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

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
