I make use of cromwell in server mode to execute bioinformatics data processing pipelines written in widdle (.wdl = workflow description language). The machine from which I submit workflows is not the same as the machine that hosts the cromwell server (so a remote cromwell server). The input files for the workflow I want to submit are stored on the machine from which I submit, and they need to be available on the cromwell server machine? Should I first copy my files and then submit the workflow? Or is there a way to submit the workflow and let cromwell automatically copy the input files over?
