The classic neurophysiologic definition of consciousness distinguishes between 2 components, namely vigilance (or arousal) and awareness. Vigilance corresponds to the level of wakefulness, whereas awareness refers to the mental content, which in turn is composed of 2 components being conscious perception of the environment or external world (external awareness) and of our inner world and self-a...

We present Continuation Passing C (CPC), a programming language designed for writing concurrent systems. It features very lightweight threads, both cooperatively or preemptively scheduled, which are compiled to highly-efficient event-loop code. Its compilation passes have been proven correct. CPC has been used to write Hekate, a BitTorrent seeder able to sustain thousands of simultaneously conn...

The attached paper by Andrew Birrell, An Introduction to Programming with C# Threads, originally appeared as An Introduction to Programming with Threads, report 35 of the Systems Research Center, Digital Equipment Corp., Jan. 1989; it was based on the Modula-3 language. A somewhat revised version appears as chapter 4 of Systems Programming with Modula-3, Greg Nelson ed., Prentice-Hall, 1991, pp...

Scheduling in the context of parallel systems is often thought of in terms of assigning tasks in a program to processors, so as to minimize the makespan. This formulation assumes that the processors are dedicated to the program in question. But when the parallel system is shared by a number of users, this is not necessarily the case. In the context of multiprogrammed parallel machines, scheduli...
