was appointed CEO. Ungaro had joined Cray in August 2003 as Vice President of Sales and Marketing and had been made Cray's President in March 2005. On November 13, 2006, Cray announced a new system, the Cray XMT, based on the MTA series of machines. This system combined multi-threaded processors, as used on the original Tera systems, and the SeaStar2 interconnect used by the XT4. By reusing ASICs, boards, cabinets, and system software used by the comparatively higher volume XT4 product, the cost of making the very specialized MTA system could be reduced. A second generation of the XMT is scheduled for release in 2011, with the first system ordered by the Swiss National Supercomputing Center (CSCS). In 2006, Cray announced a vision of products dubbed ''Adaptive Supercomputing''. The first generation of such systems, dubbed the ''Rainier Project'', used a common interconnect network (SeaStar2), programming environment, cabinet design, and I/O subsystem. These systems included the existing XT4 and the XMT. The second generation, launched as the XT5h, allowed a system to combine compute elements of various types into a common system, sharing infrastructure. The XT5h combined Opteron, vector, multithreaded, and

compute processors in a single system. In April 2008, Cray and

announced they would collaborate on future supercomputer systems. This partnership produced the Cray CX1 system, launched in September the same year. This was a deskside
