Simulation JPA Application Example
Purpose
- This sumulation will serve as a near real world enterprise application that showcases utilizing JPA as the persistence or integration layer - specifically using EclipseLink JPA as the provider.
- This enterprise application will offer the services of a simulated connection machine (Ref: Thinking Machines CM-2) symbolic vector processor.
Goals
- We would like to explore the following limits of the JPA provider and hosting application server.
Infrastructure
- OS: Windows XP or Vista 32/64 bit
- Database: Oracle 11gR1
- JPA provider: EclipseLink 1.2
- JDK: Sun 1.6.0_14
Analysis
Data Model
Processor Architecture
- Each CM-2 processor is composed of up to 64k (65536) 1-bit processors arranged in a 12-dimensional hypercube.
- There are 16 1-bit processors per chip.
- There are 32 processor chips per backplane board
- There are 16 boards per quadrant
- There are 8 quadrands to a CM-2
- There are 16 boards per quadrant
- There are 32 processor chips per backplane board
- We therefore have (2^4=16) x (2^5=32) x (2^4=16) x (2^3=8) = 2^16 = 65536 possible processors in a fully configured system.
- There are 16 1-bit processors per chip.
