摘要
Sampled instruction address registers are shared among multiple threads executing on a plurality of processor cores. Each of a plurality of sampled instruction address registers are assigned to a particular thread running for an application on the plurality of processor cores. Each of the sampled instruction address registers are configured by storing in each of the sampled instruction address registers a thread identification of the particular thread in a thread identification field and a processor identification of a particular processor on which the particular thread is running in a processor identification field.
