Detailed Description

template<typename T, typename mempool = RAJA::basic_mempool::MemPool< RAJA::basic_mempool::generic_allocator>, typename accessor = DefaultAccessor>
class RAJA::detail::SoAPtr< T, mempool, accessor >

Pointer class specialized for Struct of Array data layout allocated via RAJA basic_mempools.

This is useful for creating a vectorizable data layout and getting coalesced memory accesses or avoiding shared memory bank conflicts in cuda.
