More detailed Comments - II

• In resource material at end, we define 3 basic tiers

  • client, (Grande)Gateway and backend (Grandecomputer)

• Sandia CPLANT machines would appear in both gateway and backend tiers

  • In gateway, one would use full NT (or perhaps Linux environments) and in backend, systems optimized for performance
  • High end gateway machines would be typical large SMP’s
  • Commodity protocols would link both UNIX and NT -- HPCC backend systems could be specialized

• As described in following, we suggest gateway can be viewed as linked servers -- each hosting some sort of service -- and linked either by user-set, agent negotiated or fixed channels

• Sun’s new JINI resource management system seems possibly very important
