[kepler-users] Simultaneous Workflow runnings

[Jianwu Wang]

Hi Christopher,

    Thanks for your explanation. I'm more aware about the request on 
multiple Kepler processes. Currently, maybe different user roles on the 
same machine is feasible way, though it has a few small exceptions 
(http://bugzilla.ecoinformatics.org/show_bug.cgi?id=3694).

    In my understanding and experience, users can't start another Kepler 
process when there are another running one. But Josep did opened another 
workflow: "the new workflow shows the wrapping up message without
executing the workflow. ". So I guess he used 'File-->Open File' to open 
the second workflow. If so, the exception is not about multiple Kepler 
processes, but job related actors.

Best wishes

Sincerely yours
