Detailed Description

Polymorphic memory resource allocating huge pages with specified NUMA policy.

Memory is page-aligned and allocated size is rounded up to nearest full page.

Allocations are performed using numapp::AllocateHuge() and deallocations use numapp::FreeHuge(), see numapp_alloc_huge for details.

Attention: This is not a suitable general purpose memory resource as it is generally slow and always allocates full pages and should be considered to be a block allocator serving a higher level allocator that is aware of this, with blocks of memory.
