Effects of VLSI on Early MIMD Machines
Single chip processors spawned flury of design in nonshared memory domain
- ZMOB, ring of 30, 8-bit procs, Maryland
- Pringle, 8x8 config mesh, 8-bit procs, Purdue CS
- Cosmic Cube, 6-cube, 16-bit procs, Caltech -- Intel commercialized this as iPSC, iPSC/2
Quickly, 32-bit MIMD machines arrived
- Sequent sold an elegant shared bus machine
- BBN Butterfly was a large shared memory machine
- Two different approaches to choherency
