Pardiso Specify Max CGS Iterations

448 Views

Is there a way to request a new feature to change the maximum number of CGS iterations in the hybrid Preconditioned CGS/CG solve in Pardiso? iparm[3] allows you to change the convergence tolerance and a factorization option. I do not think it it possible to change the maximum number of iterations to meet the convergence criterion. I think this could be done in iparm[3] by doing: iparm[3]= 1000*MaxIts+10*L+K, rather than its current form iparm[3]= 10*L+K. Seems easy?
