Well, If that the solution, there is nothing I can do! I'll wait until next version of Kepler for simultaneous GUI execution ! (by the way when new version will come up?)
But as it is said, if I run the workflow without GUI and cache it works: OK! kepler.sh -runwf -nogui -nocache workflow.xml & However in that case parameters cannot be included, like -x 4 -y "foo". I posted also this bug in the email list months ago. Chad Berkley answered: "The problem is that headless kepler uses the MoMLSimpleApplication which does not accept command line params. We're going to add a bug about this and try to get it addressed soon. I'll keep you updated." Any update regarding this problem?
