NSNotification and Multithreading
 

I'm trying to get the notification NSTaskDidTerminateNotification in my multithreaded app but I can't get it working. It does seem to work when I tested it on a single threaded app. In init I have [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(taskDidEnd:) name: NSTaskDidTerminateNotification object: myTask]; and I'm quite sure that it gets called because other objects (like myTask) are being initiated there. And the taskDidEnd: method is defined as

- (void)taskDidEnd: (NSNotification *)aNotification
{
     NSLog(@"Task succeeded.");
}

And in dealloc the observer gets removed.

This all happens in an object which is initiated inside a separate thread and I would like to receive that notification inside the same object.

There are 1 answer(s) to this question.


Did you run the run loop on that thread? If not, NSTask won't notice that the task ended (or the task won't have ended yet) and won't post the notification.

The official Sun Java tutorial on concurrency is probably a good place to start. Good luck! Sun has a decent tutorial. But in all honestly, multithreaded programming is exremely difficult. There is a well regarded book, Java Concurrency in Practice. If you really want to learn how to take advantage of multiple cores, look into clojure or scala.

Multithreading in Bash
Multithreading in Bash I would to introduce multithreading feature in my shell script. I have a script which calls the function read_cfg() with different arguments. Each of these function calls are independent. Would it be possible to instantiate these function calls (not scripts) parallelly. Please let me how can we achieve that.. ? Sure, just add & after the command: read_cfg cfgA & read_cfg cfgB & read_cfg cfgC & wait all those jobs will then run in the background simultaneously. The optional wait command will then wait for all the jobs to finish. Each command will run in a separate process, so it's technically not "multithreading", but I believe it solves your problem. Bash job control involves multiple processes, not multiple threads. You can execute a command in background with the & suffix. You can wait for completion of a background command

Java - Multithreading ! What does phrase "synchronization with main memory" mean? http://www.javamex.com/tutorials/synchronization_concurrency_synchronized2.shtml When you have multiple threads each thread may keep a local copy of a variable's value. However the "official copy" of the value is kept in main memory. So what that phrase means is that any local copy of a variable's value will be made consistent with main memory (either reading to check for updates, or writing to publish updates made to the local copy

Multithreading in PHP I recently read about http://php.net/pcntl and was woundering how good that functions works and if it would be smart to use multithreading in PHP since it isn't a core function of PHP. I would want to trigger events that don't require feedback through it like fireing a cronjob execution manually. All of it is supposed to run in a web app written with Zend Framework The pcntl package works quite fine - it just uses the according unix functions. The only shortage is that you can't use them if php is invoked from a web server context. i.e. you can use it in shell scripts... the socket is closed.

Multithreading in PHP
Multithreading in PHP I am working on windows. I have built a twitter application using the twitter API which periodically checks for new tweets as well as allows users to update their status. I have written separate PHP files for reading (reader.php) and writing tweets (writer.php). The only problem is how do I periodically read the tweets. There are a few ways which I can think of - 1) Use a time-based job scheduler (like Cron) to periodically run the reader.php. How do I do this? 2) Use multithreading to run both reader and writer.php and use a timer function in reader.php Suggestions? Since you are working within Windows, you probably won't be able to use cron very easily. You can however, use the task scheduler. See this link for step-by-step instructions. Another option is to use some kind of job queuing system. The Zend Server Job Queue has the ability to schedule recurring
Java - Multithreading !
Java - Multithreading ! If a thread holds a lock , what happens when the thread needs to enter another critical section controlled by the same lock? nothing: the system is able to determine which thread holds the lock to avoid a thread blocking itself. Intrinsic locks (synchronized) in Java are reentrant, thus the JVM will recognize that the current thread already holds this lock and it will proceed. There are also explicit locks, that are reentrant. If a lock is not reentrant, you could for instance not use recursive methods. If a thread holds a lock then it can enter any methods(synchronized or non synchronized), but if any other thread wants to call a method then the methods should be non synchronized or it should wait to acquire the lock if it tries to call a synchronized method
multithreading in vb.net
multithreading in vb.net what is multithreading and how do i do it in vb.net? Here's a tutorial to get you started. As for what it is, this is from Wikipedia: In computer science, a thread of execution results from a fork of a computer program into two or more concurrently running tasks. The implementation of threads and processes differs from one operating system to another, but in most cases, a thread is contained inside a process. Multiple threads can exist within the same process and share resources such as memory, while different processes do not share... of a solution across multiple CPUs (or cores). You can add multithreading to your .NET application by working with the Thread class. Note that making multi-threaded stuff work usually requires careful synchronization handling, using concepts like mutexes and semaphores. Without this, you can run into various

