In a October 27 blog post, Ryan Haveson, a group program manager on the User Experience team, offered a glimpse of update on Task Manager in Windows 8, since the Windows Developer Preview.

Specifically, Haveson talks about the enhancements made to the Task Manager tools for managing systems with a large number of logical processors. "The new Task Manager will sport new capabilities in Windows 8 Beta compared to the Developer Preview release, streamlining management in excess of 64 logical processors, according to Ryan Haveson, a group program manager on the User Experience team," revealed Haveson.

"This is scalability well beyond desktop PCs, and is designed for the server and data center. A big part of Windows development is that the OS scales across a wide range of form factors and CPU architectures," said Haveson. Adding, he said "Customers with machines leveraging multiple processors will be able to use Task Manager in order to associate a specific process with the CPU they want. This can be done by locating the process in the list under the Details Tab, and selecting 'Set affinity' from the right-click contextual menu."

The evolution of Task Manager better equipped the tool to help server administrators and customers using mega-PCs to deal with large number of logical processors, no less than 160 in the particular case highlighted by Haveson.

Enhancements in Windows 8 Beta Task Manager come to make it easier for users to compare CPU real-time usage, deliver a better view over processor activity and making it easier to find the chip ID.

In the screen shots below, taken from a current build of Windows 8, it is now easy to see all the logical processors at a glance and know which are being utilized to high and low capacity.

"In the new CPU graph, you can also get the logical processor ID that maps to each entry via a tooltip, by hovering over the entry with the mouse."

"A major benefit of a heat map is that it scales really well to large data sets. The new Task Manager will show as many logical processors as the OS supports."
