Communication and Concurrency Milner R.
Publisher: PH

Communication is not a separate activity—it needs to integrate into the desktop and business applications you use every day. I know how to use threads, and I'm There aren't good tools for sharing data and communication (or if there are they aren't well enough publicized). Java Concurrency / Multithreading This article describes how to do concurrent programming with Java. A rogue admin can change the IP and/or MAC address(es) assigned to its domU and potentially cause an IP address conflict. One such solution is referred to as message passing concurrency - a model in which threads share no state and communicate with each other via asynchronous messaging. There are also a number of system primitives for inter-process communication such as shared memory, sockets, pipes and other forms of middlewares and peer to peer technology. It covers the Synchronization is necessary for mutually exclusive access to blocks of and for reliable communication between threads. Concurrency is evil When using bridging for Xen Networking and your guests machines (domUs in Xen parlance) are fully managed by third parties, some sort of isolation is specially needed. For a long time when people criticize threads, my feeling has been that (a) they have a point, but (b) threads aren't as hard as they imply because (c) concurrency is always hard, but mostly (d) thread critics need to provide better tools for concurrency. Xen provides an script Looking some help for “Couldn't update kernel counters” or “communication.c:388:–BUG–:” didn't help at all. I've chosen Objective-C for the second part of Joe's challenge, hopefully leveraging Grand Central Dispatch for concurrency. Mike Ash's Friday Q&A's on GCD should be of great use. Communicate only through well-defined immutable messages, do not share any data, and do not use synchronization mechanisms for signaling or data integrity.
