Simulating Ideal Communication
Use the Idealization capability to understand application imbalance and estimate a potential application speedup after MPI implementation tuning and/or network upgrades.
The idealizer creates the ideal communication environment from the real trace generated by the Intel® Trace Collector. To simulate the application behavior in the ideal communication environment, select Advanced > Idealization.
Idealization assumes the following conditions at trace processing time:
zero network latency
infinite network bandwidth
zero buffer copy time
infinite buffer size
Idealization assumes concurrency as a limitation factor. For example:
a message cannot be received before it is sent
an All-To-All collective operation ends when the last thread starts
