Tolong jelaskan mengenai GPGPU Graph Processing dari Graph database

Medusa  - A framework for graph processing using Graphics Processing Units (GPUs) on both shared memory and distributed environments. Medusa allows users with no GPU programming expertise to leverage GPUs for graph processing.

APIs and Graph Query/Programming Languages

Bounds Language  - terse C-style syntax which initiates concurrent traversals in GraphBase and supports interaction between them.

Blueprints  - a Java API for Property Graphs from TinkerPop  and supported by a few graph database vendors.

Blueprints.NET  - a C#/.NET API for generic Property Graphs.

Bulbflow  - a Python persistence framework for Rexster, Titan, and Neo4j Server.

Cypher Query Language  - a declarative graph query language for Neo4j that enables ad hoc as well as programmatic (SQL-like) access to the graph

Gremlin  - an open-source graph programming language that works over various graph database systems.

Neo4jClient  - a .NET client for accessing Neo4j.

Neography  - a thin Ruby wrapper that provides access to Neo4j via REST.

Neo4jPHP  - a PHP library wrapping the Neo4j graph database.

NodeNeo4j  - a Node.js driver for Neo4j that provides access to Neo4j via REST

Pacer  - a Ruby dialect/implementation of the Gremlin graph traversal language.

Pipes  - a lazy dataflow framework written in Java that forms the foundation for various property graph traversal languages.

Pixy  - a declarative graph query language that works on any Blueprints-compatible graph database

PYBlueprints  - a Python API for Property Graphs.

Pygr  - a Python API for large-scale analysis of biological sequences and genomes, with alignments represented as graphs.

Rexster  - a graph database server that provides a REST or binary protocol API (RexPro). Supports Titan, Neo4j, OrientDB, Dex, and any TinkerPop/Blueprints-enabled graph.

RDFSharp  - a .NET API for modeling RDF graphs, storing them on many SQL databases (Firebird, MySQL, PostgreSQL, SQL Server, SQLite) and querying them with SPARQL.

SPARQL - a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework format.

SPASQL  - an extension of the SQL standard, allowing execution of SPARQL queries within SQL statements, typically by treating them as subquery or function clauses. This also allows SPARQL queries to be issued through "traditional" data access APIs (ODBC, JDBC, OLE DB, ADO.NET, etc.)

Spring Data Neo4j  - an extension to Spring Data  (part of the Spring Framework), providing direct/native access to Neo4j

Oracle SQL and PL/SQL APIs  - have graph extensions for Oracle Spatial and Graph.

Styx (previously named Pipes.Net) - a data flow framework for C#/.NET for processing generic graphs and Property Graphs.

Thunderdome  - a Titan Rexster Object-Graph Mapper for Python (no longer maintained)

Mogwai  - a Titan Rexster Object-Graph Mapper for Python - Forked from Thunderdome

Rexpro-Python  - a Titan Rexpro connection handler for Python.
