ILLIAC IV

Supercomputer

The ILLIAC IV was the first massively parallel computer, originally designed to hold 256 64-bit floating-point units and four central processing units able to process a billion operations per second. Budget constraints limited the completed machine to a single quadrant of 64 floating-point units and one CPU, an array-processor design that its own documentation describes as single instruction, multiple threads.
