Post by Aave » Oct 23, Multithreading can be hard to implement correctly as hard-to-find bugs such as race conditions can arise. However, with highly parallel tasks e. Also, as in the modern world, the trend seems to be increasing the number of cores instead of gigahertzs, in a computationally intensive task parallel processing is really the only option. However, performance isn't the only reason to go multithreaded - it can improve user experince if tasks are performed in the background. Also audio analyzers work in their own thread so e.
Post by Landeel » Oct 23, I am working on a game engine that uses multithreading. A thread for rendering, a thread to handle user input, a thread to sort sprites for the next frame, a thread to handle enemy AI, a thread for filtering images at load time.
Using multiple threads have improved a lot the speed, simply because non-dependant tasks can be done simultaneously.

Simplified coding of remote procedure calls and conversations In some applications it is easier to code different remote procedure calls and conversations in separate threads than to manage them from the same thread.
Simultaneous access to multiple applications Your BEA Tuxedo clients can be connected to more than one application at a time. Reduced number of required servers Because one server can dispatch multiple service threads, the number of servers to start for your application is reduced.
This capability for multiple dispatched threads is especially useful for conversational servers, which otherwise must be dedicated to one client for the entire duration of a conversation. For applications in which client threads are created by the Microsoft Internet Information Server API or the Netscape Enterprise Server interface that is, the NSAPI , the use of multiple threads is essential if you want to obtain the full benefits afforded by these tools.

Add a Solution. Sergey Alexandrovich Kryukov Aug am. Not a correct question: it depends on what you are writing. And why? Do you think having no threads would make you life easier? It also depends on what do you mean "without threads". You could say "single-threaded". There cannot be zero threads.

First, you always have at least one threads. Adding more threads in many cases is not your choice, it is indirectly defined by the requirements. For example, imagine that you got some requirements for numerical simulation: you need to calculate trajectories of some moving bodies more exactly, worlds lines. If the problem is solvable at all, you always can do it one thread, and it's likely the best option.
Now, imagine you need to output some intermediate locations of bodies as motion progresses and give the user the power to stop motion or change some parameters on the fly. Use thread-safe wrappers. The deadlock happens when one thread is waiting for the resource of other thread, but the other thread still waiting for the resource which keep by the first thread.
Inside multiple thread when we use this one, it will make the performance go down, you have to make it as small as you can, only use it when you have to use. Keep the number of threads as a input parameter of main function if you can. And when something happens, we can set the number of threads to 1, and we have a single thread to test and debug.
However, this way just supports finding the business bugs, and the bugs of single thread. If we got the problem with multiple threads like each threads have conflict with each other, this way is not helpful. Add useful log to the thread. The log is so powerful, try to put the log at the position which you can see the running flow, and you can see the whole flow. Write log when the exception happen, I hate to catch java. Exception but if you want the thread keep going on the next data, you have to catch it, to make sure everything is under control.
At the first time running we can put a lot of log info to your source code, and when everything runs stably, you can remove them. Use the tool to test. When multiple threads are running, you can use the tool to see how the threads running, which one is running, which one is not, the status of each thread, and so on.
