Is PARDISO indeterministic with MKL_NUM_THREADS > 1


Hello,

Is it possible that PARDISO computes slightly different solutions
when it uses more than one thread?

Best regards,

Andreas Fabri

Hi Andreas, Yes it's possible, especially if your inputmatrix is ill-conditioned. You can find many similar topics into the Forum.
