Case Study: CAS Group cuts development time up to 70%, reduces costs 40% and boosts reliability with Rogue Wave Software’s TotalView

Debugger on Target for Complex Simulation Environment Requirements

CAS Group, part of Wyle, needed a robust debugger to support a five-year DoD contract for air and missile defense modeling and simulation. Their codebase included legacy Fortran and other languages ported to C++, ran on multiple high-performance Linux platforms, and required compatibility with the Intel® Compiler and strong multi-threaded debugging capabilities — a set of constraints that few tools met.

Rogue Wave Software’s TotalView was deployed to meet these requirements, providing precise thread control, cross-platform visibility, and support for Intel® Compiler-optimized builds so CAS Group could port and test legacy code side-by-side. The solution cut development time by 60–70%, reduced tooling costs by about 40% by avoiding multiple debuggers, and improved software reliability by more than 50%, enabling faster, more reliable delivery of mission-critical simulations.
