MKL 2021.1.1 PARDISO Failures with TBB 4.4.3: Version Compatibility Issue?

[Piyush17]

I'm currently migrating our application's dependencies to newer versions and have upgraded from Intel MKL v11.3 to v2021.1.1. However, we're still using Intel TBB v4.4.3 (not yet migrated to the newer TBB version).

After this partial upgrade, we're experiencing failures when calling the PARDISO solver function. Specifically, we see the error "Zero pivot, numerical factorization problem" in approximately 3-4 cases out of 1,000 calls.

I've found some information suggesting that MKL v2021.1.1 requires TBB versions from the 2021.x series for full compatibility. Before proceeding with a TBB upgrade, I'd like to confirm:

1. Is the incompatibility between MKL 2021.1.1 and TBB 4.4.3 likely causing these PARDISO failures?
2. Is upgrading TBB mandatory when using MKL 2021.1.1, or are there configuration settings that could resolve this issue?

Any guidance or official documentation references would be greatly appreciated.

Hi,

Using old versions of libraries is very likely to cause problems. To see which compiler and TBB versions are compatible with MKL 2021 please check Intel® oneAPI Math Kernel Library 2021 System Requirements.
