Abstract
Technical solutions are described for reducing page invalidation broadcasts in a computer system. An example method includes pre-allocating a pool of large memory frames by a real storage manager. The method also includes receiving, by a virtual storage manager, an instruction from an application to allocate a memory buffer, where the instruction includes a request to back the memory buffer using large pages. The virtual storage manager, in response to the instruction, allocates the memory buffer from the pre-allocated pool of large memory frames.
