Profiling the workflow on AWS

Running Breeze on the new workflow on AWS allows you to see the architecture changes. The AMI has the Xilinx tool installation and the top-level workflow script needed to start the workflow. This script calls the AWS CLI (pre-installed with the image) to pull the project data from S3 object storage. The workflow is then run using a local instance store.

The following figure shows the new timeline with the calls to the AWS CLI. Breeze shows you I/O statistics and the dependencies for each process in the workflow. In the left pane, the view shows the entire workflow; and in the right pane, the view shows a detailed breakdown of what the AWS CLI is doing. You can see the connections to the object storage.
