An application is using two COMPSs tasks: one method using dataClay (Task1) objects and another one just for computational reasons (Task2).
To run the application, runcompss command is used with --storage-conf parameter to allow dataClay task to be properly executed. Providing storage-conf means that each worker will call init and finish to connect to dataClay.
We have two nodes, A and B.
dataClay is located in node A, and all COMPSs tasks using dataClay (Task1) are going to node
Node B has no access to dataClay at node A and init and finish calls fail even if the tasks at node B will not use dataClay.
The requested feature is to avoid initializing dataClay at some workers that are not actually using dataClay.
