Title: Clayton D Andreasen: Innovator in Parallel Task Distribution

Introduction

Clayton D Andreasen is a notable inventor based in Rosemont, MN (US). He has made significant contributions to the field of computing, particularly in the efficient distribution of parallel tasks. His innovative approach has led to the development of protocols that enhance communication between user applications and operating systems.

Latest Patents

Andreasen holds a patent for "Methods for efficient distribution of parallel tasks to slave processes." This patent describes three new, efficient protocols for providing communications between a user's application program, a Multiprocessing Library, and the host Operating System. The protocols, termed WAKEUP, GIVEUP, and CONTEXT-TO-USER-SPACE, utilize a conduit for communication that minimizes the need for expensive system calls. A primary application of these protocols is in scheduling multiple Central Processing Units (CPUs) within a single user program in a multi-CPU, multiprogramming, multi-tasking environment. WAKEUP enables a master process to request the asynchronous scheduling of slave processes for parallel task execution. GIVEUP allows a slave process to complete its task before being interrupted by the Operating System. CONTEXT-TO-USER-SPACE provides other slave processes the chance to execute interrupted tasks that were not completed under GIVEUP.
