https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/some-notes-for-Pardiso-users/m-p/888223#M10171 some notes for Pardiso OOC users:<BR /><BR />Recently we received multiple inputs from our customers that 32bit Pardiso Out-of-Core (OOC) solver crashes when solving a big task. <BR />These failures are related to the fact that the memory needed for numerical factorization stage, one of Pardiso stages, exceeded 2Gb. <BR />2 Gb roughly corresponds to the memory that is allocated at the factorization stage for 250*10^6 double nonzero elements.<BR />This gives the current implementation limitation. <BR />Please, be aware that for big input matrices, if at the factorization stage they generate around or more then 250*10^6 nonzero elements Pardiso will crash because of out-of-memory. <BR /> Mon, 24 Aug 2009 05:56:49 GMT Gennady_F_Intel 2009-08-24T05:56:49Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/some-notes-for-Pardiso-users/m-p/888223#M10171 some notes for Pardiso OOC users:<BR /><BR />Recently we received multiple inputs from our customers that 32bit Pardiso Out-of-Core (OOC) solver crashes when solving a big task. <BR />These failures are related to the fact that the memory needed for numerical factorization stage, one of Pardiso stages, exceeded 2Gb. <BR />2 Gb roughly corresponds to the memory that is allocated at the factorization stage for 250*10^6 double nonzero elements.<BR />This gives the current implementation limitation. <BR />Please, be aware that for big input matrices, if at the factorization stage they generate around or more then 250*10^6 nonzero elements Pardiso will crash because of out-of-memory. <BR /> Mon, 24 Aug 2009 05:56:49 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/some-notes-for-Pardiso-users/m-p/888223#M10171 Gennady_F_Intel 2009-08-24T05:56:49Z
