Module pyflowTaskWrapper

source code

This script wraps workflow tasks for execution on local or remote hosts. It is responsible for adding log decorations to task's stderr output (which is diverted to a file), and writing task state transition and error information to the wrapper's stderr, which becomes the task's 'signal' file from pyflow's perspective. The signal file is used to determine task exit status, total runtime, and queue->run state transition when pyflow is run in SGE mode.
