https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Pardiso-Specify-Max-CGS-Iterations/m-p/1145098#M26643 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?
