# Concurrent mode If you are running your build process on the same CI machine, sharing between different builds the same environment, you will need to run the client in concurrent mode using the command line parameter `--concurrent-mode`. In this mode the client will allow different builds to run concurrently on the same environment. Please note that in concurrent mode you cannot execute two phases builds --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
