If your application does not need these functions then you can disable them using the S4E directive no_init_term. The termination function will be called before unregistration begins.These functions can be used to do one time setup and teardown of your extension to prepare it for use.

Are we doing something wrong or has this bug not yet been fixed? If, however, T3 were the first to initialize TBB scheduler, then the market would have a limit of 15 workers, and all arenas would get as many slots as they requested, Prev Intel® Trace Collector API Next VT_initialize Support Terms of Use *Trademarks Privacy Cookies Publications Intel® Developer Zone Newsletter Intel® Parallel Universe Magazine Look for us on: Facebook Twitter Google+ This will help future proof your extension against any runtime updates in Marmalade. http://www.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.ikjc100/ikjc10013.htm

Again, for platforms where loading doesn’t make sense there will just be an unregistration step. Whether for good or for bad, in both cases absolutely nothing happens, except for a refcount on the local task dispatcher being incremented. Thus it is completely well-formed usage when an application thread initializes TBB task scheduler, allocates a task, enqueues it, and immediately terminates the scheduler. Task dispatcher associated with this master thread is created.

  1. Threads creation is postponed until the first task is spawned or enqueued (in particular this happens when a TBB parallel algorithm is invoked).
  2. Similarly it will generate stubs for MyExtensionInit_platform and MyExtensionTerminate_platform for each platform.The initialization function will be called when an extension is first loaded and registered with the Marmalade
  3. Starting with TBB 2.2 any operation with tasks (allocation, spawning, enqueuing, and destruction) will initialize task scheduler automatically, if this has not been done in this thread yet.
  4. Workers distribution All right, we’ve already made that far, and there’s just one more situation possible during execution phase that remains unvivisected.

See the description of functions: VT_traceon VT_traceoff VT_tracestate With the Intel® Trace Collector configuration mechanisms described in Filtering Trace Data, the recording of state changes can be controlled per symbol or

In non-MPI applications it may be necessary to start and stop Intel® Trace Collector explicitly. At the end of the registration process the initialization function is called.If the initialization function returns S3E_RESULT_ERROR then extension loading will fail.

As I noted in my previous blog introducing a major task scheduler extension – support for task and task group priorities, TBB has been steadily evolving ever since its inception. If your application requires a higher thread level, then either use MPI_Init_thread() instead of VT_init() or (if VT_init() is called for example, by your runtime environment) set the environment variable VT_THREAD_LEVEL For site or software product issues contact support.) Please sign in to add a comment. Very useful.

Often this happens only when the application completes. As the default concurrency level (which allows for full hardware resources utilization) is normally what you want anyway, this auto-initialization deficiency is rarely an issue. In case of auto-initialization, local task dispatcher will be destroyed only when its thread exits. But what happens if a thread already having TBB scheduler initialized, creates another task_scheduler_init object?

See this blog for more details. When the last task_scheduler_init object created by this thread is destroyed, the actions opposite to initialization events take place, though not exactly in the mirror fashion. For example, your extension may be known to work for Android devices running Android M, but for earlier versions it may not make sense to use the extension.  The termination function But this workaround in its turn has substantial limitations.

To facilitate the discussion I’ll be referring to the following diagram that summarizes major internal components constituting TBB task scheduler.   If you want some more background information why TBB arrived Before then the whole thread pool was allocated at the moment of RML server instantiation. Variable Documentation SystemState osg::GlobalSystemState = Startup Definition at line 81 of file OSGBaseFunctions.cpp. Disregarding whether its previous arena was destroyed or remained covertly alive, the master thread can repeat scheduler initialization anew.

At last, before saying good bye, I’d like to highlight the fact that this blog describes mechanics of TBB as it is in its version 3.0 Update 6. During its destruction sequence it notifies its arena that the master thread is leaving. Thus with the current TBB version it is impossible to change concurrency level of parallel algorithms started from a thread after this thread has initialized the scheduler.

Actually it’s pretty easy. For the sake of illustration consider the following example. This means that auto-initialization, with all its convenience, may restrict your ability to control concurrency of parallel computations. If, however, T4 starts its parallel work after T1 finished its, then RML will additionally create only 2 workers, as the pending cumulative request is that of T4, and it is

If the function returns S3E_FALSE then the extension will not be available for the current platform. The second kind of situation is possible because of the following scheduler dispatch loop peculiarity. Since you’ve certainly noticed that the current design imposes some restrictions that have potential of becoming burdensome in some situations (even if only infrequently), there will surely be changes in the This, however, does not mean that worker threads have already left the arena.

Normally you do not see this problem, but if the application exits or the module that used TBB is unloaded immediately after the last parallel algorithm completion, it may, well, crash… Otherwise they are optional, and 0 or a NULL pointer may be used.
