Example 2: Profiling in MeVisLab

     This example is also available on YouTube.

Introduction

In this example, we are using the MeVisLab Profiler to inspect the memory and CPU consumption of the modules in an example network.

Steps to do

Creating the network to be used for profiling

You can open any network you like, here we are using the example network of the module MinMaxScan for profiling. Add the module MinMaxScan to your workspace, open the example network via right-click and select [ Help → Show Example Network ].

Enable Profiling

Next, enable the MeVisLab Profiler via menu item [ View → Views → Profiling ]. The Profiler is opened in your Views Area but can be detached and dragged over the workspace holding the left mouse button .

Enable profiling by checking Enable in the top left corner of the Profiling window.

Inspect your network

Now open the View2D module’s panel via double-click and scroll through the slices. Inspect the Profiler.

The Profiler shows detailed information about each module in your network.

Field values and their changes for all modules in your network can be inspected in the Fields tab:

In addition to the Profiler window, your modules also provide a tiny bar indicating their current memory and time consumption.

Summary

• Profiling allows you to inspect the behavior of modules and networks including CPU and memory consumption.
• Field value changes can be observed in the Profiler’s Fields tab.
