New and Changed Features

The Intel® Software License Manager has been updated to version 2.9 for this release. Gba emulator mac. You must upgrade to this version before installing Intel Parallel Studio XE 2019 Update 4 with a floating license. Please refer for more details:

Intel® Software License Manager Download
Intel® Software License Manager Release Notes

Please refer here for more details.

Currently '#pragma omp simd' overrides FP value and exception safe settings. The following options change that legacy behaviour and produce value and exception safe code even for SIMD loops.

Qsimd-honor-fp-model[-]: Tells the compiler to obey the selected floating-point model when vectorizing SIMD loops
Qsimd-serialize-fp-reduction[-]: Tells the compiler to serialize floating-point reduction when vectorizing SIMD loops.

OpenMP SIMD specification and FP model flag can contradict in the requirement. Compiler’s default is to follow OpenMP specification and vectorize the loop. With this new flag, programmer can override so that the compiler follows the FP model flag instead and serialize the loop
Note1: When –qsimd-honor-fp-model is used and OpenMP SIMD reduction specification is the only thing causing serialization of entire loop addition of qsimd-serialize-fp-reduction will result in vectorization of the entire loop except reduction calculation which will be serialized.
Note2: This option does not affect auto-vectorization of loops.

code names supported :cascadelake, kabylake, coffeelake, amberlake, whiskeylake.

Explicit syntax for dynamic alignment
#pragma vector dynamic_align[(pointer)] #pragma vector nodynamic_align
With no pointer specified, compiler behaves normally (automatically decides which pointer has to be aligned or doesn’t generate peel loop at all). With pointer specified, compiler generates peel loop for that pointer. With nodynamic_align clause, the compiler will not generate a peel loop.
#pragma vector vectorlength(vl1,vl2, . , vln)
#pragma vector vectorlength(vl1,vl2, . , vln)
Vectorizer chooses best vector length from the list according to cost model. If all vector length from the list are not profitable, the loop remains scalar. This pragma doesn’t force vectorization, thus it can be safely used for all loops.

Language features from the OpenMP* Technical Report 6 : Version 5.0 Preview 2 specifications are now supported.

Explicit syntax for inclusive scan *
#pragma omp simd[parallel] scan(scan-op: item-list) #pragma omp inclusive_scan(item-list)
Explicit syntax for exclusive scan *
#pragma omp simd[parallel] scan(scan-op: item-list) #pragma omp inclusive_scan(item-list)
Prefix sum is computed correctly during vector execution
*The syntax will be renamed in product release
UDI for OpenMP* Parallel pragmas
#pragma omp declare induction ( induction-id : induction-type :step-type : inductor ) [collector( collector )]

For more information, see the compiler documentation or the link to the OpenMP* Specification above.

The Intel® C++ Compiler 19.0 supports the following features under the /Qstd=c++17 (Windows*) or -std=c++17 (Linux*/macOS*) options:

Fold expressions(N4295)
Inline variables(P0386R2)

Canary bytes are cleared right after read with /GS by default/
New -xcannonlake option
New -mtune=cannonlake option
-rcd option enabled “fast” float-to-integer conversions, by using round-to-nearest instead of truncating rounding. This option has been deprecated.

For a list of deprecated compiler options, see the Compiler Options section of the Intel® C++ Compiler19.0 User's Guide.

Parallel STL for parallel and vector execution of the C++ STL

Intel(R) C++ Compiler is installed with Parallel STL, an implementation of the C++ standard library algorithms with support for execution policies.

Features/APi changes

More algorithms support parallel and vector execution policies: find_first_of, is_heap, is_heap_until, replace, replace_if.
More algorithms support vector execution policies: remove, remove_if.
More algorithms support parallel execution policies: partial_sort.

To learn more, please refer to article https://software.intel.com/en-us/get-started-with-pstl

Support Deprecated

Intel® Cilk™ Plus is a deprecated feature since Intel® C++ Compiler 18.0. For more information see Migrate Your Application to use OpenMP* or Intel® Threading Building Blocks (Intel® TBB) Instead of Intel® Cilk™ Plus

Support Removed

Removed support for 32 bit applications on macOS

Starting with the 19.0 release of the Intel® Fortran Compiler, macOS 32-bit applications are no longer supported. If you want to compile 32-bit applications, you should use an earlier version of the compiler and Xcode* 9.4 or earlier.

