Message Passing
-
Clearly need buffer management, flow control, protocols etc.
-
But what is appropriate mechanisms -- need to revisit comparison of active messages versus MPI etc.
|
| 2 |
Need to be able to restart separate parts of the (large) hardware independently
|
| 3 |
Need to support performance evaluation with different levels of memory hierarchy exposed
|
| 4 |
Need Storage management and garbage collection
-
PIM micromemory different from hierarchical shared memory
|
| 5 |
Need good job and resource management tools
|
| 6 |
Checkpoint/restart only needed at natural synchoronization points
