• What is the difference between a process and a thread

  - by James Fassett

  What is the technical difference between a process and a thread? I get the feeling a word like 'process' is over used and there is also hardware and software threads. How about light-weight processes in languages like Erlang? Is there a definitive reason to use one term over the other?

• FAQ: Creating a new LDOM domain

  - by Owen Allen

  I got a question about creating LDOM domains: "I have a Server Pool set up, and I need to create a secondary LDom domain on a machine in the pool. When I click on the machine, though, the 'create logical domain' command is grayed out. The machine still has available CPU threads and free RAM. What's going on?" This one has an easy answer. In a Server Pool, the Create Logical Domain action is under the pool's actions, rather than the individual machine's actions. This is because the Server Pool decides where to put the new domain based on the Server Pool's placement policy. So, in this case, you need to select the Server Pool in the Assets section, and then create the new domain from there.

• performSelector:onThread: when the target thread is blocked

  - by psychotik

  Yes, I'm being lazy. What happens when I call performSelector:onThread:... and pass in a thread that's currently blocked (on synchronous I/O, for instance)? Does the selector just get queued to be executed later?

• C++0x thread interruption

  - by Nicola Bonelli

  According to the C++0x final draft, there's no way to request a thread to terminate. That said, if required we need to implement a do-it-yourself solution. In your opinion, what's the best solution? Designing your own cooperative 'interruption mechanism' or going native?

• OGNL thread safety

  - by Dewfy

  I'm going to reuse OGNL library out of Struts2 scope. I have rather large set of formulas, that is why I would like to precompile all of them: Ognl.parseExpression(expressionString); But I'm not sure if precompiled expression can be used in multi-thread environment. Does anybody knows if it can be used?

• C++ thread to separate process

  - by silverbandit91

  Is there any way I can have a thread branch off into its own independent process? I know there's the CreateProcess function but as far as I can tell, you can only run external applications with it. Is what I'm asking for at all possible?

• UI Thread .Invoke() causing handle leak?

  - by JYelton

  In what circumstances would updating a UI control from a non-UI thread could cause the processes' handles to continually increase, when using a delegate and .InvokeRequired? For example: public delegate void DelegateUIUpdate(); private void UIUpdate() { if (someControl.InvokeRequired) { someControl.Invoke(new DelegateUIUpdate(UIUpdate)); return; } // do something with someControl } When this is called in a loop or on timer intervals, the handles for the program consistently increase.

• Looking for a simple alternative to Thread.Sleep

  - by George

  HI, During the development of my app, I was using Thread.Sleep to give our external devices some time to adjust to settings before making queries, as they are quite old and slow. I now want to replace these with something a bit more stylish and correct. Does anyone have a simple way to "wait" for a device rather than sleep, bearing in mind the device does not let us know when it is ready, so a wait is about as good as we can do !?? Regards, George.

• Critical section initialization when creating thread-safe singleton (C++)

• Is this technically thread safe despite being mutable?

  - by Finbarr

  Yes, the private member variable bar should be final right? But actually, in this instance, it is an atomic operation to simply read the value of an int. So is this technically thread safe? class foo { private int bar; public foo(int bar) { this.bar = bar; } public int getBar() { return bar; } } // assume infinite number of threads repeatedly calling getBar on the same instance of foo.

• Counting context switches per thread

  - by Sarmun

  Is there a way to see how many context switches each thread generates? (both in and out if possible) Either in X/s, or to let it run and give aggregated data after some time. (either on linux or on windows) I have found only tools that give aggregated context-switching number for whole os or per process. My program makes many context switches (50k/s), probably a lot not necessary, but I am not sure where to start optimizing, where do most of those happen.

• Serialized task distribution: use thread or epoll?

  - by hpsmouse

  Now I'm in such a situation that there is a group of predefined tasks for multiple clients to do(any client can take any task). When a client connects to the server, server choose a task from the uncompleted tasks and send it to the client. It takes a while for the client to finish the task and send the result back to the server. Since a task should be sent to only one client, server should process requests in a serialized way. Now I have two plans to do it: create a thread for each client connection and all the threads take turns accessing the task pool, or use epoll listening on all the connection and process for each event of clients. Which one is better for the job? Or is there any other ideas? The server will be run on a multi-core machine.

• Trying to link my project with Boost.Thread using CMake

  - by wowus

  When I link Boost.Thread to my boost_test executable, it gives me make[2]: *** No rule to make target `/usr/lib64/libboost_thread-mt.so', needed by `gogo/test/test_boost'. Stop. when I make it. Here's the offending CMake code, what am I doing wrong? add_executable(boost_test boost_test.cpp) add_test(boost_test boost_test) # Boost auto-links for MSVC, so we exclude it. if(CMAKE_COMPILER_IS_GNUCXX) target_link_libraries(test_boost #LINK_INTERFACE_LIBRARIES ${Boost_THREAD_LIBRARY} ) endif()

• Static method,new thread performance question

  - by ylazez

  Hey guys i just have two questions about two methods used in many controllers/servlets in my app: 1-what is the difference between calling a static method in a util class or a non static method (like methods dealing with dates i.e getting current time,converting between timezones), which is better ? 2-what is the difference between calling a method(contain too many logic like sending emails) in the controller directly or running this method in a different thread ?

• static thread function access non-static class member in C++

  - by user397390

  Class Test{ int value; static void* thread_func(void* args){ value++; } void newthread(){ pthread_create(&thread_func,...); } } I'm trying to create a thread in Class Test. Therefore compiler forces me to make thread_func static. However I cannot access the non-static member "value" anymore. It says: invalid use of member 'Class::value' in static member function Is there a way around it?

• C++ Win/Linux thread syncronization Event

  - by JP

  Hello I have some code that is cross-platform by unsing #ifdef OS, I have a Queue protected by a CriticalSection on Windows, and by a pthread_mutex_t on Linux. I would like to implement a Wait(timeout) call that would block a thread until something has been enqueued. I though about using WaitForSingleObject on windows but it don't seem to support CriticalSection. Which Win32 and which Linux functions should I use to Wait and Signal for a condition to happen. Thank
