By Charles Petzold

What do flashlights, the British invasion, black cats, and seesaws need to do with pcs? In CODE, they convey us the creative methods we manage language and invent new technique of speaking with one another. and during CODE, we see how this ingenuity and our very human compulsion to speak have pushed the technological thoughts of the prior centuries.

Using daily items and well-known language structures reminiscent of Braille and Morse code, writer Charles Petzold weaves an illuminating narrative for someone who’s ever puzzled in regards to the mystery internal lifetime of desktops and different clever machines.

It’s a cleverly illustrated and eminently understandable story—and alongside the way in which, you’ll realize you’ve received a true context for figuring out today’s international of desktops, electronic media, and the web. it doesn't matter what your point of technical savvy, CODE will attraction you—and even perhaps wake up the technophile within.

ESOP 2012, LNCS 7211, pp. 26–46, 2012. c Springer-Verlag Berlin Heidelberg 2012 What’s Decidable about Weak Memory Models? 27 that check whether programs are exposed to specific relaxations [7,9,20], fence insertion tools [14,15,17], verified compilation [10,24,23], and formal models that closely approximate commercial multiprocessors [21,22,25]. Nevertheless, many foundational questions about weak memory models remain. For instance, given a finite-state concurrent program under weak memory model, what is the complexity of deciding if a particular erroneous state can be reached?

To establish that the state reachability problem for NSW is decidable, we proceed in two steps. First, we define an operational model for NSW where reads do not need to be stored, but still allowing the precise simulation of all their possible reorderings due to the read-to-read relaxation (section 5). The key idea for tackling this issue consists, roughly speaking, in using a buffer storing the history of all the past memory states, in addition to informations about the most recent value read by each process on each variable.

For instance, we show that adding the read-to-write relaxation to TSO (total store order) results in an undecidable memory model. In such a relaxation, a processor eagerly makes a write visible to other processors before a prior read has completed. Such speculative writes can result in causal cycles, a well known memory model hazard [12,19]. On the other hand, a memory model that avoids this relaxation but otherwise remains general by allowing read-to-read, write-to-read, and write-to-write relaxations together with read-read and write-write fences is actually decidable.
