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. Resetable for other hosts/targets.
Parallel compilation	Supports your build by appropriately allocating files to available processors to take advantage of multicore 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 9.1 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 don’t 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).
Simplified installation	Streamlined, simplified complete installation for a seamless 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. Visit the Support Resources pageto learn more!
Processor Support	The addition of support for Intel® Atom™ processors continues to future-proof your investment with 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. For more details, see the Release Notes.

	Multi-Threaded Application Support, including OpenMP* 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 best utilizes the processor’s capabilities for cache and memory accesses, SIMD instruction sets, and for multiple cores. This revolutionary capability, new in Version 10, combines vectorization, parallelization and loop transformations into a single pass which is faster, more effective and more reliable than prior discrete phases.
	Interprocedural Optimization (IPO)dramatically improves performance of small- or medium-sized functions that are used frequently, especially programs that contain calls within loops. The analysis capabilities of this optimizer can also give feedback on vulnerabilities and coding errors, such as uninitialized variables or OpenMP API issues, which cannot be detected as well by compilers which rely strictly on analysis by a compiler front-end.
	Profile-guided Optimization (PGO) improves application performance by reducing instruction-cache thrashing, reorganizing code layout, shrinking code size, and reducing branch mispredictions.

	Quadruple precision REAL data type REAL(16)
	STRUCTURE, RECORD, UNION, MAP syntax for user-defined types
	Directives and functions to enhance mixed-language application development
	Binary stream I/O
For a complete list of language features, see the product documentation. The Intel Visual Fortran Compiler 10.0 for Windows also enhances programmer productivity with features such as:
	Run-time array and string bounds checking
	Cross-file procedure interface checking
	Run-time uninitialized variable detection
	Error traceback with file name and line number
The compiler also features extensive compatibility with Compaq Visual Fortran* including language extensions, predefined modules, and library routines.

Intel® Visual Fortran Compiler 10.1, Professional and Standard Editions for Windows*

	OpenMP* is the industry standard for portable multithreaded application development. It is effective at fine-grain (loop-level) and large-grain (function-level) threading. OpenMP directives are an easy and powerful way to convert serial applications into parallel applications, enabling potentially big performance gains from parallel execution on multi-core and symmetric multiprocessor systems.
	Auto Parallelization improves application performance on multiprocessor systems by means of automatic threading of loops. This option detects parallel loops capable of being executed safely in parallel and automatically generates multithreaded code. Automatic parallelization relieves the user from having to deal with the low-level details of iteration partitioning, data sharing, thread scheduling, and synchronizations. It also provides the performance benefits available from multiprocessor systems and systems that support Hyper-Threading Technology (HT Technology).

Vectorization automatically parallelizes code to maximize underlying processor capabilities. This advanced optimization analyzes loops and determines when it is safe and effective to execute several iterations of the loop in parallel by utilizing MMX™, SSE, SSE2, SSE3, SSSE3, and SSE4 instructions. Figure 1 is a graphical representation of a vectorized loop that shows four iterations computed with one SSE2 operation.		Figure 1. The Vectorizer in action
Use vectorization to optimize your application code and take advantage of these new extensions when running on Intel® processors. Features include support for advanced, dynamic data alignment strategies, including loop peeling to generate aligned loads and loop unrolling to match the prefetch of a full cache line.

		Next-generation data-intensive application developers benefit from dramatic performance optimizations using the Intel compilers to decrease latency and processing times, while also allowing software architects to add additional features without unacceptable impacts to performance.

		Scientific, research, and related applications benefit from fast compile times, high-performance execution, and solid technical support. Numerically intensive software can make excellent use of the parallelism in Intel processor-based platforms.
