For description of B+ Tree, please contact Amittai Aviram who wrote the original serial code, or see the paper listed below.

B+ Tree application has many internal commands that maintain database and process querries. Only J and K commands had enough parallelism to be ported to parallel languages (OpenMP, CUDA, OpenCL). In these implementations, in case of both J and K, the same algorithms (optimized for exposing fine-grained parallelism) were used for fair comparison purposes. For C/OpenMP execution, it is possible to use the original algorithm.
