Abstract: The embodiments relate to a method for managing a garbage collection process. The method includes executing a garbage collection process on a memory block of user address space. A load instruction is run. Running the load instruction includes loading content of a storage location into a processor. The loaded content corresponds to a memory address. It is determined if the garbage collection process is being executed at the memory address. The load instruction is diverted to a process to move an object at the memory address to a location outside of the memory block in response to determining that the garbage collection process is being executed at the first memory address. The load instruction is continued in response to determining that the garbage collection process is not being executed at the memory address.

Abstract: A computer-implemented method for identification of cache memory transiency may include identifying, with a processor, a virtual memory address section having a virtual memory address, determining, via the processor, a classification of cache memory transiency of the virtual memory address section, and determining, with the processor, based on the classification of cache memory transiency, a cache exemption status.

Abstract: The embodiments relate to a computer system, computer program product and method for managing a garbage collection process. Processing control is obtained based on execution of a load instruction and a determination that an object pointer to be loaded indicates a location within a selected portion of memory undergoing a garbage collection process. The determination includes identifying a base address and size of a first memory block subject to the garbage collection, subdividing the first memory block into sections, assigning a binary value to each section, and determining if the first memory block corresponds to the enabled section. An image of the load instruction is obtained and a pointer address is calculated from the image. The object pointer is read and it is determined whether the object pointer is to be modified. The object pointer is modified and stored in a selected location.
