Compatibility
In general, object code and modules compiled with earlier versions of Intel Fortran Compiler for Linux* (8.0 and later) may be used in a build with version 17. Exceptions include:
Stack Alignment Change for REAL(16) and COMPLEX(16) Datatypes
In versions prior to 12.0, when a REAL(16) or COMPLEX(16) (REAL*16 or COMPLEX*32) item was passed by value, the stack address was aligned at 4 bytes. For improved performance, the version 12 and later compilers align such items at 16 bytes and expects received arguments to be aligned on 16-byte boundaries. This change is also compatible with gcc.
This change primarily affects compiler-generated calls to library routines that do computations on REAL(16) values, including intrinsics. If you have code compiled with earlier versions and link it with the version 12 libraries, or have an application linked to the shared version of the Intel run-time libraries, it may give incorrect results.
In order to avoid errors, you must recompile all Fortran sources that use the REAL(16) and COMPLEX(16) datatypes if they were compiled by compiler versions earlier than 12.0.
New and Changed Features
The Intel® Fortran Compiler now supports all features from the Fortran 2008 standard. Moment of inspiration mac download. Additional Fortran 2008 features added in the Intel® Fortran 18.0 release are noted below. Please refer to the Fortran 2008 Standard (PDF) and the proposed draft Fortran 2015 Standard (PDF) if necessary.
Features from Fortran 2008
Features from OpenMP*
Language features for task reductions from the OpenMP* Technical Report 4 : Version 5.0 Preview 1 specifications are now supported.
TASKGROUP now has the TASK_REDUCTION clause.
TASK includes now has the IN_REDUCTION clause. TASKLOOP now has the REDUCTION and IN_REDUCTION clauses.
New monotonic, overlap and lastprivate keywords for OpenMP* SIMD directive:
!$omp ordered simd overlap(overlap_index)
!$omp ordered simd monotonic([var:step]s) !$omp simd lastprivate(conditional:[vars])
For more information, see the compiler documentation or the link to the OpenMP* Specification above.
New and Changed DirectivesIntel Visual Fortran DownloadNew and Changed Compiler Options
Please refer to the compiler documentation for details
For a list of deprecated compiler options, see the Compiler Options section of the documentation.
New -qopenmp Compiler Option replaces -openmp
To enable the OpenMP* feature, use -qopenmp. The compiler no longer accepts the previous spelling -openmp
Enhanced -init=[keyword] Compiler option
The option already allows scalars and arrays to be initialized with ZERO or SNAN. Feature support extends this to HUGE and MINUS_HUGE {+/- largest representable integer or real}, TINY and MINUS_Tiny {+/- smallest representable integer or real}, and INFINITY and MINUS_INFINITY for +/- IEEE Infinity.
All –o* options replaced by –qo* options
All the –o* options deprecated in the previous release have been replaced with –qo* options in this release with one noted exception, there is no change to the –o option for Linux* and macOS* used to name the output file.
A new diagnostic is issued when any now replaced –o option is used. For example:
$ ifort -openmp example.f90
ifort: command line error: option '-openmp' is not supported. Please use the replacement option '-qopenmp'
Options affected:
-offload-attribute-target=<target>
-offload-option,<target>,<tool>,<opts> -[no-]offload[=<arg>] -[no-]openmp -openmp-lib=<arg> -openmp-link=<arg> -[no-]openmp-offload -[no-]openmp-simd -openmp-stubs -openmp-threadprivate=<arg> -openmp-report[=<level>] -openmp-task=<arg> -opt-args-in-regs=<arg> -[no-]opt-assume-safe-padding -opt-block-factor=<arg> -[no-]opt-calloc -[no-]opt-class-analysis -[no-]opt-dynamic-align -[no-]opt-gather-scatter-unroll -[no-]opt-jump-tables=<arg> -opt-malloc-options=<arg> -[no-]opt-matmul -[no-]opt-mem-layout-trans=<arg> -[no-]opt-multi-version-aggressive -[no-]opt-prefetch[=<val>] -opt-prefetch-distance=<arg> -opt-ra-region-strategy[=<arg>] -[no-]opt-report-embed -opt-report-file=<arg> -opt-report-filter=<arg> -opt-report-format=<arg> -opt-report-phase=<arg> -opt-report-routine=<arg> -opt-report-help -opt-report[=<arg>] -opt-report-per-object -opt-streaming-cache-evict=<arg> -opt-streaming-stores=<arg> -[no-]opt-subscript-in-range -opt-threads-per-core=<arg> New -assume contiguous_pointer and -assume contiguous_assumed_shape Compiler options
What is the latest version of adobe flash player for mac. These are new options to assert that all assumed shape arrays and/or pointers have unit stride.
