Abstract
Provided are a method, information processing system, and computer readable medium for identifying active bits in a vector. The method comprises receiving a pointer associated with a vector of bits. The pointer is associated with a current bit within the vector of bits. The vector of bits if grouped into groups of a mathematical power of two, which is any non-negative integer powers of two. One or more current groups are determined which are the groups of the mathematical power of two comprising the current bit. The one or more current groups of the power of two are analyzed. A largest group of the power of two is identified in the one or more current groups comprising all empty bits. The pointer is set to point to a bit following a last bit in the identified largest group of the power of two comprising all empty bits.
