Foil 28 Some Global Computer Architecture Issues

From New CPS615 Foils-- B 28 August 95 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
1 A significant problem is that there is essentially no application software and essentially no machines sold
2 Real World Architectural issue - what problems will produce substantial sales - should optimize for these?
  • So maybe simulation machines will "ride on" commercial database and multimedia server (Web server) markets
  • Historically this created problems as in IBM3090 which was business machine adapted for science and very poor at science
  • Currently SP2 good for science and doing well in Business applications
3 System integration issues
  • Does software allow hardware to realize potential ?
  • Hardware, software reliability
  • (Parallel) I/O for graphics and file access
  • I/O interfaces - HIPPI, FCS, ATM ... ATM most important in real world but HIPPI scientific standard?
