Pareon tool smooths multicore software optimization

The Pareon development tool from Vector Fabrics allows software developers to optimize their applications for multicore systems in hours or days, a task that typically takes weeks or months to complete. The tool’s analysis engine prevents hard-to-find and hard-to-reproduce threading bugs, while its hardware modelling engine prevents the developer from writing code that introduces performance bottlenecks or even causes slowdowns.

Pareon combines the features of Vector Fabrics’ previous vfEmbedded and vfThreaded-X86 parallelization tools into one product. In addition, Pareon incorporates over 50 new features, including bus and shared cache contention modelling, support for C/C++, ARM Neon, and recognizing many more parallel code patterns. Whereas Vector Fabrics’ previous tools were cloud-based and ran in the user’s web browser, Pareon runs locally on a workstation, integrating more closely with typical development workflows that include complex build mechanisms, and targets large applications that rely heavily on calling routines inside binary libraries.

Pareon follows a three-step process that turns a sequential program into a parallelized, faster implementation:

  1. Insight: Pareon analyzes and runs the program on a model of the multicore hardware, and then presents intuitive program visualizations that give the developer keen insight into the program’s execution, internal dependencies, and memory behaviour. This allows developers to focus on memory bottlenecks and compute bottlenecks right from the start.
  2. Investigate: Using a point-and-click interface, the developer adds parallelism where it has the biggest impact on performance. Code constructs that prevent parallelism are identified so that they can be removed. Pareon shows the impact of the parallelization on program performance, taking into account the multiple processors, memory and cache bottlenecks, synchronization and communication, and thread scheduling overhead.
  3. Implement: After selecting the best parallelization strategy in the investigation phase, Pareon outlines detailed and straightforward code refactoring steps that implement the parallel constructs. This keeps the developer in control of the parallel code while eliminating the risk of introducing hard-to-detect and correct bugs.
