Abstract
A method, system, and/or computer program product for dynamic array masking is provided. Dynamic array masking includes, during execution of computer instructions that access a cache memory, detecting an error condition in a portion of the cache memory. The portion of the cache memory contains an array macro. Dynamic array masking, during the execution of the computer instructions that access a cache memory, further includes dynamically setting mask bits to indicate the error condition in the portion of the cache memory and preventing subsequent writes to the portion of the cache memory in accordance with the dynamically set mask bits. Embodiments also include evicting cache entries from the portion of the cache memory. This evicting can include performing a cache purge operation for the cache entries corresponding to the dynamically set mask bits.