MultiThreading and Deadlock
MultiThreading and Deadlock In which situations we can do the multithreading and deadlock concepts. can give some examples Your question is too vague... for .NET multithreading, I think this is the best thing to read http://www.albahari.com/threading/ Multi-threading is basically the use of threads, which are certain entities which have access to the same memory space in your process, to run different parts of your process concurrently. However, concurrent programming is hard, complicated, and dangerous. Deadlock is one of the dangers which arise from that, which means that two threads are waiting on each other to finish a task, ending up in a lock. Suppose you are waiting for me to give you $5 before you give me $5, and I am doing the same. We're both waiting for each other, thus nothing is going to happen. Like I said, this is a very complicated subject, definitely not something
Multithreading and booleans
Multithreading and booleans Hi Everyone, I have a class that contains a boolean field like this one: public class MyClass { private bool boolVal; public bool BoolVal { get { return boolVal; } set { boolVal = value; } } } The field can be read and written from many threads using the property. My question is if I should fence the getter and setter with a lock statement? Or should I simply use the volatile keyword and save the locking? Or should I totally ignore multithreading since getting and setting boolean values atomic? regards, volatile alone... suspect, or know, that this field will be written to and read from multiple threads, I would definitely add locking and volatile to the mix. Note that I'm no expert in multithreading, I'm able to hold my own, but I usually program defensively. There might (I would assume it is highly likely) that you
Ehcache & MultiThreading
Ehcache & MultiThreading Does ehcache support multi-threading by default or does it require any configuration changes? On multi threading my application with Ehcache i found that the DB hit count is actually increasing i.e. there is no global cache available for all the threads despite the fact that my cache's are all Singletons. Any suggestions? It sounds to me like you're creating CacheManagers per-thread, rather than creating one and passing it around. e.g. CacheManager singletonManager = CacheManager.create(); // and pass this around This may help answer your question, from the FAQ: Is it thread safe to modify Element values after retrieval from a Cache? Remember that a value in a cache element is globally accessible from multiple threads. (It is inherently not thread safe to modify the value.* It is safer to retrieve a value, delete the cache element and then reinsert

Multithreading in Uniprocessor
Multithreading in Uniprocessor I wish to know how multi-threading in a uniprocessor system is helpful my doubt is when you create the thread it is going to take the execution time slice from the main thread only and other thing is scheduling of threads (context switch between the threads... off the GUI into another thread, you can still have your GUI responsive despite a lot of computation somewhere else in your program. Multithreading was invented because it was found that most of the time a program is waiting for I/O. If the processor is shared among other programs this idle time can be made use of. Even though some processor time is spent managing thread/processes this practice was found to be more productive than running one program at a time to the end in sequence. With Uniprocessor systems, multithreading helps in sharing the CPU among multiple tasks so that no one task

Google Tech Talk December 13, 2010 Presented by Steven Swanson. ABSTRACT Fast non-volatile memories
Engineering a Fast PCIe-Attached Storage Array for Next-Generation Non-Volatile Memories
Google Tech Talk December 13, 2010 Presented by Steven Swanson. ABSTRACT Fast non-volatile memories with performance comparable to DRAM (whether it is PCM, the Memristor, scalable MRAM, or something else) will be upon us in a few short years. These technologies are around 10000 times faster than spinning disks and 1000 times faster than flash in terms of latency, and they offer enormous gains in bandwidth as well. Fully leveraging these technologies will require far-reaching changes in the way that programmers use and reason about persistent data and how systems manage persistent storage. I will describe a prototype high-performance storage system called Moneta that we have developed in the Non-Volatile Systems Laboratory at UCSD. Moneta provides a window into the future storage systems by using DRAM to emulate advanced non-volatile memories. In building Moneta, we have found that existing system and application software designed for a world of slow disks is a poor fit for fast devices like Moneta. In response, we have co-designed the Moneta hardware interface and the Moneta driver to increase bandwidth by over 10x for small requests, reduce latency to just 12us for 4KB accesses, and allow Moneta to sustain 1.1 Million IOPS. We compare Moneta to a range of storage devices based on disks, flash, and advanced non-volatile memories, and find that leveraging the speed of fast non-volatile memories will require significant changes in file systems and applications.

voxels & radiosity, part 3
So I upgraded my computer and in the process went from single-core to dual-core CPU. Being the nerd I am I immediately thought of my old voxel engine and how it might benefit from multithreading. I finally got around to testing it. There haven't really been many changes since part 2. Here I only render the floor -- I remember having a bit too much trouble getting radiosity to work correctly with two layers of these heightmapped voxels so I've chopped the ceiling off for now. What you have here is a very coarse radiosity lightmap -- each tile of light covers an area of 20x20 pixels on the heightmap. Computing three passes (on one thread) on a heightmap of about 800x800 pixels took this 2.6 GHz AMD 5050e a minute or two -- with higher detail it would easily take hours. I haven't really done much with multithreading yet, the way it works now is one thread handles "everything" while the other thread calculates the lightmap, thus you can see the result of each pass applied in "real-time" as you move around. It's quite neat and I'm sure there are many other ways to take advantage of multithreading on a project like this. I haven't tried it, but I guess it would be possible to split the lightmap into two parts and have the two threads process each part individually.. I'm not sure if you'd get artifacts from that or not, but I think that as long as you just combine the results after each pass it should work fine. That way a quad-core could render the radiosity almost in real-time ...

