Hi,
I followed this page(https://eigen.tuxfamily.org/dox/TopicUsingIntelMKL.html) to use Eigen::PardisoLLT to solve a sparse linear system(88869x88869). I have MKL(student version) installed. I’ve successfully compiled, linked and run it. However, it’s 5 times slower than Eigen::SimplicialLLT. Am I doing anything wrong there?
Best!
Jing
