HI,
The machine I used have 6GB physical memory. However, when I run the c++ program I found the biggest array I can assign like
double A[10000][100]
I complied as:
$ gcc test1.cpp -o test1 $ ./test1'
When I increased the array size to double A[10000][120], it gave the message:
'Segmentation fault'
Is there any way to solve the problem?
Thanks!
here is the detail information of my machine:
1) cat /proc/meminfo
