Setting Up and Configuring Project

In the CMakeLists.txt of your simulation project, there are a few configuration options for the MASS CUDA library:

CMake variable	Description	Default value
MASS_NCCL_ROOT_DIR	The root directory of the NCCL library	“” (will try to find in common paths)
MASS_LIBSSH_ROOT_DIR	The root directory of the libssh library	“” (will try to find in common paths)
MASS_MAX_AGENTS	Maximum number of agent instances on each place instance	1
MASS_MAX_NEIGHBORS	Maximum number of neighbors for each place instance	12
MASS_MAX_DIMS	Maximum number of dimensions for the spatial grid	4
MASS_MAX_POTENTIAL_AGENTS	Maximum number of potential agent instances migrating to each place instance	12

To configure these options, set the value of these variables in CMakeLists.txt before adding the MASS library as dependencies.

# Configure MASS CUDA
set(MASS_MAX_AGENTS 3)
set(MASS_MAX_DIMS 2)

# Add MASS CUDA as a dependency
