parallel calcultion problem in serpent 2.23-two burnup zones

Post by Mohamed Salah » Thu Apr 09, 2015 3:43 am

Hi Jaakko,

I successfully installed Serpent 2.1.23
my model has two burn up zones, it run well in a single core for both serpent 1.19 and Serpent 2.23
Now my problems are,

1- My model doesn’t run the burnup calculation in parallel using MPI , but it can run it successfully on a single core. I did all the probable changes in the Makefile like to add or remove the openmp (three lines) in the makefile . the screen output for Serpent 2 is shown down
2- Also the transport calculations of the model is running well on the serpent 1.19 on parallel . But it stop as i add the burn up cards in parallel MPI
3- The transport calculations run well in parallel for serpent 1 and 2

i tried to remove the content of the file rendezvois.c as one of the previous question in the forum but it doesn't work
