Performance Model
Adjustable parameters in model:
-
time for one 64-bit binary FLOP
-
startup time to send message (latency)
-
startup time to receive message
-
time to send 1 64-bit word
Determine "t"parameters empirically for each computer
Count/estimate/measure FLOP's in code
The model:
Analytical expression in these parameters, processor counts, and problem size parameters