Known Limitations

Xcode 10 new build system not supported

The Xcode 10 Beta introduced a “New Build System (Default)” which currently do not support custom compilers.You will see the error 'no rule to process file' when building an Intel C++ Compiler project within XCode 10 To use Intel compilers, switch to “Legacy Build System” in Project Settings.

Parallel STL

unseq and par_unseq policies only have effect with compilers that support '#pragma omp simd' or '#pragma simd. Parallel and vector execution is only supported for a subset of algorithms if random access iterators are provided, while for the rest execution will remain serial. Depending on a compiler, zip_iterator may not work with unseq and par_unseq policies.

Building Tachyon
For building from Xcode*, you may run into problems building the build_with_tbb configuration with llvm gcc*. The problem will be that the libtbb.dylib cannot be found. In this case, go to the Summary->Linked Frameworks and Libraries section, and manually add the libtbb.dylib library from the <install-dir>/tbb/lib directory

Technical Support

New and Changed Features

The following features are new or significantly enhanced in this version. For more information on these features, please refer to the documentation.

KNL and Atom targets unsupported on OS* X. Disabled options on OS* X are the following:

-xATOM_SSE4.2
-xATOM_SSSE3 –xBETA_B
-xMIC-AVX512 -xBETA_R3 –xKNL

The same options with –ax will be disabled too. Driver should issue error message in case any of these options are used on OS* X.

A list of compiler header files are moved to a subfolder of existing include folder. There is no change needed to source code that uses the C++ Compiler headers. The new subfolder will be searched during compilation automatically by the compiler driver.

For C++ AOS layout, there is no existing language extensions for programmers to annotation the AOS->SOA conversion to minimize gather/scatter generation while vectorizing the SIMD loop/functions.
SDLT primitive template V2 supports n-D Containers; it is designed and implemented by using C++11 feature which supports a set of primitives/methods to convert n-D AOS layout to n-D SOA layout.

Support for more new features from OpenMP* 4.0 or later

Support for #pragma omp for linear (list [ : linear-step ])
- where list is either list or modifier(list)
Support for ref, val, and uval modifiersfor the linear clause
- Examples: linear(ref(p)), linear(val(i):1), linear(uval(j):1)
Support for #pragma omp simd simdlen(n)
Support for #pragma omp ordered [simd]
Reductions over whole arrays: int x[n]; #pragma omp simd reduction(+:x)
Intel® processor clause extension added to #pragma omp declare simd (proposed; not officially part of OpenMP* 4.5)
support for clauses SIMD and NONMONOTONIC modifiers for #pragma omp for schedule :
- The Intel® C++ Compiler 17.0 include SIMD and NONMONOTONICmodifiers extenstion to schedule clause to enhance user control of how interations of the for loop are divided among threads of team. See the Intel® C++ Compiler User’s Guide for more details.
support for array sections as list items in the reduction clause
- reduction(reduction-identifier:list) If a list item is an array section, it is treated as if reduction clause is applied to each seperate element of the section. The elements of the private array sections will be allocated contiguously

Annotated source listing

This feature annotates source files with compiler optimization reports. The listing format may be specified as either text or html. The location where the listing appears can be specified as the caller site, the callee site, or both sites.

New attribute, pragma, and compiler options for code alignment

New attribute __attribute__((code_align(n))) is provided to align functions to a power-of-two byte boundry n
New pragma #pragma code_align [(n)] is provided to align the subsequent loop head to a power-of-two byte boundry n
New compiler option -falign-loops[=n] is provided to align all loops to a power-of-two byte boundry n, or to provide no special alignment for loops -fno-align-loops (the default)

C++14 features supported

The Intel® C++ Compiler 17.0 supports the following features with compiler option /Qstd:c++14 (Windows*) or -std=c++14 (Linux*/macOS*)

Support C++14 variable templates (N3651)
Support C++14 relaxed (aka extended) constexpr (N3652)
Support C++14 sized deallocation (N3663)
Please see C++14 Features Supported by Intel® C++ Compiler for an up-to-date listing of all supported features, including comparisons to previous major versions of the compiler.

C11 features supported

The Intel® C++ Compiler 17.0 supports the following features with compiler option /Qstd:c11 (Windows*) or -std=c11 (Linux*/macOS*)

Support for all C11 features except C11 keyword _Atomic and __attribute((atomic))
Please see C11 Support in Intel® C++ Compiler for an up-to-date listing of all supported features, including comparisons to previous major versions of the compiler.

