Minisupercomputers<br />

Minisupercomputers are designed for high-speed mathematical<br />

computation, and most have the architecture to perform vector<br />

mathematics.<br />

Minisupercomputers must perform some scientific applications using 60or<br />

64-bit floating-point arithmetic at a speed at least one-fourth that of<br />

a Cray-l/S.<br />

Mainframes<br />

Pricing typically ranges between $300,000 and $2 million.<br />

- Mainframes have at least a 32-bit CPU and I/O structure with very large<br />

capability.<br />

- They are typically priced at more than $500,000 and are designed for<br />

batch processing or a large number of users.<br />

- Mainframes support a large number of disks and tapes.<br />

Superminicomputers<br />

- Superminicomputers have a CPU-to-memory data path and a CPU bit<br />

width greater than 24 bits (usually 32 bits).<br />

They are priced between $20,000 and $600,000.<br />

Technical workstations<br />

- Technical workstations are complete standalone general-purpose systems<br />

or distributed network-based systems that contain integrated networking<br />

capabilities in the operating system.<br />

- Technical workstations contain graphics controllers integrated on the<br />

system bus.<br />

- They have a resident operating system and local programming capability,<br />

and they are typically priced at less than $75,000.<br />

This category fits directly into the single-user enhanced computer<br />

system market segment.<br />
