Pinning Application Threads to Specific Cores Using the Process Lasso Utility

The Process Lasso utility is primarily designed to manage and optimize the CPU usage of running processes on Windows. It also allows you to configure CPU affinity settings for specific applications, ensuring that they run on specific processor cores.

To pin application threads to cores:

  1. Download and install Process Lasso from: https://bitsum.com/
  2. Launch the utility and locate the target application. Using the list of currently running processes, locate the application for which you want to pin threads to specific cores.
  3. Right-click on the target application and choose CPU Affinity.
  4. In the CPU Affinity submenu, you will see a list of available CPU cores. Choose specific cores for the application.
  5. Right-click on the application, navigate to Priority Class, and set the CPU priority for the application to control its access to CPU resources.
Note:After configuring CPU Affinity and the priority, you might need to restart the target application for the changes to take effect.
