much less than 2G memory is used, but still occur the Fatal error LNK1248: image size exceeds...

Hello,

I use Intel Visual Fortran 2011 with VS 2010, in a 32 bit system. The memory is 4G, of which 3.4G is available.

I've learnt from the folloing topic that  Windows limits static code and data to 2GB.

I used several large 3-D arrays by declaring them with fixed bounds in a module. But all these 3-D arrays occupies only  about 1 G. Ohther  variables, no matter declared in the module or as local varibles, are small when compared with the arrays above. Unfortunately, there still occurs the Fatal error LNK1248: image size () exceeds maximum allowable size (80000000).

I cann't understand this. Could you please help me out?

Thank you big time in advance.

Following is a part of the module and the error:

there are 7 zr arrays with = 1000 x 2 *6 *10000 element of 8 bytes which is  6,720,000,000  bytes hence the error.

Thank you app4619. What a boring mistake I've made.

Could I ask you one more question? Can I make use of more than 2G memory by using  ALLOCATE?  If so,I will not have to change my system because I have memory of 3.4G.

Not with a 32-bit application. The amount of physical memory you have is not directly relevant. If you have a 64-bit system and build a 64-bit application, then ALLOCATE will let you exceed 2GB.

Thank you for your detailed explaination Steve.
