| Changeset | 0029935: Foundation Classes - introduce OSD_ThreadPool class defining a thread pool New class OSD_ThreadPool has been introduced to define a Thread Pool for multi-threading algorithm. Thread Pool assigns a serial number for each thread allowing Multi-Threading algorithm to allocate thread-local storage variables as an array whose size is the same as the number of threads. OSD_ThreadPool also redirects exceptions to a thread calling parallel execution and consistently initializes FPE exception handling. New class Standard_Condition provides a platform-independent tool similar to Event in WinAPI. A new auxiliary function Standard_Atomic_CompareAndSwap() has been introduced for performing atomic compare and swap of integer number. Standard_Atomic_Increment/Standard_Atomic_Decrement fallback implementation using ASM code for x86 processors for GCC has been dropped; instead, it is expected that GCC should be properly configured targeting modern x86 architectures. OSD_Signal now declares fFltExceptions as thread_local variable accessible through OSD::ToCatchFloatingSignals() property. Standard_THREADLOCAL macro (wrapping thread_local attribute) has been moved to public header Standard_Macro.hxx. OSD_Parallel::ForEach() has been extended with new optional parameter theNbItems and uses OSD_ThreadPool::DefaultPool(). |
