英特尔TBB(Threading Building Blocks)是一个并行编程框架,提供了一套用于多核处理器的并行算法和数据结构。Scalable_allocator是TBB中的一个内存分配器,它提...
什么是tbb::scalable_allocator英特尔线程构建模块实际上是引擎盖下呢?它肯定是有效的.我刚用它来采取25%的折扣的应用程式的执行时间(并看到在CPU利用率从〜200%4核系统上增加至350%),通过改变单个std::vector<T>给std::vector<T,tbb::scalable_allocator<T> >.另一方面,在另一个应用程序中,我看到它将...
tbb::memory_pool 基于与 tbb::scalable_allocator 相同的内部机制。因此,一旦内存池最初获取了内存(在您指定的情况下,也是从 tbb::scalable_allocator 获取),它将使用相同的机制在线程之间分配和重复使用内存。即它是可扩展的,并尽可能避免全局锁。尽管如此,由于内存仍然是共享资源,一些线程同步是不可避免的。具体...

It would not be a problem if we use tbb::scalable_allocator for _all_ our allocations, but we use native thread-safe malloc/new for our product and third party allocations. Just for the small structure we needed better performance/memory utilization and used boost::pool....
Aspects of the subject matter described herein relate to memory management. In aspects, a hierarchical, customized memory allocator may be created that allocates memory to memory consumers. The memory allocator may use a data structure to classify blocks of memory at each level in the hierarchy ...
