Due to incorrect information provided by IBM, the eighth paragraph of the story “IBM updates high-end servers, returns to water-cooling,” which posted to the wire Tuesday, misidentified the IBM research lab that developed its new Hydro-Cluster water-cooling technology. It was IBM's research lab in Poughkeepsie, New York.

The eighth paragraph has been corrected and now reads:

The Power 575 supercomputer uses a new Hydro-Cluster design developed at IBM's research lab in Poughkeepsie, New York. It uses a network of copper pipes that sit just above the processors and carry cold water to them and warm water away.
