Dear Amber Community,
I am running a minimization of a polymer on two different systems, same
input parameters.
The one system is running on an octane with 2 processors, the other run
is run on a cluster where it uses 4 processors.
The run on octane starts to show "Restarted due to Linmin failure" after
some time, while the cluster does not. Why does this happen, and what
does it mean?
I will include the output right before this error from both files:
