topic Hello atsushi, in Intel® oneAPI Math Kernel Library https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/PARDISO-How-to-escape-the-occurrence-of-zero-pivot-error/m-p/1148180#M26890 <P>Hello atsushi,</P><P>Could you tell us more about your setup? Intel MKL PARDISO allows the user to enable pivoting (see iparm[9], iparm[20]&nbsp;at <A href="https://software.intel.com/en-us/mkl-developer-reference-c-pardiso-iparm-parameter">https://software.intel.com/en-us/mkl-developer-reference-c-pardiso-iparm-parameter</A>). What is the matrix type in your test case? If it is for positive definite matrices then your input&nbsp;matrix should not be singular. Are you using matching? So, please give more information about the parameters which you're using for the solver, namely, iparm values and the matrix type.</P><P>Best,<BR />Kirill</P><P>&nbsp;</P> Tue, 12 Feb 2019 05:32:59 GMT Kirill_V_Intel 2019-02-12T05:32:59Z PARDISO, How to escape the occurrence of zero pivot error https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/PARDISO-How-to-escape-the-occurrence-of-zero-pivot-error/m-p/1148179#M26889 <P>Hi everyone,</P><P>I &nbsp;have zero pivot error -4, but I know the error occurs in the condftion of my calculation.</P><P>So I want to have a&nbsp;solution &nbsp;using zero pivot replacement (the value i_parm(10)) and without stopping calculation.</P><P>Is it possible and how should I set parameters?</P><P>&nbsp;</P> Thu, 07 Feb 2019 04:41:11 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/PARDISO-How-to-escape-the-occurrence-of-zero-pivot-error/m-p/1148179#M26889 suzuki__atsushi 2019-02-07T04:41:11Z Hello atsushi, https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/PARDISO-How-to-escape-the-occurrence-of-zero-pivot-error/m-p/1148180#M26890 <P>Hello atsushi,</P><P>Could you tell us more about your setup?
