FIELD: computing technology.
SUBSTANCE: technical result is achieved by receiving a registration request from a first cache, indicating a specific memory address; and, based on said request, determining whether a cache line corresponding to said memory address is present in said specific second cache, and if the cache line is absent in the specific second cache, one of the following is ensured: calling the registration of said cache line if there is no third cache participating in registration and acting as a backup storage for the second cache, or redirecting said request to the third cache, if there is a third cache; or if the cache line is present in the specific second cache, performing the following: calling the registration of said cache line if the cache line is (i) not determined by said specific second cache as registered, or (ii) determined by said specific second cache as registered, but this specific second cache has not determined that the first cache knows the current value stored in said cache line of the specific second cache; or determining that said cache line is not subject to registration if (i) the cache line is determined by said specific second cache as registered and (ii) the fact that the first cache knows the current value stored in the cache line of the specific second cache is determined.
EFFECT: reduction in the value of the impact of the tracing recording and the size of the tracing file on the productivity.
