| • | COMA:
cache-only memory architecture |
|||||||||||||||
| – | Data
migrates into local DRAM of CPUs where it |
|||||||||||||||
| is
being used |
||||||||||||||||
| – | Handles
very large working sets cleanly |
|||||||||||||||
| – | Replacement
from DRAM is messy: have to make |
|||||||||||||||
| sure someone
still has a copy |
||||||||||||||||
| – | Scope
for interesting OS/architecture hybrid |
|||||||||||||||
| – | System
slows down if total memory requirement |
|||||||||||||||
| approaches
RAM available, since space for |
||||||||||||||||
| replication
is reduced |
||||||||||||||||
| • | Examples:
DDM, KSR-1/2, rumours from |
|||||||||||||||
| IBM… |
