This Ardent Titan is one of the four systems donated by a Stanford University professor.
A Titan can have up to 4 cpu boards in stalled. Each board contains a MIPS R2000 microprocessor for scalar operations, as well as a custom designed vector processor with divide, a pipelined multiplier, and a pipelined adder/subtracter as independent arithmetic function units. Data is streamed from shared memory directly to the vector registers via 1 store and 2 load pipes. The vector registers are 8192 words long and can be configured in any mode between 8192 registers of one word each to 32 registers each of 256 words. Each word is 64-bits long. The clock cycle time is 62.5 nsec, and each vector processor is rated at 16 Mflops, giving a maximum potential of 64 Mflops.
A major feature of the Titan is its integrated graphics support. Up to two graphics boards (base graphics + extended graphics) can be attached to the bus and are powerful processors in their own right. All pixel manipulation is done on the graphics boards minimizing traffic between them and the vector processors, which can be employed on related or independent computation to the graphics processing. Graphics is supported by PHIGS+ and CGI as well as Ardent's own software package called Dore (Dynamic Object Rendering Environment), which handles image representations from wire-frame through flat and smooth-shading to global ray tracing.
The operating system is fully compatible with the standard AT&T System V.3 UNIX operating system and Berkeley 4.3 Unix with enhancements for communications, high I/O bandwidth, and large applications. Asynchronous reads and a fast file transfer of 1000 Kbyte/sec using disk striping are also supported.
My Titan has a single CPU, 2 memory boards (64MB total), extended (2-board) graphics adapter, and the standard I/O card (2x SCSI, keyboard, mouse, audio, ethernet, 4 x serial, parallel). The hardware appears to be functional, but unfortunately, the hard disk it came with did not have the OS installed. I am, however, in contact with someone who may have installation media for me, so I'm keeping my fingers crossed.
