Exactly the same output from different simulations

[Haolong]

Hello Dr. Dubbeldam,

I got exactly the same output from different simulations, which have the same input files.

This happens around 2 out of 10 works with same input files.

Does it mean these 2 works are using the same array of random numbers?

Kind regards
Haolong

The randomseed is taken from the system time. if you submit lots of jobs to a cluster which start at the same time, they might use the same random seed.
The random-seed can also be set by hand in the input file.
