Original Abstract Submitted

A computer-implemented method, according to one embodiment, includes determining that a first predetermined pattern is to be written to a first cache line of a cache. In response to the determination, a first bit is set in a first directory instead of writing the first predetermined pattern in the first cache line. The first bit is associated with the first cache line in the first directory. A computer program product, according to another embodiment, includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and/or executable by a computer to cause the computer to perform the foregoing method. A system, according to another embodiment, includes a processor, and logic integrated with the processor, executable by the processor, or integrated with and executable by the processor. The logic is configured to perform the foregoing method.