New -check contiguous Compiler option
The -check contiguous compiler option help to diagnose non-contiguous pointer assignment to CONTIGUOUS pointer. The -check all option includes this check. Mac os latest download iso.
New option -fimf-use-svml to force the usage of SVML
https://royalyellow499.weebly.com/blog/madden-nfl-08-mac-download. New option forces use of SVML where currently LIBM is used, for scalar math. This guarantees bitwise-same result of computations made with vectorized code vs computations made with scalar code. With this feature the compiler vectorizes math functions in -fp-model precise FP model and vectorized code produces results consistent with scalar code results.
Compile time dispatching for SVML calls
The compiler default behaviour is changed for SVML functions and a call to cpu-specific SVML entry is performed. Specifying new option -fimf-force-dynamic-target reverts to the previous behavior and dynamic SVML dispatching is used.
New -qopt-zmm-usage option
You can tune the zmm code generation done by the compiler with the new additional option -qopt-zmm-usage:low|high. The argument value of low provides a smooth transition experience from Intel® Advanced Vector Extensions 2 (Intel® AVX2) ISA to Intel® Advanced Vector Extensions 512 (Intel® AVX-512) ISA on a Skylake server microarchitecture target, such as for enterprise applications. Tuning for ZMM instruction use via explicit vector syntax such as #pragma omp simd simdlen() is recommended. The argument value of high is recommended for applications, such as HPC codes, that are bounded by vector computation to achieve more compute per instruction through use of the wider vector operations. The default value is low for Skylake server microarchitecture-family compilation targets and high for combined compilation targets.
Support Removed
Support for installation on OS X 10.11 or earlier has been removed
Support has been removed for installation and use on these operating system versions. Intel recommends migrating to a newer version of these operating systems.
Support for Xcode* 7.x or earlier has been removed
Alice greenfingers mac free download. Support has been removed for these Xcode versions. Intel recommends migrating to a newer version of these developer toolsets.
Known LimitationsXcode* requires explicit acceptance of Intel bundle at startup for integration to be installed
Beginning with Xcode* 6.3.2, the IDE integration for Intel® Parallel Studio XE does not complete installation until the next time Xcode is started after completing the product installation. When Xcode* is started, you will see a dialog:
The dialog is titled “Unexpected code bundles”, and mentions that Xcode found one or more code bundles not provided by Apple. It then has two buttons, one to “Load Bundles” and one to “Skip Bundles”. “Load Bundles” is required to be clicked to complete the Intel Parallel Studio XE IDE integration. Clicking “Skip Bundles” will cause the Intel tools to not be selectable in Xcode*.
Certain uses of OMP THREADPRIVATE with COMMON block name not diagnosed per OpenMP 4.5 rules
The OpenMP* 4.5 rules states that if a threadprivate directive specifying a common block name appears in one program unit, then such a directive must also appear in every other program unit that contains a COMMON statement specifying the same name. It must appear after the last such COMMON statement in the program unit. The Intel Fortran compiler does not properly diagnose this.
For example, the following program does not conform to the OpenMP* 4.5 specification and ifort does not diagnose and issue an error for the COMMON statements following the OMP THREADPRIVATE statement according to the rule above.
PROGRAM ex1
COMMON /common_blk1/x !$OMP THREADPRIVATE(/common_blk1/)
COMMON /common_blk1/y
COMMON /common_blk1/z
END PROGRAM
Fortran 2008 and Fortran 2015 Feature Summary
The Intel® Fortran Compiler now supports all features from the Fortran 2008 standard. The Intel® Fortran Compiler also supports features from the proposed draft Fortran 2015 standard. Additional features will be supported in future releases. Features from the proposed Fortran 2015 standard supported by the current version include:
