template<typename T>

Galois::LargeArray< T >::LargeArray	(	void *	d,

template<typename T>

void Galois::LargeArray< T >::allocateInterleaved

(

size_type

n

)

[inline]

Allocates interleaved across NUMA (memory) nodes. Must.

template<typename T>

void Galois::LargeArray< T >::allocateLocal	(	size_type	n,
		bool	prefault = true
	)			[inline]

Allocates using default memory policy (usually first-touch).

Parameters:

	n	number of elements to allocate
	prefault	Prefault/touch memory to place it local to the currently executing thread. By default, true because concurrent page-faulting can be a scalability bottleneck.
