The Massively Parallel Processor,to Goddard Space Flight Center and delivered in May, 1983. The MPP is a direct descendant of the ILLIAC IV and shares many of that system’s advantages and disadvantages. The ILLIAC was designed in the mid 1960’s for scientific calculations. The MPP was designed in the mid 1970’s for LANDSAT image pr

The IBM 7030: Stretch,s, magnetic cores) instead of vacuum tubes. Use of semiconductors would permit higher reliability and higher speed. The speed of a floating-point addition was planned to be less than 1 microsecond, and the 8,192 word memory units were to have a speed of 2 microseconds.

The ILLIAC IV,. floating-point operations per second. To achieve this goal, a system with 256 parallel processing elements was planned. Due to technological problems and consequent cost growth, the ILLIAC IV was built with 64 processing elements and attained a speed of 1.6 · 10. floating-point operations per second.

The Massively Parallel Processor, and disadvantages. The ILLIAC was designed in the mid 1960’s for scientific calculations. The MPP was designed in the mid 1970’s for LANDSAT image processing. Each of its 16,384 processors is only one bit wide. It has no built in fixed- or floating-point arithmetic--only a full adder.
