摘要： 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.

摘要： Techniques for processing a query are provided. One or more operations that are required to process a query are performed by a coprocessor that is separate from a general purpose microprocessor that executes query processing software. The query processing software receives a query, determines one or more operations that are required to be executed to fully process the query, and issues one or more commands to one or more coprocessors that are programmed to perform one of the operations, such as a table scan operation and/or a lookup operation. The query processing software obtains results from the coprocessor(s) and performs one or more additional operations thereon to generate a final result of the query.
