I have a fairly stupid question about restart from a checkpoint and binary identical messages, probably because I can't understand the doco.
When I restart (or extend) a double-precision run from a checkpoint involving either dlb or even a different decomposition count (say I changed the number of parallel threads), I get a message that says it restarted but the trajectory is not binary identical. My question is: I assume this trajectory will continue from the last set of double-precision coordinates and velocities in the cpt file? What is the loss in precision/error propagation of the resulting trajectory as compared to if I started the entire run from the begining? (say I am extending my trajectory from 1ns to 10ns). I guess I understand that both trajectories would be "equally valid" but not binary identical, but what does this mean in terms of things like ultimate RMSD measurements and so forth? I don't necessarily care that the two concatenated trajectory files will not cmp to zero. -- =============================================================== Peter C.
