Hello,

I have two C programs. In my first C program I am assigning 2GB memory space to 
an integer array and in my second C program I am assigning 4GB memory space to 
another integer array. I am assigning memory space via C's malloc() function. 
Both my first and second programs work fine on my Linux laptop (with 16GB 
memory).

I have executed both first and second programs inside Gem5 in Full System (FS) 
mode. I observed that the first program was executed properly in Gem5. However, 
for the second program, I am getting the "Out of storage: Cannot allocate 
memory" message from the Gem5. Do you know why I am getting the above message? 
How to simulate more than 2GB memory in the Gem5 Full System mode? Please let 
me know.

Thanks a lot.

Sincerely,
S.M.Shamimul Hasan
