Executive Summary<br />

Today’s companies are facing significant computing challenges. The demand for network services<br />

continues <strong>to</strong> rise while IT budgets and resources remain limited. For these companies <strong>to</strong> thrive,<br />

something has <strong>to</strong> give.<br />

Leave it <strong>to</strong> Sun <strong>to</strong> innovate. Sun’s UltraSPARC® processor strategy for throughput computing<br />

will usher in a computing revolution by dramatically cutting the cost and complexity of network<br />

computing.<br />

Sun is designing upcoming UltraSPARC processors built specifically <strong>to</strong> maximize application<br />

workload throughput, or the aggregate amount of work done in a given amount of time. These<br />

chip multithreading (CMT) processors are designed <strong>to</strong> execute tens of threads simultaneously—a<br />

sharp contrast <strong>to</strong> the single thread processed at a time by <strong>to</strong>day’s typical processors. As a result,<br />

Sun’s CMT processors will help change the economics of <strong>to</strong>day’s data centers by radically improving<br />

price/performance and lowering <strong>to</strong>tal cost of ownership.<br />

This brief introduces the reader <strong>to</strong> Sun’s throughput computing strategy for UltraSPARC<br />

processors, outline the revolutionary benefits that Sun’s upcoming CMT processors will offer<br />

cus<strong>to</strong>mers, and show how Sun is uniquely positioned <strong>to</strong> successfully bring throughput<br />

computing <strong>to</strong> market.
