NEW FEATURES (COMPONENT DESCRIPTION)

Intel® oneAPI Fortran Compiler 2022.0

  • The Intel® oneAPI product packages provide two Fortran compilers. Intel® Fortran Compiler Classic (ifort) provides best-in-class Fortran language features and performance for CPU. The Intel® Fortran Compiler (ifx) enables developers needing OpenMP* offload to Intel GPUs. The OpenMP 5.0, 5.1 GPU offload features in ifx are not available in ifort. For calendar year 2022 ifort continues to be our best-in-class Fortran compiler for customers not needing GPU offload support. The default compiler for the Microsoft Visual Studio* environment is ifort.
  • Our latest compiler, the Intel® Fortran Compiler (ifx), is production-ready for CPUs and GPUs. ifx is based on the Intel® Fortran Compiler Classic (ifort) frontend and runtime libraries, but uses LLVM backend compiler technology. In this initial release ifx completely implements Fortran 77, Fortran90/95, Fortran 2003 (except parameterized derived types) and Fortran 2008 (except coarrays) language standards and OpenMP 4.5 and OpenMP 5.0/5.1 directives and offloading features. ifx is binary (.o/.obj) and module file (.mod) compatible. Binaries and libraries generated with ifort can be linked with binaries and libraries built with ifx, and .mod files generated with one compiler can be used by the other (64-bit targets only). Both compilers use the the same runtime libraries. ifx may or may not match performance of ifort compiled applications. Performance and Fortran Standard language improvements will be coming in ifx with each update release throughout 2022.
  • In this release, the ifx version number is 2022.0.0 and the ifort version number is 2021.5.0.

Intel® oneAPI DPC++/C++ Compiler 2022.0

  • The Intel® oneAPI DPC++/C++ Compiler adds new SYCL 2020 features and extensions, and expands its OpenMP 5.x support.
  • New platform optimizations for recently released and upcoming Intel Processors.

For details see Tested Standard C++ API References.
  • This release adds the ability to use OpenMP for thread-level parallelism. Algorithms launched with dpl::execution::par/par_unseq policies can run on top of OpenMP parallel regions, as an alternative to oneTBB or serial execution. This allows developers who already use OpenMP on multicore CPUs to also use oneDPL high-level parallel algorithms in their codes, without introducing extra dependencies and performance risks

Licensing

License Options

Single-Node vs Multi-Node

  • Single-Node: supported for use on laptop, notebook, desktop, PC, or workstation
  • Multi-Node: supported for use on laptop, notebook, desktop, PC, workstation and distributed memory systems ie HPC clusters
    • The applications the developer is writing will determine which option they should purchase

License Types

Named user

  • 10 Workgroup (former 2-seat Concurrent). Support for up to 10 developers
  • 25 Workgroup (former 5-seat Concurrent). Support for up to 250 developers
  • 50 Workgroup. Support for up to 50 developers

With oneAPI Toolkit the need for licenseserver has been removed. Users must be compliant with Intel’s EULA and purchase the number of seats to match the number of users who need to use the software concurrently.

  • Academic
    Degree-granting institutions only; colleges and universities that teach student in higher education towards earning a degree
  • Commercial
    All other users, including government and non-profit institutions that are not degree-granting
  • Languages
    No language selection. Intel oneAPI Base & HPC Toolkit includes both Fortran, C++, Data Parallel C++ and Python compilers in the same SKU.
  • Operating Systems
    All supported OS’s will be included in the same SKU – Windows, Linux, macOS. No OS selection.

Network licenses changes with Intel oneAPI Toolkit

Network licenses (concurrent) are still available as 2 and 5 concurrent user licenses, but these are named differently with oneAPI:

  • 10 Workgroup means up to 10 developers can get support. This license type was previously called 2 Concurrent.
  • 25 Workgroup means up to 25 developers can get support. This license type was previously called 5 Concurrent.
  • 50 Workgroup means up to 50 developers can get support.

I.e. for oneAPI, a maximum number of developers is set for the network licenses, who can then be registered in the IRC and are entitled to request Intel technical support in the confidential Intel Online Service Center. FlexLM is no longer included for the network licenses (as was the case with IPSXE). Licensing and usage restrictions now result from the legal basis (i.e. the license agreement – EULA).

PERFORMANCE ANALYZERS & LIBRARIES

Analyzers (ie VTune Profiler and MPI) and libraries will no longer be available as standalone products.

  • New licenses will only be available through the purchase of oneAPI Base or oneAPI Base & HPC Toolkit Single Node or Multi-Node, depending on the product.
  • Upgrade Promotions to oneAPI are available for existing users with active support

EXISTING USERS – WHAT’S NEXT?

All registered users of Intel Parallel Studio and Intel System Studio (ISPXE or ISS) with active support will receive an email from Intel with the option to upgrade to the oneAPI product corresponding to their existing product free of charge.

  • If the user chooses the free upgrade option, their existing legacy product will be retired, and a new serial number will be issued to the same support end date as their legacy product.
  • Once upgraded to oneAPI, users will be eligible for all version updates & upgrades that Intel releases for oneAPI while their support agreement is active.
  • For continued support, eligible users can purchase oneAPI SSR SKUs
  • If the user does not choose to upgrade to oneAPI, the user can continue using their existing product, but they will not receive any new version updates (unless there are security bug fixes)
  • They will only be able to stay on the version they currently own.
  • Users with active support will continue to have the free upgrade link available to them while support for their license remains active. Once support expires, the free upgrade option will go away.
  • Users who have support in post-expiry renewal range can purchase a post-expiry SSR SKU for their existing product to get their support active. Then, they will receive a link to upgrade to oneAPI for free as part of their service & support agreement.

ONEAPI UPGRADE PROMOTION: AVAILABLE TO IPSXE USERS WITH ACTIVE SUPPORT AT A DISCOUNTED PRICE FOR A LIMITED TIME

  • The Upgrade Promo SKU might be a more cost-effective option for existing Composer Edition users to purchase instead of selecting the free oneAPI Upgrade offer, depending on the type of license they own.
  • Users need to be aware that the Upgrade Promotions are ONLY eligible for purchase BEFORE they click the “Upgrade” to oneAPI if they are currently under active support.
  • Once a user upgrades for free, the upgrade promotion goes away.
  • New Update: IPSXE users who have support which has expired less than 6 months can also purchase a oneAPI Upgrade Promotion SKU.
  • With this purchase, a new serial number will be issued with 12 months of support extended from their current support expiration date.

ONEAPI UPGRADE

  • Upgrade to another suite with additional capabilities, i.e. from oneAPI Base Toolkit to oneAPI Base & HPC Toolkit
  • Upgrade from oneAPI Single-Node to Multi-Node
  • With this purchase, a new serial number will be issued with 12 months of support extended from their current support expiration date.
