Dear Mark,
Thank you for the answer. I was afraid that this is the only possibility to
fix it.

Hi,
Rolling distros tend to have only one version of things available, leading
to symptoms as you describe, for which the remedy is to recompile.

Dear Gromacs Users,
After my system update (Manjaro), I can not run Gromacs anymore. I noticed

Thanks for your words. Yes, we have going on research and we look to the

We did some work on electric field code but we could not call the velocity

Sure, makes sense. Note that strictly speaking this is not an "overclock",
but a manual "boost clock" (to use terminology CPU vendors use). Consumer
GPUs automatically scale their clock

Typically, deuterium is treated with the same parameters as H, but with double
the mass. Most papers don't even bother with the re-parameterization, using the
argument that the bond-lengths will not change substantially. Instead the
authors focus on how the dynamics are slowed.
If you really

There are tons of published studies that have done MD with deuterium. I
suggest you start there.

No, because appending is the default behavior. Specifying -append just
invokes what mdrun does on its own. If you want a separate file, add

Increasing the mass will also change the vibrational frequency of any
bonds involved, requiring a reparametrization of the bonded force
constant. If you're
A quick update. FFTW is supposed to create fat binaries and ignore the AVX
that it cannot use. Regardless, this did not happen the right way. I've
modified the src/contrib/fftw/CMakeFiles/fftwBuild.dir/build.make and
removed the --enable- "512avx" and other terms and this removed the issue.
Dear Gromacsers,
After compiling gromacs successfully with SSE4.1 it suggested AVX_256
instead. With AVX_256 the compilation is interrupted with the FFTW error
below. In this case I am in need of more CPU power due to the multiple GPUs
installed.
I would at least first try to hardcode a test Lorentz force for e.g. a
given constant magnetic field to see what happens and whether you can
observe anything fun.
On an unrelated note, I just want to say that it is great to see that
there is scientific research going on in Iraq after years of
I thought you are a developer ;)
I think updating electric field file is not a problem but the
complicated thing is what are the other files that related to it. Such as
how to implement it in mdp files which I think need to update different
files. If there are any analyzing commands need updating,
I suggest to check this one:

simulations of S-nitrosated thioredoxin. Biochem Biophys Res Commun. 2008 Dec
