Updates the Philox generator state in state skipping sequence sequences ahead. For Philox each sequence is 4 * 2^64 numbers long (equal to the size of a subsequence).

Parameters

sequence	- Number of sequences to skip
state	- Pointer to state to update

◆ skipahead_sequence() [4/4]

FQUALIFIERS void skipahead_sequence	(	unsigned long long	sequence,
		rocrand_state_xorwow *	state
	)

Updates XORWOW state to skip ahead by sequence sequences.

Updates the XORWOW state skipping sequence sequences ahead. For XORWOW each sequence is 2^67 numbers long (equal to the size of a subsequence).

Parameters

sequence	- Number of sequences to skip
state	- Pointer to state to update

◆ skipahead_subsequence() [1/4]

FQUALIFIERS void skipahead_subsequence	(	unsigned long long	subsequence,
		rocrand_state_mrg31k3p *	state
	)

Updates MRG31K3P state to skip ahead by subsequence subsequences.

Updates the MRG31K3P state in state to skip ahead by subsequence subsequences. Each subsequence is 2^72 numbers long.

Parameters

subsequence	- Number of subsequences to skip
state	- Pointer to state to update

◆ skipahead_subsequence() [2/4]

FQUALIFIERS void skipahead_subsequence	(	unsigned long long	subsequence,
		rocrand_state_mrg32k3a *	state
	)

Updates MRG32K3A state to skip ahead by subsequence subsequences.

Updates the MRG32K3A state in state to skip ahead by subsequence subsequences. Each subsequence is 2^76 numbers long.

Parameters

subsequence	- Number of subsequences to skip
state	- Pointer to state to update

◆ skipahead_subsequence() [3/4]

FQUALIFIERS void skipahead_subsequence	(	unsigned long long	subsequence,
		rocrand_state_philox4x32_10 *	state
	)

Updates Philox state to skip ahead by subsequence subsequences.

Updates the Philox generator state in state to skip ahead by subsequence subsequences. Each subsequence is 4 * 2^64 numbers long.

Parameters

subsequence	- Number of subsequences to skip
state	- Pointer to state to update

◆ skipahead_subsequence() [4/4]

FQUALIFIERS void skipahead_subsequence	(	unsigned long long	subsequence,
		rocrand_state_xorwow *	state
	)

Updates XORWOW state to skip ahead by subsequence subsequences.

Updates the XORWOW state to skip ahead by subsequence subsequences. Each subsequence is 2^67 numbers long.

Parameters

subsequence	- Number of subsequences to skip
state	- Pointer to state to update
