Preventing the Reading and Writing of Checkpoint Files

Preventing the reading and writing of checkpoint files

When performing batch (non-interactive) post-processing, for example driven by FAST-TCF or REPORTER, you are relying on running scripts of commands that assume a given programme state. These can be upset if checkpoint files exist on disk since they will have no mechanism for dealing with them.

Therefore the environment variable SUPPRESS_CHECKPOINT may be set, with the following result:

• Any existing checkpoint files will be ignored, and no questions asked about them
• No checkpoint file will be written during this session.

This and other environment variables are explained in The Following Environment Variables may be Used to Control the Behaviour of D3PLOT .
