But in spite of the value of iparm(6) PARDISO uses vector x for calculation the solution (see description of the parameter in MKL manual).Because DSS is the interface to PARDISO,your approach by passing the same pointer as b and x vectors could produce wrong results.<BR /><BR />With best regards,<BR />Sergey</DIV> Mon, 04 May 2009 08:56:45 GMT Sergey_P_Intel2 2009-05-04T08:56:45Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Can-dss-solve-real-store-the-results-back-to-the-input-vector/m-p/910171#M12078 I see PARDISO can do this using iparm(6)=0. But can I do it with dss_solve_real too but simply passing the same pointer as both RHS and solution vectors? <DIV><BR /></DIV> <DIV><BR /></DIV> Sun, 03 May 2009 09:10:17 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Can-dss-solve-real-store-the-results-back-to-the-input-vector/m-p/910171#M12078 crispybits 2009-05-03T09:10:17Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Can-dss-solve-real-store-the-results-back-to-the-input-vector/m-p/910172#M12079 <DIV style="margin:0px;">Hi kallog,<BR /><BR />Some note: PARDISO can do this using iparm(6)=1.
