Hi,
Is there anyway we can use ATOMIC blocks which has PROPAGATE statements? I know we cant but if there is some workaround, that can be very much helpful. |

Hi Anthony,
Thanks for the reply. I would like to update a shared variable. The thing is the shared variable values will be updated based on some if-else condition and propagated to different 'OUT' terminals. |

Hi Prasi,
The ATOMIC block is just right for updating the shared variable. After this block, you can then PROPAGATE. If you're trying to hold the value of the shared variable during the duration of the PROPAGATE, then you'd have some very large serialisation issues, as everything else would be help up behind it.
Is there any reason why you cannot update the shared variable in the block, copy the value to a local variable (e.g. the message tree) and PROPAGATE as normal? In this way, you'd get the sharing across instances that you need, and not synchronise downstream.
Does that help at all?
Anthony. |
