PALO ALTO, CA -- Hewlett-Packard Company (NYSE:HWP) today announced that it holds the number one market position for Itanium(tm)-based workstation shipments worldwide for the third quarter of calendar year 2001. This was the first full quarter in which these systems shipped. According to reports by industry research and advisory firms Gartner/Dataquest and International Data Corporation, HP is the leading Itanium-based workstation vendor -- number one in Itanium-based workstation revenues and shipments. Both the Gartner and IDC reports show that HP shipped more than one and a half times its closest competitor and holds 50 percent of the Itanium-based workstation market. "The level of enthusiasm for the Itanium architecture HP co-developed with Intel is steadily increasing," said Barry Crume, business product manager for Itanium workstations, HP Technical Computing Division. "HP's workstation market share growth during the third quarter also reflects the advantage of being the only Itanium-based supplier shipping a commercial UNIX." HP's Itanium-based workstations support three 64-bit operating systems: HP-UX 11i version 1.5, Microsoft® Windows® XP 64-bit edition and Red Hat Linux 7. The workstation's large memory addressing capability, large number of registers and advanced compiler technologies work together to make this the architecture of choice for power users. The single processor model is a cost-effective solution application for porting and development. Software ported to this generation will have full binary compatibility with future Itanium-based systems. The dual processor, high-performance model is designed for the toughest problems in Computer Aided Engineering (CAE), Mechanical Computer Aided Design (MCAD) and Digital Content Creations (DCC). Side Effects Software, a world leader in the development of advanced 3D graphics and special effects software for use in film, broadcast and game development, is one of several DCC software developers porting applications to the Itanium platform. In addition, Sony Picture Imageworks, in an effort to improve productivity, is currently testing HP's Itanium-based workstations for processing-intensive tasks such as rendering and compositing
