I am trying to solve a matrix 300K x 300K (lines) however my sparse subroutine is running out of memory in the dss_solve-real part of it.</DIV><DIV></DIV><DIV>Overall it works without problem. I am guessing this is too big of a problem?</DIV><DIV></DIV><DIV>Does anybody know how to increase the memory of it?</DIV><DIV></DIV><DIV>I appreciate any suggestions,</DIV><DIV></DIV><DIV>Roberto</DIV><DIV><BR /><H1 class="topictitle1">dss_solve_real<SPAN style="font-size: 11px; font-family: verdana, sans-serif;">MKL_DSS_OUT_OF_MEMORY</SPAN></H1></DIV> Mon, 14 Feb 2011 19:26:56 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Sparse-solver-running-out-of-memory-MKL-DSS-OUT-OF-MEMORY/m-p/801775#M3114 Roberto_Soares 2011-02-14T19:26:56Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Sparse-solver-running-out-of-memory-MKL-DSS-OUT-OF-MEMORY/m-p/801776#M3115 Hi Roberto,<DIV><DIV id="_mcePaste">yes, as I can guess, the task you are solving is very big for 32 bit system . 32bit Pardiso (the same DSS API ) OOC solver cannot solves problems with more than 2 000*10^6 double nonzero elements of L factors, because of 32bit counters inside 32-bit PARDISO ( DSS).workaround - start to work on 64 bit systems which will allow you to solve such tasks.</DIV></DIV><DIV id="_mcePaste">--Gennady</DIV> Mon, 14 Feb 2011 20:23:37 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Sparse-solver-running-out-of-memory-MKL-DSS-OUT-OF-MEMORY/m-p/801776#M3115 Gennady_F_Intel 2011-02-14T20:23:37Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Sparse-solver-running-out-of-memory-MKL-DSS-OUT-OF-MEMORY/m-p/801777#M3116 Hi,<DIV></DIV><DIV>I am back to this problem of running on Win 64 bits to enable larger matrices. I tried to run it yesterday and it didn't work it either.
