Intel(R) Threading Building Blocks - Release Notes Version 2.2 ------------------------------------------------------------------------ System Requirements ------------------- Intel(R) Threading Building Blocks (Intel(R) TBB) is available commercially (see http://www.intel.com/software/products/threading) as a binary distribution, and in open source, in both source and binary forms (see http://threadingbuildingblocks.org). When built from source, Intel(R) TBB is intended to be highly portable and so supports a wide variety of operating systems and platforms (see http://threadingbuildingblocks.org for more details). Binary distributions, including commercial distributions, are validated and officially supported for the hardware, software, operating systems and compilers listed here. Hardware - Recommended Microsoft* Windows* Systems Intel(R) Core(TM) 2 Duo processor or Intel(R) Xeon(R) processor or higher Linux* Systems Intel(R) Core(TM) 2 Duo processor or Intel(R) Xeon(R) processor or Intel(R) Itanium(R) processor or higher Mac OS* X Systems Intel(R) Core(TM) 2 Duo processor or higher Hardware - Supported Intel(R) Pentium(R) 4 processor family and higher Intel(R) Itanium(R) processor family (Linux* systems only) Non Intel(R) processors compatible with the above processors Software - Minimum Requirements Supported operating system (see below) Supported compiler (see below) Xcode* tool suite 2.4.1 or higher (Mac OS* X systems only) Microsoft* Internet Explorer* 6.0, or other compatible web browser Adobe(R) Reader(R)* 6.0 or higher Software - Recommended Intel(R) Parallel Studio Intel(R) C++ Compiler 10.0 or higher Intel(R) Thread Checker 3.1 or higher Intel(R) Thread Profiler 3.1 or higher Software - Supported Operating Systems Microsoft* Windows* Systems Microsoft* Windows* XP Professional Microsoft* Windows* Server 2003 Microsoft* Windows* Vista Microsoft* Windows* Server 2008 Linux* Systems Red Hat* Enterprise Linux* 3, 4, 5 (when using Red Hat* Enterprise Linux* 4 with Intel(R) Itanium(R) processors, operating system Update 2 or higher is recommended) Red Hat* Fedora* 10, 11 (not with Intel(R) Itanium(R) processors) Asianux* 3.0 Debian* GNU/Linux* 4.0, 5.0 Ubuntu* 8.04, 8.10, 9.04 SuSE* Linux* Enterprise Server (SLES) 9, 10, 11 SGI* Propack* 5.0 (not with IA-32 architecture processors) Turbolinux* 11 Mac OS* X Systems Mac OS* X 10.5.6 or higher Software - Supported Compilers Microsoft* Visual C++* 7.1 (Microsoft* Visual Studio* .NET 2003, Windows* systems only, deprecated) Microsoft* Visual C++ 8.0 (Microsoft* Visual Studio* 2005, Windows* systems only) Microsoft* Visual C++ 9.0 (Microsoft* Visual Studio* 2008, Windows* systems only) Intel(R) C++ Compiler 10.0 or higher For each supported Linux* operating system, the standard gcc version provided with that operating system is supported, including gcc 3.2 through 4.4 For each supported Mac OS* X operating system, the standard gcc version provided with that operating system is supported, including: 4.0.1 (Xcode* tool suite 3.1.2 or higher) Known Issues ------------ Please note the following with respect to this particular release of Intel(R) Threading Building Blocks. Library Issues - The atomic<long long> and atomic<unsigned long long> templates are not supported when using the Microsoft* Visual C++* 7.1 (Microsoft* Visual Studio* .NET 2003) compiler. - Unhandled exceptions in the user code executed in the context of TBB algorithms or containers may lead to segmentation faults when Intel(R) C++ Compiler 10.x is used with glibc 2.3.2, 2.3.3, or 2.3.4. - To allow more accurate results to be obtained with Intel(R) Thread Checker or Intel(R) Thread Profiler, download the latest update releases of these products before using them with Intel(R) Threading Building Blocks. - If you are using Intel(R) Threading Building Blocks and OpenMP* constructs mixed together in rapid succession in the same program, and you are using Intel(R) compilers for your OpenMP* code, set KMP_BLOCKTIME to a small value (e.g., 20 milliseconds) to improve performance. This setting can also be made within your OpenMP* code via the kmp_set_blocktime() library call. See the Intel(R) compiler OpenMP* documentation for more details on KMP_BLOCKTIME and kmp_set_blocktime(). - In general, non-debug ("release") builds of applications or examples should link against the non-debug versions of the Intel(R) Threading Building Blocks libraries, and debug builds should link against the debug versions of these libraries. On Windows* systems, compile with /MD and use Intel(R) Threading Building Blocks release libraries, or compile with /MDd and use debug libraries; not doing so may cause run-time failures. See the Tutorial in the product "doc" sub-directory for more details on debug vs. release libraries. - In some circumstances an exception thrown during concurrent_vector growth operation may deadlock other threads that also attempt to grow the vector. To prevent the issue, avoid going out of memory and throwing exceptions in constructors of stored objects. - Installer doesn't accept non-commercial serial numbers on Red Hat* Fedora* 11. To install the product on the system use license file provided after registration of the serial number. ------------------------------------------------------------------------ Copyright (C) 2005-2009 Intel Corporation.