Scalability On Demand
TechCrunch50 Sept 2008 - San Francisco Programming for multicore systems is difficult; programming for distributed systems is even more difficult; programming for real-time, distributed systems is even harder still. Having to implicitly deal with threads, synchronization, locking etc demands a whole new skill set and way of thinking. Connective Logic have produced a software development platform called Blueprint that hides the threading and distributed nature of the software application from the programmer - the programmer develops using a 'single virtual machine' concept. The resultant application will run efficiently on a single multicore machine or a network of machines using the same code base. The platform consists of a Graphical Front End, a code generator (currently C++ but .NET language support soon) and a real-time, distributed runtime. Our primary aim is to simplify the development of multicore/manycore software applications and to allow the developer to build scalable, performant apps without having to learn new multithreading skills. This video is a very short intro to Blueprint and it's capabilities. We are actively looking for beta testers - www.connectivelogic.co.uk

The PC's in order of appearance: ~1995 Pentium Pro 200 Mhz with 128 MB RAM, 6 GB HD ~1999 Pentium III Coppermine 800 Mhz with 512 MB RAM, 20 GB HD ~2004 Athlon 64 2000+ @ 2.0 Ghz with 1 GB RAM, 160 GB HD ~2007 Core 2 Duo @ 2.0 Ghz with 4 GB RAM, 320 GB HD ~2010 Core i5 750 @ 3 Ghz with 4 GB RAM, 2x 1 TB HD Used HyperPi for the last two computers to take advantage of multithreading. Taking that into account my newest computer seems to be about 200x faster than the old Pentium Pro at these operations (4 threads in 1.3 seconds vs. 1 thread in 1 min+). It is also approx. 50x faster per core, despite the fact that it is only a 15x clock speed increase over the Pentium Pro. Stay at the end to see the web browsing experience with the Pentium Pro PC :) Also note the evolution of CPU heat sinks along the way! Let me know if you have any questions! Thanks!

Barry's experimental programming language
A 6 minute demonstration video of my experimental programming language. The project is at quite an early stage now, but here are a few features of the language: * all subroutines are anonymous closures * powerful static type checking and type inference * synchronous multithreading via pipes (supports generators, co-routines, & more) * automatic garbage collection (not yet implemented) * indent-delimited blocks, strings and comments This video is just an initial take to get a rough idea across, but it may be a while before I get a chance to prepare something better. Although you may have to look very closely to notice, the video demonstrates the anonymous closures, pipes/generators/coroutines and indent-delimited blocks and comments. The garbage collection is not yet implemented. The type inference is experimental, especially the generic subroutine support (ie. just because I passed an int list to the subroutine doesn't mean it's an int list subroutine).

Colony Demo
Colony is a highly parallel optimized crowd simulation technique. Tens of thousands of units are simulated using a novel ray-casting technique. This is achieved by utilizing TBB to distribute our work across multiple threads and multiple frames and utilizing SIMD to ensure further instruction-level parallelism.

Intel Parallel Studio XE Array Building Blocks Demo
Mike McCool gives a demonstration of Array Building Blocks at SC10 in New Orleans. Array Building Blocks is part of the Intel Parallel Studio XE Suite of tools. Intel Parallel Studio XE 2011 and Intel C++ Studio XE 2011 unite development tools for unprecedented application performance and code robustness for the latest generation of multicore processors. Intel® Parallel Studio XE combines Intel's industry-leading C/C++ and Fortran compilers; performance and parallel libraries; error checking, code robustness, and performance profiling tools into a single suite offering. This helps boost application performance and increase the code quality, security, and reliability needed by high-performance computing and enterprise applications. At the same time, the suite eases the procurement of all the necessary tools for high performance, and simplifies the transition from multicore to manycore processors in the future. Intel C++ Studio XE offers the same suite of tools without the Fortran compiler for developers who only need the C++ compiler. For more info on these tools visit: software.intel.com

The Santa Claus Problem - Thread Synchronization
A thread synchronization computer programming problem and a solution using semaphores and mutexes. The solution shown in this video is a slightly modified version of the solution found in The Little Book of Semaphores by Allen B. Downey, which is an excellent free book on semaphores with lots of example problems and solutions. greenteapress.com The solution here is slightly over-constrained compared to that shown in Downey's book, but I find this version somewhat cleaner and more satisfying for reasons I can't quite articulate :) How the visualization should proceed under other circumstances, such as when the 9th reindeer returns to the north pole, is left as an exercise for the viewer.
