stormm::structure::CacheResource Class Reference

An object to hold temporary data for a particular work unit (whether bonded or non-bonded), resident in GMEM but private to a particular thread block. This object must be allocated in such a way as to be ready to hold the private workspaces of any thread blocks that will make use of it. The object is arranged to support operations based on PhaseSpaceSynthesis respresentations of systems' coordinates and forces. More...

Detailed Description

An object to hold temporary data for a particular work unit (whether bonded or non-bonded), resident in GMEM but private to a particular thread block. This object must be allocated in such a way as to be ready to hold the private workspaces of any thread blocks that will make use of it. The object is arranged to support operations based on PhaseSpaceSynthesis respresentations of systems' coordinates and forces.

Constructor & Destructor Documentation

CacheResource() [1/2]

stormm::energy::CacheResource::CacheResource	(	int	block_limit_in,
		int	atom_limit_in )

The constructor does not take a GPU description, but instead maximum numbers of blocks and atoms per block that might be required, allocating space as appropriate.

Overloaded:

• Provide a general work unit size to allocate
• Provide a pair of work unit sizes to allocate (the larger of the two will be taken)

Parameters

block_limit_in	The maximum number of thread blocks that will need resources
atom_limit_in	The maximum number of atoms per block requiring local copies
atom_limits_in	Maximum numbers of atoms per block requiring local copies, for work units containing organic molecules in the "x" member of the tuple and work units assumed to contain only water in the "y" member
