Abstract: Internet Protocol Version 6 (IPv6) was described in RFC 2460 in 1998 and was designed to succeed Internet Protocol Version 4. In 2005, RFC 4007 was published. RFC 4007 specifies the architectural characteristics and usage of IPv6 addresses with different zones.

Therefore, the legacy applications may accept IPV6 addresses as input, but may not accept zone identifiers. Embodiments include conveying an IPv6 link-local unicast address with an embedded zone identifier to a legacy application.

Abstract: A method, a system and a computer program product for effectively accelerating loop iterators using speculative execution of iterators. An Efficient Loop Iterator (ELI) utility detects initiation of a target program and initiates/spawns a speculative iterator thread at the start of the basic code block ahead of the code block that initiates a nested loop. The ELI utility assigns the iterator thread to a dedicated processor in a multi-processor system. The speculative thread runs/executes ahead of the execution of the nested loop and calculates indices in a corresponding multidimensional array. The iterator thread adds all the precomputed indices to a single queue. As a result, the ELI utility effectively enables a multidimensional loop to be replaced by a single dimensional loop. At the beginning of (or during) each iteration of the iterator, the ELI utility “dequeues” an entry from the queue to use the entry to access the array upon which the ELI utility iterates.
