Dear Francois,
Actually I used the Amber12 resp.F with modified limits in limits.h with -mcmodel=large, before Jean suggested me to use your resp version, and it worked. So is there any specific reason that you suggest me to use it instead of the original version?
It seems that the values used in Amber12 resp.F are commented out; although I don't know fortran! However, it worked.
No I am not sure about the amount of RAM it can get in my machine and I don't have chance to check it with "top" as it is killed immediately.
Maxq=20000 is enough for my case, but I am curious about the upper limits because I am thinking about having bigger systems in near future...
