Matrix size overflow

[Pablo_Guerron]

Hi,

My project includes a large matrix (30000x200x20). During compilation I get the error

fatal error LNK 1248: image size exceeds maximum allowable size (80000000)

If the matrix size is 20000x200x20, no problem at all.The system is Windows 7 with intel fortran 11.038 (64 bit). Any suggestion?

Pablo

Do you need to increase the stack size? This is a compilar option.

I had to do this for my project, which has many large arrays.

Thanks, can you tell me how to increase the stack size?

The solution is not to increase the stack size, but use ALLOCATE to declare the array, eg

real*8, allocatable, dimension(:,:,:) :: matrix ! declaration statement

ALLOCATE ( matrix(30000,200,20) ) ! allocate statement

If I interpret the TYPE of the matrix you are declaring, it is not too large, but this isthe best way to declare large arrays.
