Hi all,
I have built C examples that are shipped with MKL OneAPI and it works very well. I executes the example for Pardiso solver that it executed without problem while the residual is very low. The problem is that when in my code I call Pardiso solver, there is no complain but the solution is clearly invalid. I even tried the matrix that is used in the examples and my code fails with very high residual. The settings in iparam for the solver in my case is exactly same as the example.
To find out what the problem can be, I tried to compile the example code myself without using the cmake that is included in OneAPI MKL. I tried to compile the example file like this:
$ icx pardiso_unsym_complex.c -lmkl_core -lmkl_intel_ilp64 -lmkl_intel_thread -liomp5
Using above command, code is compiled and built, but when I execute it, I always get error in symbolic factorization. Again, the example works fine when I execute cmake in the examples/c directory.
Does anyone know if I am missing something? I think the way I compile my own code is somehow wrong so I get very high residuals in the solution. Any guidance is highly appreciated.
Regards,
Dan
