OK, I do basically the same, but instead of starting the second
equilibration from the same structure for each lambda, I start from the
final structure of the previous lambda (still, I equilibrate before
production for each lambda). I don't see why this strategy should be
worse the one you outlined, unless there was something strange/bad
happening at some lambda value, which is already bad on itself.
Granted, there is the obvious advantage of parallel runs, but when you
only have one computer this is unimportant (and maybe with the
"sequential" run you can go with shorter equilibrations).
Am I missing anything? When you talk about "sequential" run, do you
mean no equilibration for each lambda? (there I do see a problem).
