Is there any way to get 32bit MKL source for Windows?

[DanM27]

I'm attempting to update our MKL libraries to MKL 24.2 on Windows for a 32bit application. The most recent MKL user guide (for 24.2), has a whole section "Detailed Structure of the IA-32 Architecture Directories" (page 182) that describes files that don't appear in my recent MKL installation, and I can't find any download options or installation options for 32bit (mkl_intel_c.lib, for example).

Could you provide me with a link to download MKL 24.2 for 32 bit systems? We plan to upgrade to 64bit in the future, but it is not an option for us in the near term. Thanks in advance!

If I interpret the "Deprecation Notice" correctly (it's 2 posts above yours), you either have to stick to the 2023 MKL, or bite the bullet and move to 64-bit. We did the latter 10+ years ago and never looked back

Regards,

Hi Jörn, thanks for responding.

We'd very much like to stick to the 2023 MKL for 32bit, but we can't find a link to download it anywhere. We're currently using a release of MKL from about 15 years ago, so we're really just looking for any MKL 32 bit source from the last 5 years or so.

Best,

Dan

Hi Dan,

Thank you for posting in the forum!

The 32-bit binaries have been deprecated in oneMKL 2024.0 and removed since the recent 2025.0 release. Access to older versions can be found in the Intel Registration Center for users who have priority support. 

Best,

Fengrui

Does the oneAPI base tookit 2024.2 download (which includes MKL 2024.2.1) include 32-bit libraries for MKL? I installed but don't see them and expected to find 32-bit libraries in the installation.

Intel oneMKL 2024.2  (part of oneAPI 2024.2) was the last one version included 32-bit support. But please know that there wasn't oneMKL 2024.2 32-bit standalone package. The 32-bit libraries were packaged in Intel oneAPI Base Toolkit for Windows (32 bit)

For example:

Note: This 32-bit package is an add-on that requires Intel® oneAPI Base Toolkit for Windows* (64-bit) to be installed first. 

If you need download the older version(Intel oneAPI Base Toolkit v. 2024.2for both 64-bit and 32-bit), please submit a support ticket through Online Service Center.  Attached the guidance here: How to Create a Support Request

You obviously make the "oneAPI Base Tookit 2024.2.1" available in 64-bit.

Can you please also make the "oneAPI Base Toolkit (32-bit) 2024.2.1" available?

Please visit Intel® Toolkits, AI Tools, Compilers Supported Product Versions to get the product versions(Intel® oneAPI Base Toolkit for Windows* (32-bit) v2024.2.1) through priority support.
