Intel oneAPI Toolkit 2024 helps accelerate HPC, AI and rendering applications

Intel oneAPI Toolkit 2024 has been release which is a developer tools with new features and enhancements that accelerate HPC, AI and also rendering applications on various platforms, including Intel CPUs, GPUs and AI accelerators. The tools are based on oneAPI, an open and unified programming model that supports C++, OpenMP, SYCL, Fortran MPI and Python. Developers can access the tools from Intel or via popular repositories and containers, and they can also use the Intel Developer Cloud to evaluate the latest Intel hardware and software.

What challenges are developers and ISVs facing?

Many data-centric workloads run best when deployed across a mix of architectures (CPU, GPU, FPGA, AI and other accelerators). However, different architectures typically require unique languages, tools and libraries, adding complexity for developers and limiting code reuse. This makes it difficult to take advantage of multiarchitecture systems and new architectures, optimize application performance, and maintain code efficiently and cost-effectively.

Intel® Software Development Tools help developers build and optimise high-performance applications efficiently through a complete set of advanced compilers, libraries, optimised frameworks, and analysis, debug and porting tools. Built on a legacy with decades of expertise, the tools support:

Familiar languages⎯C, C++, SYCL, Fortran and Python, plus standards including MPI and OpenMP, providing full continuity with existing code.

Intel CPUs, GPUs and FPGAs⎯Enabling unique hardware features such as those for performance, high-bandwidth memory, AI and rendering.

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 laptops, notebooks, desktops, PC, workstations 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 a license server 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 students 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).


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


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.


  • 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 an 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 in Intel oneAPI Base Toolkit

  • Upgrade to another suite with additional capabilities, i.e. from oneAPI Base Toolkit to oneAPI Base & HPC Toolkit
