PARALLEL COMPUTE OFFLOAD TO DATABASE ACCELERATOR

Embodiments herein describe techniques for preparing and executing tasks related to a database query in a database accelerator. In one embodiment, the database accelerator is separate from a host CPU. A database management system (DBMS) can offload tasks corresponding to a database query to the database accelerator. The DBMS can request data from the database relevant to the query and then convert that data into one or more data blocks that are suitable for processing by the database accelerator. In one embodiment, the database accelerator contains individual hardware processing units (PUs) that can process data in parallel or concurrently. In order to process the data concurrently, the data block includes individual PU data blocks that are each intended for a respective PU in the database accelerator.
