Minimizing Data Collection, Result Size, and Execution Time (Memory Access Patterns)

For medium-large targets, several methods are available to minimize the amount of data collected and target execution time. Minimizing the data collected reduces the amount of data you need to examine in the Intel® Advisor Memory Access Patterns Report; it also reduces the size of the generated result. To minimize execution time with the Memory Access Patterns tool, consider reducing the data set processed by the application.

Selecting the Target Application Precisely

Analyzing MPI Workloads

Intel® Advisor allows you to analyze parallel tasks running on a cluster, so you can examine your MPI application for opportunities of adding vectorization or threading parallelism. Use the Intel® MPI gtool with mpiexec to invoke the advixe-cl command and spawn MPI processes across the cluster.

MPI analysis can be performed only through the command line interface, but the result can be viewed through the standalone GUI, as well as the command line.

Pane: Call Stack, Function Node

The Suitability Source window shows you the code where annotations are found. Use the Suitability Source window to view the selected source code to understand its execution paths and data use.

The Call Stack pane shows you the program context in which the annotation was executed, including call sites and loops. The current position on this Call Stack pane is the top-most entry.
