Problem with stack overflow

[armeros]

Hi everyone,

I have an error message forrtl: severe(170): Program exception - stack overflow

My program is doing some grid search. It ran fine with a small number of grids, but then I got this message when I increase the number of grids to the realistic level. I read the topic

https://software.intel.com/en-us/forums/topic/299402

but I still don't understand. ( I use Intel Visual Fortran Compiler with IMSL libraries (use include 'link_fnl_static_hpc.h') and I ran the program by clicking Start without debugging so I don't know what "ifort" is.

Anyone could suggest me the way out of this ?

Thank you very much.

PS. I use Windows 7 with Intel(R) Xeon(R) CPU W350 @2.80GHZ
RAM 6.00 GB
64 bit operating system (but the compiler was installed as 32 bit due to some installation problem)

ifort is the fortran compiler.

From visual studio, under debug/exceptions, check win32 exceptions.
Press F5 to run your program.

So, how would I solve this overflow problem ? Thanks.

When the program stops in the debugger, it tells you where the problem lies. If you're saying that it works with small amounts of data but not with large ones, then it is a matter of increasing your array sizes.

If it is badly written, say something like

real res(5), oneway(5,2), otherway(2,5), ranks(2), flat(10)
do ii = 1, 5
   ...
   do jj = 1, 2
      ...
   end do
end do

Then you may have problems. If it is written properly

integer, parameter:: XMAX=5, YMAX=2
real res(XMAX), oneway(XMAX,YMAX), otherway(YMAX,XMAX), ranks(YMAX), flat(XMAX*YMAX)
do ii = 1, XMAX
   do jj = 1, YMAX

Then it will be really easy to modify
