Notes:

The following hardware was used for measurements:
- 45nm Intel(R) Core(TM)2 Duo processor – 2 Quad Core CPUs (256Kb L1 and 12288Kb L2 cache), 2.8GHz, 8GB of RAM
- Intel(R) Core(TM) i7 processor – 1 Quad Core CPU (256Kb L1, 1Mb L2 cache and 8Mb L3 cache), 3.2GHz, 4GB of RAM
- Intel(R) Itanium(R) 2 processor – 4 Dual Core CPUs (64Kb L1, 2560Kb L2, 24Mb L3 cache), 1.6GHz, 8GB of RAM.
Performance is measured over the vector length of 1000 elements.
