Lincoln Greenhill (Harvard/Smithsonian) and MWA Collaboration The Murchison Wide-field Array (MWA) is a low-frequency, large-N, radio interferometer whose key science goals include detection of the power spectrum of neutral Hydrogen brightness fluctuations, at multiple redshifts, arising from cosmological reionization. I will present a status report on the project including highlughts from recent observations with the 5% testbed deployed in the Australian Outback. The MWA is a pathfinder for the Square Kilometer Array (SKA). I will discuss a possible evolution that begins with present-day instruments such as the MWA. I will comment in particular on computing, which will be one of the great challenges. The MWA features a novel application of massively parallel (GPU) technology, which holds lessons in enabling SKA early universe science.
