Dear experts,
I have successfully installed a normal gromacs 4.5.4 installation on
one of my machines.
I have read the Installation Instructions that "As of GROMACS 4.5,
threading is supported, so for e.g multi-core workstations, MPI is no
longer required."
Does this mean that there is no longer the need to do a second
configuration with --enable-mpi?
No, it means that --enable-mpi is not necessary for use of GROMACS in
parallel on multi-core workstations. Thus, many situations will require it.
Upon trying to configure using this command:
./configure --enable-mpi --program-suffix=_mpi
There is an error as below:
checking size of off_t... configure: error: in `/root/gromacs-4.5.4':
configure: error: cannot compute sizeof (off_t)
See `config.log' for more details.
That error is found repeatedly in the archives. Your MPI compiler is not
available and/or configured correctly. See the details in config.log.
