Detailed Description

Google Test Unit Tests for the kernels associated with the Random Ball Cover data structure.

Note

Use the --profiling flag to enable profiling of the kernels.

The benchmarks in these tests are against naive CPU implementations of the associated algorithms. They are used only for testing purposes, and not for examining the performance of their GPU alternatives.
