Public Member Functions
	MeshKlManager (const GpuDetails &gpu_in=null_gpu)
	As the construction of virtually any mesh will provide enough operations for a GPU to run at acceptable efficiency. The constructor will therefore be based on the GPU specs as if the workload is for a single mesh.
int	getArchBlockMultiplier () const
	Get the architecture-specific block multiplier. This will run a minimum number of blocks per streaming multiprocessor on some cards, specifically NVIDIA's GTX 1080-Ti, when large blocks cannot use more than 32k registers in all.
int2	getMeshKernelDims (PrecisionModel prec, GridDetail picture, BoundaryCondition bounds, MappingActivity process) const
	Get the launch parameters for a mesh computation kernel.

	Get the GPU information for the active GPU.
void	printLaunchParameters (const std::string &k_key=std::string(""), const char *true_class_name=generic_kernel_manager_name) const
	Print out the kernel launch parameters found for this workload.

Member Function Documentation

getMeshKernelDims()

int2 stormm::card::MeshKlManager::getMeshKernelDims	(	PrecisionModel	prec,
		GridDetail	picture,
		BoundaryCondition	bounds,
		MappingActivity	process ) const

Get the launch parameters for a mesh computation kernel.

Overloaded:

• Provide precision model, process, mesh type, and boundary conditions, the minimum descriptors for occlusion meshes
• Provide unit cell and interpolant specifications for nonbonded field meshes

Parameters

prec	The precision model in which to perform calculations and present results
picture	The type of potential or field presented by the mesh
bounds	Boundary conditions for the mesh mapper of interest
unit_cell	The unit cell type of each mesh element (and, by extension, of the mesh as a whole)
stencil_kind	The framework for fitting tricubic polynomial coefficients in each mesh element
process	The direction of information flow between the mesh and particles
