const tSize mds::base::PartedData::BLOCK_SIZE = 1 << DIV_SHIFT

Data block size in elements.

• The block size must be a power of two!

const tSize mds::base::PartedData::DIV_SHIFT = 24

Divisor used to calculate an index j of a concrete data block for a specified data element i: j = i / BLOCK_SIZE = i >> DIV_SHIFT.

const tSize mds::base::PartedData::MOD_MASK = BLOCK_SIZE - 1

Mask used to calculate an index k of a subscripted element i within a data block: k = i % BLOCK_SIZE = i & MOD_MASK.
