Foil 47 Exploiting Multi-Tier Commodity Software Model

From Java Grande: Role of Java in Large Scale Computations NPACI Summer Institute on Parallel Computing -- August 21 98. by Geoffrey C. Fox
1 Essential idea is consider a three tier model
  • Top tier is the client (in "Network Computer" based 4 tier architectures this becomes 2 tiers)
  • Second tier are servers coordinated by commodity technologies such as the Web and CORBA and communicating via HTTP(Web), IIOP(CORBA), RMI or custom Java sockets.
  • Use middle tier component/container model -- Enterprise Javabeans
  • Third tier are services such as databases, MPP's
2 Preserve the first two tiers as a high functionality commodity information processing system and confine HPCC to the third (lowest) tier.
  • MPI becomes the high performance "machine code" for message passing which you use if HTTP, IIOP or RMI have insufficient performance
