[gmx-users] Failure in MD run without any error

[Mark Abraham]

Hi,

Hard to know. LAM was discontinued over 4 years ago. You could have a flaky
file system. Unless you're trying to run a jobsover both machines over
network like Infiniband, you don't even want to use an external MPI library
- single-node performance with built-in thread-MPI will give much better
value.
