Abstract
We present the design and evaluation of a Datalog engine for execution
in Graphics Processing Units (GPUs). The engine evaluates recursive
and non-recursive Datalog queries using a bottom-up approach based on
typical relational operators. It includes a memory management scheme
that automatically swaps data between memory in the host platform (a
multicore) and memory in the GPU in order to reduce the number of
memory transfers.
To evaluate the performance of the engine, three Datalog queries were
run on the engine and on a single CPU in the multicore host. One query
runs up to 200 times faster on the (GPU) engine than on the CPU.
