Detailed Description

Key (keyType) related functions and kernels.

Function Documentation

key2Char()

CUDA_CALLABLE_MEMBER void KeyNS::key2Char	(	keyType	key,
		integer	maxLevel,
		char *	keyAsChar
	)

Convert a key to a char for printing.

Parameters

[in]	key	Key to be converted
[in]	maxLevel	maximum (tree) level
[out]	keyAsChar	key as char

Definition at line 5 of file subdomain.cu.

key2proc()

CUDA_CALLABLE_MEMBER integer KeyNS::key2proc	(	keyType	key,
		SubDomainKeyTree *	subDomainKeyTree
	)

Convert the key to the corresponding process.

The mapping from a key to a MPI process via ranges can be implemented by checking in between which successive entries of the range the key is located.

Parameters

key	Key to be evaluated
subDomainKeyTree	SubDomainKeyTree class instance

Returns

Process key belongs to

lebesgue2hilbert() [1/2]

CUDA_CALLABLE_MEMBER keyType KeyNS::lebesgue2hilbert	(	keyType	lebesgue,
		int	maxLevel,
		int	level
	)

lebesgue2hilbert() [2/2]

CUDA_CALLABLE_MEMBER keyType KeyNS::lebesgue2hilbert	(	keyType	lebesgue,
		integer	maxLevel
	)

Convert a Lebesgue key to a Hilbert key.

Parameters

lebesgue	Lebesgue key
maxLevel	Maximum tree level

Returns

Hilbert key
