Dear all, I'm rather new in the use of Kepler and I'm not so expert about actors, directors and so on.
I have the following problem. I have a workflow (with a feedback loop inside) which is being executed a certain number of times depending on the value of a certain variable. When this variable is higher than a predetermined value, the Stop block is called and the workflow ends. I would like to execute a few blocks during the initialization phase, just once, before the execution of my workflow, but I can't. The problem is that these initalizing blocks are called each cycle and not once and, since they are very demanding from a computing-time point of view (access to a database to load signals), the overall execution is slowed a lot. Is anyone aware of a method to have a few blocks called just once, keeping in mind that I am using the SDF director (I put 0 in the Iterations field since, as I said, the overall execution is stopped by the Stop block)? Many thanks in advance for your help Oliviero -------------- next part -------------- An HTML attachment was scrubbed...
