Abstract

With today's new computers the trend is for CPU speeds to increase at a faster rate than I/O speeds. I/O time is therefore becoming a more significant fraction of each job's time, and the I/O subsystem is being driven nearer to its capacity. This makes it harder for system programmers to tune systems, and I/O bottlenecks are more likely to occur. In addition, today's increasingly powerful computers are permitting more complex workloads with the consequence that system programmers need simpler ways to control the computing systems. Accessing I/O devices to search for and fetch program modules from online system program libraries is a pervasive cause of I/O delays in large systems.
