Hi

I just started using v10.2 update 2 and found that for mytpe =2, PARDISO reports the number of equation when it detects a zero:

*"iparm(30) - the number of equation where PARDISO detects zero or negative pivot for MTYPE=2 (real positivedefinite matrix) and MTYPE=4 (complex and Hermitian positive definite matrices). If the solver detects a zero or negative pivot for these matrix types, the factorization is stopped, PARDISO returns immediately with an error (error = -4) and iparm(30) contains the number of the equation where the first zero or negative pivot is detected."*

As far as I remember, PARDISO does an internal equation ordering for the given matrix. I just want to know the reported Equation # is the equation number associated with PARDISO's internal ordering or the equation number referring to my original matrix. The former really deos not help since we have no idea how the PARDISO internally orders equations. Thus, what I really need is the one that refers to the order given with the original matrix.
