Intel oneAPI Base Toolkit

The Smart Path to Accelerated Computing without the Economic and Technical Burdens of Proprietary Programming Models 
base toolkit rgb 3000


Accelerate data-centric workloads by developing high-performance applications that scale across a variety of architectures (CPUs, GPUs, FPGAs) using a single programming model. With oneAPI’s open standards-based path to accelerated computing and the Intel® oneAPI Base Toolkit, get all you need: a cross-architecture language Data Parallel C++ along with C++ and Python, best-in-class compilers, performance libraries, advanced analyzers and debugger, and a CUDA code migration tool. Break away from proprietary single-architecture languages and deliver parallel programming productivity with uncompromised performance for Intel® CPUs and accelerators. Take advantage of Priority Support for fast development with direct access to Intel engineers for technical questions.

Note: Intel oneAPI Base Toolkit is a limited version of oneAPI recommended for no-legacy users that focus on Data Parallel C++ and C++ development only. For existing Intel Parallel Studio customers we recommend the Intel oneAPI Base & HPC Toolkit. To upgrade your Intel Parallel Studio XE license, contact Alfasoft for oneAPI Promo Upgrade Price.

• Concurrent 5-seat: any 5 concurrent users / up to 25 registered developers
     o No more Floating 1-seat option
     o FlexLM will no longer be included
           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 – for degree-granting institutions only; colleges and universities who teach student in higher education towards earning a degree
• Commercial – for all other users, including government and non-profit institutions who are not degree-granting

Languages: No language selection. Intel oneAPI Base & HPC Toolkit will include both Fortran & C++ compilers in the same SKU.

OS: all supported OS’s will be included in the same SKU - Windows, Linux, macOS. No OS selection.

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.
     o Once upgraded to oneAPI, users will be eligible for all version updates & upgrades that Intel releases for oneAPI while their support agreement is active.
     o 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)
     o 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 current under active support.
     o Once a user upgrade 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, ie 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.
