[Nek5000-users] Sharing parameters between processors

[nek5000-users at lists.mcs.anl.gov]

Hi Paul,

Thanks for your quick answer! These are random numbers I use. They is not a
very large number of them, I have about 100 elements in my array. However,I
need to use the same on all my domain, but as they are random, I can only
generate them once.

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?

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