-ansi-alias compiler option is now the default

-ansi-alias is now the compilation default. This option tells the compiler to assume that the program adheres to ISO C Standard aliasability rules. If your program does not adhere to ANSI aliasability rules, this option may cause the compiler to generate incorrect code. In this case, you can specify -no-ansi-aliasto ensure program correctness.

New and Changed Compiler Options For details on these and all compiler options, see the Compiler Options section of the Intel® C++ Compiler 17.0 User's Guide.

-f[no-]align-loopsAligns loops to a power-of-two byte boundary.
-fp-model consistentEnables consistent, reproducible results for different optimization levels or between different processors of the same architecture
-qopt-report-annotateEnables the annotated source listing feature and specifies its format
-qopt-report-annotate-position[=keyword]Enables the annotated source listing feature and specifies the site where optimization messages appear in the annotated source in inlined cases of loop optimizations.

C++ Compiler For Mac Os X

For a list of deprecated compiler options, see the Compiler Options section of the Intel® C++ Compiler 17.0 User's Guide.

Compiler options starting with –o are deprecated
All compiler options starting with –o are deprecated. These will be replaced by new options preceded with –q. For example, -opt-report should now be –qopt-report. This is to improve compatibility with third-party tools that expect –o<text> to always refer to output filenames.

Change in defualt behatviour of offload DEFAULTMAP

DEFAULTMAP (TOFROM:SCALAR) Local scalars do not offload by default, need “default map: scalar” clause
Causes a scalar variable to be treated as if it appeared in a MAP clause with a map-type of TOFROM . If this clause is not specified, a scalar variable is not mapped; instead it has an implicit attribute of FIRSTPRIVATE . At most one DEFAULTMAPclause can appear in the directive.

Open MP helper thread removed

The openMP monitor thread which was used for book-keeping during program execution has been removed. However, the thread itself is user-visible with Vtune or other tools.

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 Intel® Xeon® Platinum processor (formerly code name Skylake), 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 Intel® Core™ /Intel® Many Integrated Core Architecture (Intel® MIC Architecture) Intel® AVX-512 combined compilation targets.

Support Removed

Support for installation on OS X 10.10 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.

Known Limitations

Support for OS X* 10.11

OS X* 10.11 introduces a new security policy called System Integrity Protection (SIP). This significantly impacts certain installation scenarios. Please see OS X* 10.11 Support in Intel® Parallel Studio XE 2016 for important information before attempting to install on OS X* 10.11

Xcode* 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*.

Incompatible with the default libc++ library
Some applications are incompatible with libc++, which is currently enabled as default C++ library in the Intel® C++ Compiler 17.0. For example, the 435.gromacs and 447.dealII from SPEC CPU2006 suite.
Please use -stdlib=libstdc++ to compile such applications.

Creating new project in Xcode* causes hardcoding of –stdlib=libc++
A new project created in Xcode* causes the hardcoding of a setting for -stdlib=libc++ even for projects that have the Intel® C++ Compiler toolset added. So setting the Intel® C++ Compiler field for the C++ Standard Library setting to libstdc++ is ineffective because libc++ overrides the setting. To change this, do the following:
1. Select the project row in the navigator area at the left of the workspace window
2. In the project editor that appears, select the row that represents the project level of build settings
3. You should see the C++ Standard Library setting in bold, indicating that it has a custom value in this project
4. Select that row and press the Delete key to remove the customized value
5. The C++ Standard Library build property should now have the value Compiler Default
Note that you may have to follow the above steps before adding the Intel® C++ Compiler toolset to your project build rules.

Spurious error when a call to a template dependent function is made in a decltype expression in an out-of-line definition for a late-specified return type

This is a known regression in Intel® C++ Compiler 16.0 Update 2. An example is:
To work around this problem, the definition can be moved inline, or the use of a late-specified return type should be avoided (by explicitly declaring the return type).

Boost issue with c++14 relaxed constexpr

If you are using Boost in -std=c++14 mode and you see compilation errors that seem to be related to the constexpr feature, try defining BOOST_NO_CXX14_CONSTEXPR in boost_1_59_0/boost/config/compiler/gcc.hpp. To do this you should change these lines (around line 256):
#if !defined(__cpp_constexpr) (__cpp_constexpr < 201304)
# define BOOST_NO_CXX14_CONSTEXPR
#endif
to:
//#if !defined(__cpp_constexpr) (__cpp_constexpr < 201304)
# define BOOST_NO_CXX14_CONSTEXPR
//#endif
