This document discusses instrumentation and analysis of the NAS Parallel Benchmarks (NPB) application using the Extrae tracing library. It summarizes the tests performed on local and remote machines using 2, 4, 8, 16, and 32 processes. Key metrics like computation time, communication time, load imbalance, and bottlenecks are measured. The analysis shows the NPB application scales well on the remote server but not the local laptop beyond 16 processes due to increased communication and wait times.
