GPU library not compiled

Based on my searches, I want to be sure that lammps-11Aug17 is compatible
with sm_20. Any idea?

Or lammps config files has dropped that sm version?

​LAMMPS doesn't care. what matters is your CUDA version and driver.
watch your screen output and kernel message buffer.
also, make sure that you delete all objects after you change makefiles and
recompile from scratch.


Normally, I do

cd src

make clean-all

cd …/lib/gpu

make -f Makefile.linux clean

vim Makefile.linux

make -f Makefile.linux

cd …/…/src

make yes-gpu

make mpi

Is that OK?

Cuda 8 is the last version that supports sm_20.
