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.

DearGromacs users
I have encountered something strange. I have installed Red
Hat Enterprise Linux 6.1 6.2 on two machines recently and then lam 7.1.4,
fftw 3.3.2 and Gromacs 4.5.5 .
During linux installation, everything went well I didn`t
face any complain or receiving any error, as well as in lam, fftw and
Gromacs
installation, But when I run an MD job on both of these machines, at first
everything seems normal but after some steps ( usually multi thousands
steps), the
job doesn`t proceed. Log file does not show any change or there is no
error.
Obviously the job is stopped while terminal shows all the processors are
100%
busy.
I have also reinstalled the linux and the mentioned programs
too but it did not solve the problem. I don`t have any idea what the
problem
is. Any comment or suggestion would be highly appreciated.
Thanks in advance,
Niloofar
