oneAPI Licensing

The licensing and the naming of the editions have changed with the launch of oneAPI.

Supported platforms

Intel oneAPI Base & HPC Toolkit is offered with support for Windows and Linux. Support for both platforms are included with each license.


Intel oneAPI Base & HPC Toolkit is offered with support for Fortran, C++ and Data Parallel C++. Support for all described languages is included with each license.


Intel oneAPI Base & HPC Toolkit is offered in two editions: Single-Node and Multi-Node.

The target platforms for development and deployment can range from a workstation to a multi-node cluster requiring different support efforts. Choose the paid product with the support that best fits the used model targeted:

  • Intel® oneAPI Base and HPC Toolkit Single-Node: Target platform of shared memory systems including PCs, laptops, or workstations.
  • Intel® oneAPI Base and HPC Toolkit Multi-Node: Target platform of shared memory systems such as PCs, laptops, workstations, or distributed memory high-performance compute clusters.
Transition from IPS to Intel oneAPI

Converting from Intel Parallel Studio to oneAPI Base and HPC Toolkit

When upgrading, a new serial number is generated for the oneAPI license and the previous IPSXE serial number is marked as “retired”. All IPSXE owners will still be able to use all of their IPSXE tools after the upgrade.

In addition, these IPSXE licenses are in most cases not only extended to include new components, but they also usually gain a complete tool suite including C ++ and Fortran compilers (both!) for an additional operating system.

If you have, for example, IPSXE Composer Edition for Fortran, Windows with active support, as a result of the transition to the Intel® oneAPI Base & HPC Toolkit, you will also receive a license for use under Linux, which then also includes the Intel Fortran Compiler and the MKL for Linux.

Intel also offer a special bundle for Fortran users.  Intel Fortran Compilers includes; the new LLVM based Intel Fortran Compiler (ifx), the Intel Fortran Compiler Classic (ifort), and Math Kernel Library – for Windows or Linux. The new Intel Fortran Compilers suite give existing Parallel Studio XE Composer for Fortran users with current support the choice to upgrade to Intel Fortran Compilers OR to oneAPI Base & HPC Toolkit (Single-node), depending what componets the developer is in need of.

Are you a current Intel Parallel Studio XE user? To minimize the cost and make the transition to oneAPI as smooth as possible, contact Alfasoft BEFORE you upgrade your license in IRC.

Why should you use oneAPI HPC?

With 48% of developers targeting heterogeneous systems that use more than one kind of processor*, more efficient multiarchitecture programming is required to address the increasing scope and scale of real-world workloads.

Using oneAPI’s open, unified programming model with Intel’s standards-based multiarchitecture tools provides freedom of choice in hardware, performance, productivity, and code portability for CPUs and accelerators. Code written for proprietary programming models, like CUDA, lacks portability to other hardware, creating a siloed development practice that locks organisations into a closed ecosystem.

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 for oneAPI HPC

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 HPC 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 the 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 HPC 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.
