    Abstract: Nodes in a distributed node system are configured to support memory corruption detection when memory is shared between the nodes. Nodes in the distributed node system share data in units of memory referred to herein as “shared cache lines.” A node associates a version value with data in a shared cache line. The version value and data may be stored in a shared cache line in the node's main memory. When the node performs a memory operation, it can use the version value to determine whether memory corruption has occurred. For example, a pointer may be associated with a version value. When the pointer is used to access memory, the version value of the pointer may indicate the expected version value at the memory location. If the version values do not match, then memory corruption has occurred.

    Abstract translation: 分布式节点系统中的节点被配置为在节点之间共享存储器时支持内存损坏检测。 分布式节点系统中的节点以这里称为“共享高速缓存行”的存储器单元共享数据。节点将版本值与共享高速缓存行中的数据相关联。 版本值和数据可以存储在节点的主存储器中的共享高速缓存行中。 当节点执行内存操作时，它可以使用版本值来确定是否发生内存损坏。 例如，指针可能与版本值相关联。 当指针用于访问存储器时，指针的版本值可以指示存储器位置处的期望版本值。 如果版本值不匹配，则会发生内存损坏。

    Abstract: Systems and methods for utilizing memory version instructions and techniques in conjunction with garbage collection in a processor. A hardware-assisted garbage collection algorithm may be executed by a computing system to move live objects between memory regions. Special store instructions may be utilized to mark the live objects of each memory region that is about to be migrated. Mutators performing useful work may be configured to trap on a memory region which is marked for migration.

    Abstract: Techniques for executing versioned memory access instructions. In one embodiment, a processor is configured to execute versioned store instructions of a first thread within a first mode of operation. In this embodiment, in the first mode of operation, the processor is configured to retire a versioned store instruction only after a version comparison has been performed for the versioned store instruction. In this embodiment the processor is configured to suppress retirement of instructions in the first thread that are younger than an oldest versioned store instruction until the oldest versioned store instruction has retired. In some embodiments, the processor is configured to execute versioned store instructions of a given thread within a second mode of operation, in which the processor is configured to retire outstanding versioned store instructions before a version comparison has been performed.

    Abstract: Techniques for handling version information using a copy engine. In one embodiment, an apparatus comprises a copy engine configured to perform one or more operations associated with a block memory operation in response to a command. Examples of block memory operations may include copy, clear, move, and/or compress operations. In one embodiment, the copy engine is configured to handle version information associated with the block memory operation based on the command. The one or more operations may include operating on data in a cache and/or modifying entries in a memory. In one embodiment, the copy engine is configured to compare version information in the command with stored version information. The copy engine may overwrite or preserve version information based on the command. The copy engine may be a coprocessing element. The copy engine may be configured to maintain coherency with other copy engines and/or processing elements.
