[kepler-users] Simultaneous Workflow runnings

[Josep Maria Campanera Alsina]

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?

Thank you very much,

Josep Maria,
