BTW: Can check if you are using threaded MKL? We default to:
Libraries: -L/cygdrive/c/PROGRA~2/Intel/oneAPI/mkl/2022.1.0/lib/intel64 mkl_intel_lp64_dll.lib mkl_sequential_dll.lib mkl_core_dll.lib If using threaded MKL - try using env variable "OMP_NUM_THREADS=1" and see that makes a difference Satish On Tue, 19 Sep 2023, Barry Smith wrote: > > Can you run in the Microsoft Visual Studio debugger?
