Hello mailto:amit.singh4@honeywell.com amit.singh4@honeywell.com,

 

 

Thank you for posting on the Intel ® communities.

 

 

In order to best assist you, I will need to know the exact model of the system where the processor is, this is so that we can have more information and provide you with the most accurate response, also, keep in mind that we ( Intel ® ) do not have such a tool, however, the manufacturer of your system may.

Hi,

We are using the Intel Centerton S1240 processor for our product and currently evaluating the processor form single core OS environment to multicore OS environment.

As the Centerton S1240 has both core having individual L2 cache of 512KB, so for my evaluation I want to measure the Snooping impact from one core to other in terms of execution performance and is there a way in software to control the snooping by processor by doing some register settings, as my current product may use each core and single processor without sharing the data or threads between the core.

Regards

Amit
