Foil 46 Architectures for High Performance Computers - II

From Variety of Foils Used Starting January 97 General -- 1997. by Geoffrey C. Fox *

Metacomputers are a very important trend which uses similar software and algorithms to conventional "MPP's" but have typically less optimized parameters
  • In particular network latency is higher and bandwidth is lower for an informal HPC
  • Latency is time for zero length communication -- start up time
Formal high performance computers are the classic (basic) object of study and are
"closely coupled" specially designed collections of compute nodes which have (in principle) been carefully optimized and balanced in the areas of
  • Processor (computer) nodes
  • Communication (internal) Network
  • Linkage of Memory and Processors
  • I/O (external network) capabilities
  • Overall Control or Synchronization Structure
