You can access information about current CPU configuration through the vSphere Client or using the vSphere SDK.
Launch the vSphere Client and log in to a vCenter Server system.
- In the vSphere Client, select the host and click the Configuration tab.
- Select Processors.
You can view the information about the number and type of physical processors and the number of logical processors.Note: In hyperthreaded systems, each hardware thread is a logical processor. For example, a dual-core processor with hyperthreading enabled has two cores and four logical processors.
- (Optional) You can also disable or enable hyperthreading by clicking Properties.
