Thanks for the reply. I have not tried ggev. The documentation describes it as the same as ggevx without extra options for balancing and so forth. ggev3 is not in the MKL that I currently have installed. How is it different?
I'm sorry for the late reply. Indeed, the difference between all the mentioned solvers isn't so significant.
So, in order we to take a look at your issue, can you please provide us with a reproducer and specify which MKL version you have.
