Abstract:
1. A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to: monitor a set of activity values associated with a set of functional units; monitor a set of thermal levels associated with the set of functional units; for a current activity value associated with the functional unit in the set of functional units, determine whether a thermal level associated with the functional unit differs from a verified thermal level beyond a predetermined threshold, wherein the verified thermal level for the functional unit is identified from a covariance matrix that associates activity values of the functional unit with verified thermal levels for the functional unit; and responsive to the thermal level associated with the functional unit differing from the verified thermal level beyond the predetermined threshold, send an indication of suspected abnormal activity associated with the given functional unit.
