Killed after OK compilation using 3D arrays

[luiceur]

My problem is that i am trying to use a very big 3d array: a(10000,10000,10000).
When i compile it,it's working without any errors,but when i try to run it,the response is just Killed.
I thougth that could be my memory,but i thing i have enougth memory to run it:cat /proc/meminfo

Does anyone know how can i make sure if is not a memory problem?
Here is the code:

PROGRAM Main
IMPLICIT NONE

integer:: i_viv
integer actual(10000,10000,10000)
do i_viv = 1,10000
if(i_viv.eq.1000) then
actual(i_viv,i_viv,i_viv)=i_viv+2
endif
enddo
end

If i change integer actual(10000,10000,24) it works. How could i know which is the reason for the killed response??
Thanks everybody

With default integer index, you will be able to address only within an 8GB array. On any ifort platform other than ia64, the usual way to use arrays bigger than 2GB is to declare them ALLOCATABLE.

Thanks a lot,i think it works.
At this moment it is running,so probably you are rigth.
ALLOCATABLE is the solution.
