Opening the stacks
Opening the stacks
Using multiple processors to perform many operations simultaneously, which is beneficial for real-time tasks but may not be economically advantageous for general use.

The chapter discusses the physical and technological limits on increasing computer speed, emphasizing the constraints imposed by signal travel time and the benefits and limitations of parallel processing. It highlights the rapid growth in computer memory capacity over time and considers the advantages of integrating multiple processors within a single system to optimize resource use and efficiency. The author anticipates continued improvements in memory size and system integration rather than dramatic speed increases.
This chapter surveys three vintage computing systems: the CDC 6600, the Interface Message Processor (IMP), and the Honeywell H316 Kitchen Computer. The CDC 6600, designed by Seymour Cray, was notable for its speed, innovative architecture, and cooling system, primarily used in scientific and nuclear research. The IMP was a pioneering packet router for the ARPANET, enabling reliable computer networking through packet switching, while the Honeywell Kitchen Computer was an early, commercially unsuccessful attempt to bring computing into domestic spaces.
The ILLIAC IV was a Burroughs supercomputer developed over nearly a decade starting in 1975, designed to implement the SIMD model for parallel processing. Despite being the fastest computer for certain parallel tasks, it faced challenges including limited practical applications, high cost, and political opposition due to its military funding, leading to relocation and eventual decommissioning in 1982. Only a fraction of its intended processing elements were built, and the project ultimately failed to fulfill its original promise.
