Case Study: STFC Daresbury Laboratory achieves faster, higher-quality software development with Rogue Wave Software's TotalView

High-Quality Debugging Capabilities Help STFC Daresbury Laboratory Simplify and Shorten Software Development

STFC Daresbury Laboratory, a UK research facility supporting scientists with high-end supercomputing (including IBM Blue Gene/P), faced the challenge of developing, debugging and optimizing complex large-scale parallel applications and understanding data flows across many cores. To address the need for reliable, state-of-the-art debugging and analysis tools, STFC selected Rogue Wave Software’s TotalView to support developers working on everything from computational chemistry to CFD and ocean/atmospheric simulations.

Rogue Wave Software implemented TotalView’s interactive parallel debugger and multi-dimensional data array viewer, replacing slow compile‑run‑print cycles and command-line debugging. The result was reduced software development time, improved software quality, resolution of a numerical stability problem that was hard to isolate, and better scaling and performance on tens of thousands of cores—boosting STFC Daresbury Laboratory’s developer productivity, competitiveness, and future project opportunities.
