Features

Features

	Microsoft Visual Studio 2005 Premier Partner Edition is included in commercial license purchases to provide a complete Fortran development environment for developers who do not use Visual Studio (not included in evaluation or student versions). Already have Visual Studio? Intel Visual Fortran Compiler for Windows is compatible with it.
	Multi-Threaded Application Support, including, new in 11.0, OpenMP 3.0 (data- and now task-parallelism), and auto-parallelization for simple and efficient software threading.
	Auto-vectorization parallelizes code to utilize the Streaming SIMD Extensions (SSE) instruction set architectures (SSE, SSE2, SSE3, SSSE3, and SSE4) of our latest processors.
	High-Performance Parallel Optimizer (HPO) restructures and optimizes loops to ensure that auto-vectorization, OpenMP, or auto-parallelization make best use of cache and memory accesses, SIMD instruction sets, and multiple cores. Compiles in a single pass, improving compile-time and producing more reliable code.
	Interprocedural Optimization (IPO) dramatically improves performance of small- to mid-sized functions, especially in programs containing calls within loops. IPO analysis gives feedback on vulnerabilities and coding errors, such as uninitialized variables or OpenMP API issues, which cannot be detected as well by other compilers.
	Profile-guided Optimization (PGO) improves application performance by reducing instruction-cache thrashing, reorganizing code layout, shrinking code size, and reducing branch mispredictions.
	Intel® Math Kernel Library includes optimized and scalable math routines for maximizing performance, and seamlessly provides forward scaling from current to future many-core platforms.
	New, integrated, simplified installation gets you going with all capabilities quickly and easily. Simplified ‘custom’ install makes it easy to identify just the components you want.
	Ongoing Premier Support now includes online community-support forums to speed information flow, in addition to private, password-protected accounts. Technical support, interactive issues management, access to technical and application notes, product updates and more with every commercial and academic license.

New in This Release

Feature	Benefit
Visual Studio Support	Developers with Microsoft* Visual Studio* 2005 or 2008 can protect their investment by just plugging in Intel® Visual Fortran Compiler for Windows. For commercial licensees who do not use Visual Studio, the Professional Edition includes Microsoft Visual Studio 2005 Premier Partner Edition and, of course, offers command-line usage. The Premier Partner Edition is not included in evaluation or student licenses. Please see System Requirements for details.
VNI’s IMSL Fortran Library for Windows	The gold standard for numerical computing, IMSL provides over 1,000 mathematical and statistical algorithms covering numerical optimization, nonlinear equations, LAPACK, BLAS and more.
Compiler & Debugger
More Fortran 2003 Support	Additional support includes ENUMERATOR, IEEE Floating-Point Exception Handling, ALLOCATE extensions, array constructor changes, and more to bring your Fortran apps closer to the standard. These join C interoperability features introduced in the last release to make it easier to develop mixed-language applications.
*OpenMP 3.0**	OpenMP raises the parallelism abstraction away from the API, simplifying threading and making code more portable. Previously limited to loop-based data-parallelism, the new 3.0 standard simplifies both data and task parallelism.
SSE2 enabled by default	Take advantage of new Intel Streaming SIMD Extensions – automatically – through the compiler. No messy low-level coding to get the most from Intel processors. Resettable for other hosts/targets.
Parallel compilation	Supports your build by appropriately allocating files to available processors to take advantage of multi-core processors and speed you through your edit/compile/debug cycle.
Optimization Reports	More detailed optimization diagnostics for users who want to use our advanced optimizations to help the compiler do a better job of tuning their applications. The new VTune™ Analyzer can filter optimization reports to help guide optimization efforts.
Intel® COM Server Wizard	An update of the popular feature from Compaq* Visual Fortran that enables you to create Fortran applications that are usable from the Microsoft .NET* managed code environment.
Static Verifier	Find and analyze source file issues. Diagnostics include issues with OpenMP directives, boundary violations, memory corruptions, memory leak, buffer overflow, and uninitialized memory.
Intel® Math Kernel Library (Intel® MKL)
New “layered” architecture	The new architecture provides maximum support for different development environment configurations and processors in a single package.
New threading layer	Link to the version of this layer that matches your development environment, and rest assured that Intel MKL will not have threading incompatibilities with the threading in your application.
Discrete Fourier Transform Interface	The DftiCopyDescriptor function has been added for convenience when using the FFTs. The size of statically linked executables calling DFTI has been reduced significantly, and complex storage is now available for real-to-real transforms.
LAPACK enhancement	The capability to track and/or interrupt the progress of lengthy LAPACK computations has been added. A function called mkl_progress can be defined in a user application, which will be called regularly from a subset of the MKL LAPACK routines.
VML extensions	With performance in mind, all VML functions are now threaded. And a new “Enhance Performance” mode is offered for applications where math-function inaccuracies do not dominate parameter inaccuracies (e.g., Monte Carlo simulations and media applications).
Sparse BLAS extensions	Improvements include threaded level-3 sparse BLAS triangular solvers and support for all data types (single precision, complex and double complex).
Other Features
Simplified installation	Streamlined ‘complete’ installation for a seamless, near one-step installation of all components.
New Online Support Community	Our enhanced, online community-support forums and knowledge-base search capabilities help you find answers more quickly. This is in addition to private, password-protected accounts available with Premier Support.
Processor Support	The addition of support for Intel® Atom™ processors serves as an example of our commitment to future-proof your investment with the assurance of support for each successive generation of processors. That's a key advantage in a world where new hardware platforms come to market with awesome speed.

System Requirements

Architecture Terminology

Intel® compilers and libraries support three platforms (general combinations of processor architecture and operating system type). This section explains the terms that Intel uses to describe the platforms in its documentation, installation procedures, and support site.

IA-32 Architecture refers to systems based on 32-bit processors generally compatible with the Intel Pentium® II processor (for example, Intel® Pentium® 4 processor or Intel® Xeon® processor), or processors from other manufacturers supporting the same instruction set, and running a 32-bit operating system.

Intel® 64 Architecture refers to systems based on IA-32 architecture processors that have 64-bit architectural extensions (for example, Intel® Core™2 processor family), and are running a 64-bit operating system such as Microsoft Windows XP* Professional x64 Edition, or Microsoft Windows Vista* x64. If the system is running a 32-bit version of the Windows operating system, then IA-32 architecture applies instead. Systems based on AMD* processors running a 64-bit version of Windows are also supported by Intel compilers for Intel® 64 architecture applications.

IA-64 Architecture refers to systems based on the Intel® Itanium® processor running a 64-bit operating system.

Native and Cross-Platform Development

The term "native" refers to building an application that will run on the same platform that it was built on; for example, building on IA-32 architecture to run on IA-32 architecture. The term "cross-platform" or "cross-compilation" refers to building an application on a platform type different from the one on which it will be run; for example, building on IA-32 architecture to run on Intel® 64 architecture systems. Not all combinations of cross-platform development are supported, and some combinations may require installation of optional tools and libraries.

The following table describes the supported combinations of compilation host (system on which you build the application) and application target (system on which the application runs):

Host \ Target	IA-32	Intel® 64	IA-64
IA-32	Yes	Yes	Yes
Intel® 64	Yes	Yes	Yes
IA-64	No	No	Yes

Minimum System Requirements

A PC based on an IA-32 architecture processor supporting the Intel® Streaming SIMD 2 Extensions (Intel® SSE2) instructions, or a PC based on an Intel® 64 architecture processor or 64-bit AMD* Athlon* or Opteron* processor, or a PC based on an IA-64 architecture (Intel® Itanium) processor
