COMPUTER programmingToday, virtually all operating systems support multithreaded programming. In fact, threads are easier to use and more efficient than processes. This paper presents a possible way of using mu
Similar to multithreaded programming, the basic idea of multidevice programming is to setup the device once when the creating the process. After initialization, you can use the device throughout the program. An example of using MPI to create the host processes is shown in Fig. 4. Sign in to...
The are two types of processors that we can encounter while doing parallel programming: physical processors and logical processors. The number of logical processors (processors that the operating system and applications can work with) is (usually) greater or equal to the number of physical processors...
As in previous Solaris system releases, a module must not call another module'sputorserviceprocedures directly. The DDI/DKI routinesputnext(9F),put(9F), and others in Section 9F must be used to pass a message to another queue. Calling another module's routines directly circumvents the design...
Oracle Developer Studio includes the Thread Analyzer tool. This tool lets you analyze the execution of a multithreaded program. It can detect multithreaded programming errors such as data races or deadlocks in code written using the using the POSIX thread API, the Oracle Solaris thread API, OpenMP...
These slow down a single-threaded application, waste system resources, and produce misleading results when you debug your code.Figure 7-1 summarizes the compile options. Figure 7-1 Compilation FlowchartIn mixed usage, you need to include both thread.h and pthread.h....
Reasoning about multithreaded programming is already hard enough. Even when using the locking protocol, you need to worry about how updates from multiple threads will interleave, but at least when using locks the granularity can be as fine or as coarse as you need. Without locks, t...
CSP.NET is a Microsoft.NET 2.0 library designed to ease distributed and concurrent programming in any language supported by the .NET platform—C#, VB, and C++. CSP.NET is a new library, but it’s built upon an old paradigm named Communicating Sequential Processes (CSP) first introduced in ...
Note For a similar discussion from the MFC point of view, see Multithreading: Programming Tips and Multithreading: When to Use the Synchronization Classes.Each thread has its own stack and its own copy of the CPU registers. Other resources, such as files, static data, and heap memory, are ...
Exception handling in 16 bit OS/2 is managed on a per process basis and this has created problems which the present invention improves upon and overcomes. Each thread registers an exception handler by using an application programming interface (API) call and this causes an entry to be made in...
