[Nek5000-users] Sharing parameters between processors

Hi Oscar,

Is there a reason why your quantity is modified only on one processor, and not on the others?

How many values are you working with?

Paul

Hi Nekers,

In my current simulation, I am defining an array containing parameters that are shared between several processors. I have tried to do this in the usercheck subroutine, with a COMMON statement. However, the COMMON statement enables saving the parameters between two successive calls of the usercheck by the same processor, but does not enable to share a variable between two processor. In other words, if I modify the variable a on the processor 1, the variable a on the processor 2 will not be modified, which is not what I want. Any idea on how to do that?

Thanks for your help,

Oscar Valdorez
