Dear Gromacs users,

I was running the saltbridge calculations for a dimeric
protein simulation using g_saltbr, But its taking very
long time, almost four days still its not completed.
Could anyone has suggestion regarding this issue? I am
using the same system -
Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
where i ran MD. Please give some suggestion as to how to
increase the speed of calculation.
Command i issued was:
g_saltbr -f ../traj.xtc -s md.tpr -t 0.4 -sep


g_saltbr calculates properties of all possible ionic pairs in the system, so if there are many, the calculation might take a long time. Four days sounds ridiculous, and perhaps the program has frozen by exhausting the available memory.
