It deals with a large model. first, I use "f77 aa.f -o aa.exe" to compile it; second, I use "size aa.exe" to view the size of the exe file; third, I use "./aa.exe" to run the program. --- Problem --- When the size is larger than 1.0 G, I got the message "Segmentation fault (core dumped)" when I run "./aa.exe"; Then I adjusted the model size, and redo step1,2,3. This time the program runs well. --- Question --- My computer has 1.5G memory; does anyone know how to fix this problem so that I can run the program with a larger model (my research requires me to run a large model)? such a s modify the configuration or settings of the Linux system... ( red hat linux 8.0 )? ( I've thought about MPI; But it's not easy to modify the program for parralel computing, so I want to find another solution) Thanks a lot!!
