry needs. Southern Rockies Consulting also serves as custodian for the custom scientific software package AFFTAC, which is used widely in the railroad industry. Through decades of designing, deploying, and maintaining custom software applications, Dr. Scott Runnels has gained significant experience that can be applied to your specific industry needs. He is also well equipped to develop and apply more general-purpose scientific software solvers, such as finite element/volume or finite difference codes to meet your company's requirements.

High-Performance Computing

With decades of experience working in high-performance scientific software, Dr. Scott Runnels can assist in improving your scientific software's deployment to a high-performance computing ("HPC") environment. Speeding up your current scientific applications, either by better harnessing your desktop resources or porting your software to a supercomputer, is within the experience base and types of services Southern Rockies Consulting offers.

Software Renovation

The process of renovating legacy software requires careful, tedious research of source code in order to gain full understanding its data structures, flow, and the mathematics behind it. Essential tools and methods for software renovation are gained with decades of experience in legacy code development work. Southern Rockies Consulting can apply these tools and methods to your legacy software to bring it up to modern software quality standards of theory, user, and programmer documentation, testing, and version control.
