Dear all,
I'm using Amber16 with AmberTools16 and CUDA-8.0.
I made a fresh install for Amber16 pmemd.cuda using
./configure -cuda gnu && source amber.sh && make install
After that, pmemd.cuda was installed and it worked. However it did not
install the AmberTools (cpptraj, tleap, etc). So I then ran
./configure gnu && source amber.sh && make install
to get those tools.
However now, whenever I run pmemd.cuda as before, I get an error:
> $AMBERHOME/bin/pmemd.cuda -O -i 01_Min.in -o 01_Min.out -p prmtop -c
inpcrd -r 01_Min.rst -inf 01_Min.mdinfo
cudaMemcpyToSymbol: SetSim copy to cSim failed invalid device symbol
And now I can not get rid of this error.
I've tried fresh installing, reinstalling pmemd.cuda from scratch, without
the tools, and it didn't work this time. I've tried installing the
AmberTools first and then Amber16 with cuda second, but now still gives the
same error.
I am very confused, and I can't think of why it would work before and now
no longer works.
Has anyone else received this type of error, or could give some advice onto
how to proceed? I've seen in the forums that this error had been received,
but it was because of out-of-date drivers which should not be the case here.
Thanks!
By the way, here is the output of my minimization (which worked previously)
> cat 01_Min.out
