Processes and cores window

The Processes and Cores window enables you to change the number of cores per process.

Most modern CPUs support hyperthreading and report multiple logical cores for each physical core. Some programs run faster when scheduling threads or processes to use these hyperthreaded cores, while most HPC codes run more slowly. Rather than show all of the sparklines at half-height simply because the hyperthreaded cores are (wisely) not being used, Linaro MAP tries to detect this situation and will rescale its expectations to the number of physical cores used by your program.

If this goes wrong for any reason, you will see large portions of unusual colors in your sparklines and the application activity chart (for example, bright red). When that happens, open this dialog and increase the cores per process value.

To open this dialog use the View ‣ Processes and Cores menu option, or click the X cores (Y per process) hyperlinked text in the application details section above the metric graphs.
