Scalability Analysis

When designing a parallel application, you need to know if the application performance continues to increase when you add more threads or tapers off. However, in a complex application, it is often not obvious what the overall parallelism of the application is.

Use the scalability analysis plugin to:

  • Estimate the application parallelism provided by the topology of the graph.

  • Estimate the inherent application parallelism provided within nodes that have unlimited concurrency.

  • Identify contributing factors to overall parallelism.

The scalability analysis plugin allows you to run a graph with a varying number of threads and provides speedup information of the graph with respect to running the graph serially. You can specify any configuration of the graph to help design and analyze the graph.
