Practical Concerns in Multitasking on the Cray X-MP
Multitasking and vectorization are both optimizations which exploit program and machine parallelism. Many of the goals for obtaining increased performance through multitasking are identical to those for vectorization, only the terminology and underlying structures are changed. High performance on the CRAY X-MP is achieved by addressing familiar concerns in a new setting. Practical objectives in programming as well as limitations in performance are described for a multitasking environment.
