Abstract
Various embodiments are generally directed to detecting race conditions arising from uncoordinated data accesses by different portions of an application routine by detecting occurrences of a selected cache event associated with such accesses. An apparatus includes a processor component; a trigger component for execution by the processor component to configure a monitoring unit of the processor component to detect a cache event associated with a race condition between accesses to a piece of data and to capture an indication of a state of the processor component to generate monitoring data in response to an occurrence of the cache event; and a counter component for execution by the processor component to configure a counter of the monitoring unit to enable capture of the indication of the state of the processor component at a frequency less than every occurrence of the cache event. Other embodiments are described and claimed.
