METHOD AND SYSTEM FOR SMP PROFILING USING SYNCHRONIZED OR NONSYNCHRONIZED METRIC VARIABLES WITH SUPPORT ACROSS MULTIPLE SYSTEMS

The value of non-discrete metric variables are synchronized at the processor level. When the profiler requests metric information for non-discrete metric variables, the operating system kernel obtains a global value for the requested metric rather than obtaining per-processor metric values for each processor. The global value may be written to trace records. By using a single global per-processor metric for all processors, a single global value of the last metric variable may be used for calculating the resources consumed on all processors since a last recorded event.
