Some users are seeing the following error messages when running VASP, built against Intel 2018.0.3.
Intel MKL ERROR: Parameter 4 was incorrect on entry to DSTEIN2.
Intel MKL ERROR: Parameter 6 was incorrect on entry to DSTEIN2
The behavior was noticed as the rank count increased, and https://firstname.lastname@example.org/msg17897.html also suggests that this behavior might be expected as rank count exceeds some level.
Is this expected behavior from MKL, and if so, what is the guidance on MPI rank count vs. matrix property (size?)?
just in the case -- here is the link to the MKL Bug Fix list : https://software.intel.com/en-us/articles/intel-math-kernel-library-2019-bug-fixes# see MKLD-3725 Fixed error: Parameter 6 was incorrect on entry to DSTEIN routine
I can't change the MKL version to the 2019 one. So if I were to keep working with an old MKL version, could you please tell me what causes this error with VASP? Thanks.
