Thanks for the explanation Josh. I intended to do only 2 micro second simulation and my system is small enough for 100 ns per day simulation.

Run 10 simulations that are only a billion steps each. You are running into the limitations of 32 bit integers, which can't represent numbers larger than 2^32 (around 2 billion). Just as a warning, at around a ms per step, this will take you 115 days.

I am trying to do a really long simulation on NAMD but its showing following error.
how can I fix this problem?
