Intel Fortran 2024.0.0

Fortran 2023 機能の実装が始まりました。

llvm 版 ifx が正式版となり、VS 統合時のデフォルトコンパイラになりました。従来の ifort は廃止のカウントダウンが始まりましたが、まだ文法機能拡張は続いています。来年予定の次期 Intel Fortran 2025 から ifort は提供されなくなるようです。

今回より Intel Mac 用のインストーラは提供されなくなりました。

Linux 版を apt で install するときは、初期設定からやらないとダメなようでした。 Download the Intel® HPC Toolkit

Intel® Fortran Compiler significantly improves productivity by adding popular LLVM sanitizers allowing developers to catch Fortran, OpenMP*, OpenMP offload address, memory leak, uninitialized memory, thread data races, deadlocks and undefined behavior on CPU.
Intel® Fortran Compiler adds initial Fortran 2023 standards support and enhances OpenMP 5.0, 5.1,and 5.2 and implements initial 6.0 standards compliance.
Updated to include recent versions of 3rd party components, which include functional and security updates.

Corrections to reported problems.
The Intel® Fortran Compiler Classic has been updated to include recent versions of 3rd party components, which include functional and security updates.

Intel Fortran の新機能　

New in Intel® Fortran Compiler and Intel® Fortran Compiler Classic, 2024.0.0 Release

Intel Fortran Compiler (ifx) is the default Fortran compiler when using Microsoft* Visual Studio on Windows.

Initial Fortran 2023 Features

The REDUCE locality spec on DO CONCURRENT
BOZ constants on RHS of INTEGER and REAL assignment statements
BOZ constants as INTEGER and REAL values in PARAMETER statements
BOZ constants as INTEGER or REAL as array constructor values
BOZ constants as INTEGER values in ENUMERATION statements
Intrinsic trigonometric functions returning degrees ACOSD(X), ASIND(X), ATAND(X), ATAN2D(Y, X), COSD(X), SIND(X), and TAND(X)

New OpenMP Features

In ORDERED directives, clause DOACROSS replaces the DEPEND clause.
OpenMP 5.2 classifies some directives as PURE. Only PURE directives are allowed in Fortran PURE procedures. The compiler will issue a message if it detects a non-PURE directive in a PURE procedure.

New OpenMP Features

The MATCH clause is now permitted in the DECLARE VARIANT directive. (OpenMP 5.0)
The DESTROY clause of the DEPOBJ construct now requires a destroy-var modifier (OpenMP 5.1)
The STRICT modifier can now be specified for the GRAINSIZE and NUM_TASK clauses of the TASKLOOP directive. (OpenMP 5.1)
The optional ORDER clause modifiers REPRODUCIBLE and UNCONSTRAINED can be specified for the CONCURRENT argument to specify ordering of iterations of a loop. (OpenMP 5.2)
The ORDER clause may now be specified on the DISTRIBUTE construct. (OpenMP 5.1)
The GROUPPRIVATE directive specifies variables to be shared by the threads of a context group, but each context group has a private copy. (OpenMP 6.0)
You can now specify a DEVICE_TYPE clause on the DECLARE TARGET directive. DEVICE_TYPE (HOST) compiles the body of the construct for host device only,DEVICE_TYPE(NOHOST) compiles the body for the target device, and DEVICE_TYPE(ANY) compiles the body for both host and target. (OpenMP 5.0).
