Hi Joachim/others,
Been through this as well the last few days, but that was with GROMACS
5.1 (this version was specific requested by the user, but assume this
will work for the newer versions the same way).
This is what I did.
1)I updated the easyconfig file by adding the following lines:
versionsuffix='dp'
configopts='-DGMX_DOUBLE=on'
And removed the dependencies on NVML and CUDA, since DP and GPU
support are not good friends:
dependencies = [
('Boost', '1.59.0'),
]
2)Updated the easyblock sanity_check_setp for GROMACS:
def sanity_check_step(self):
"""Custom sanity check for GROMACS."""
suff = ''
if self.toolchain.options.get('usempi', None):
suff = '_mpi'
# Add the _d suffix to the suffix, in case of the double precision
if '-DGMX_DOUBLE=on' in self.cfg['configopts']:
suff = suff+'_d'
/#Rest of the easyblock/
This will work indeed, and we'd love to see a pull request for this so
we can get it included 'upstream'. :-)
There's (again) another way though, solely by touching the easyconfig
file (as a workaround for the easyblock not being aware of -DGMX_DOUBLE
and the _d suffix.
You can specify a custom value for sanity_check_paths, for example:
sanity_check_paths = {
'files': ['bin/gmx_mpi_d', 'lib/libgromacs_mpi_d.a'],
'dirs: [],
}
Of course, you can extend this further.
Please don't try and side-step the sanity check with providing dummy or
too simple paths; it's there for a very good reason, and specifying
actual paths that should be there after the installation may save you
quite a bit of time in the end...
regards,
Kenneth

However, you should be able to do this straight from the
easyconfig, without any required modifications to the easyblock
for GROMACS:
configopts = "-DGMX_DOUBLE=ON"
Be careful you don't hard overwrite possible other 'configopts'
specifications that may be already there…
Hi
Feedback on this, it now fails the sanity check. Sanity checking
seems to be looking for an exe named “gmx_mpi” in this case but, as I
outlined this is now called “gmx_mpi_d”. It is also looking for a
library "libgromacs_mpi.a” but that is now “libgromacs_mpi_d.a”. I
checked the d-versions have been build but since it fails the sanity
check, I don not get a module :(
Based on that a “double” feature needs to be developed deeper into the
framework, I see no way how to modify the setup for the modified
filename :(
Best wishes
Joachim
