This directory has source files to build a library that LAMMPS
links against when using the GPU package.
This library must be built with a C++ compiler, before LAMMPS is
built, so LAMMPS can link against it.
Build the library using one of the provided Makefile.* files or create
your own, specific to your compiler and system. For example:
make -f Makefile.linux
When you are done building this library, two files should
exist in this directory:
libgpu.a the library LAMMPS will link against
Makefile.lammps settings the LAMMPS Makefile will import
The latter file will have settings like this (can be omitted if blank):
Makefile.lammps is created by the make command, by copying one of the
Makefile.lammps.* files. See the EXTRAMAKE setting at the top of the
Makefile.* files.
gpu_SYSINC =
gpu_SYSLIB = -lcudart -lcuda
gpu_SYSPATH = -L/usr/local/cuda/lib64
IMPORTANT: You must examine the final Makefile.lammps to insure it is
correct for your system, else the LAMMPS build will likely fail.
SYSINC is for settings needed to compile LAMMPS source files
SYSLIB is for additional system libraries needed by this package
SYSPATH is the path(s) to where those libraries are
Makefile.lammps has settings for 3 variables:
You must insure these settings are correct for your system, else
the LAMMPS build will likely fail.
user-gpu_SYSINC = leave blank for this package
user-gpu_SYSLIB = CUDA libraries needed by this package
user-gpu_SYSPATH = path(s) to where those libraries are
Because you have the CUDA compilers on your system, you should have
the needed libraries. If the CUDA developement tools were installed
in the standard manner, the settings in the Makefile.lammps.standard
file should work.
