AVX so files

Is there a special reason that all avx related .so files (avx, avx2, avx512, vml_avx, vml_avx2, vml_avx512) do not come with a standard .so link, but only as .so.X in the standard intel oneapi hpc toolkit?

Just now with the release of 2022.0.0, this broke our pipeline because it changed from .so.1 to .so.2 and I was already before that release confused that you do not ship it with a link without the number suffix.

Thanks and best wishes,

Miguel

Hi Miguel,

 

Thanks for reaching out to us.

 

Intel oneMKL started adding shared library versioning which was not there till Intel MKL 2020 update 4

 

>>Is there a special reason that all avx related .so files (avx, avx2, avx512, vml_avx, vml_avx2, vml_avx512) do not come with a standard .so link, but only as .so.X ...

 

By versioning the shared libraries, 

 

 >  Allows applications to work correctly in an environment with multiple oneMKL and/or Intel® MKL packages installed

 >  Communicates clearly when incompatible changes are made, and an application should be rebuilt

 >  Allows you to link against a specific version of shared libraries

 

>> it changed from .so.1 to .so.2

The starting version of the shared libraries is '1' and it will be incremented if there are any changes that break backward compatibility.

Please refer to the below link for a detailed explanation regarding the versioning of the shared library.

Hope the provided information helps.
