Hello MKL tech support,
I have a positive definite matrix and using Pardiso to solve the problem. I kept receiving the error -4 for the solver. It is interative refinement problem in phase 33.
My params for pardiso are:
iparm[7] = 15;
iparm[10] = 0;
iparm[12] = 0;
iparm[0] = 1;
iparm[1] = 0;
iparm[3] = 0;
iparm[4] = 0;
iparm[5] = 0;
iparm[6] = 0;
iparm[9] = 13;
iparm[11] = 0;
iparm[13] = 0;
iparm[17] = -1;
iparm[18] = 0;
iparm[19] = 0;
iparm[20] = 0;
iparm[26] = 1;
iparm[27] = 0;
iparm[34] = 1;
iparm[59] = 0;
I am trying to solve Ax = y but there was no error in the factorization phase until the phase 33.
Thanks,
