Hello, I have been able to write my own CGF example, composed of three nodes cascade connected (one output is connected to the previous node’s input) and managed to run it successfully.

However, I noticed that once i launch my CGF example, each time a node is called, both the SETUP and TEARDOWN phase are executed together with the PROCESS.
Do you know if it is possible to set the stmcompiler so to execute the SETUP and TEARDOWN of each node just once and so using CPUs resoruces to just run PROCESS phase?

Thanks in advance for clarification.

Dear @antonio.iovine,
Could you share details about the usecase? Are you using node multiple times in application graph? Generally the workflow is setup-> process->teardown.

Yes i apologize for the confusion. it is indeed working like that according to the logfile:

Dear @antonio.iovine,

So. You don’t see any issue and topic can be closed?

6

it’s a feature, not a bug.

7

Yes, by mistake i had called the node multiple time, as you suggested to check, and now SETUP passes are executed just once per node at the beginning as expected, as well TEARDOWN ones at the end of the execution.

Topic can be closed.

Thanks for the hint.
