Parallel Main-Memory Indexing for Moving-Object Query and Update Workloads

Summary: PGrid—an in-memory grid index for moving objects—exploits multi-core parallelism to handle high-rate workloads. Updates and queries share a single data structure, avoiding snapshots; hardware-assisted atomic updates with object-level copying implement non-divisible updates, delivering fresh results and near-linear scalability.
