https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Exceptions-thrown-in-MKL/m-p/987888#M17863 Hi,<BR /><BR /> I'm having a problem with exceptions in MKL: I wrote some code that will calculate the eigenspace of a matrix. <BR />With small matrices it works fine and the results are correct, but when I am trying larger matrices (approximatly 4000 by 4000 double entrys) the program terminates with an uncaught exception thrown somewhere in dsytrd.<BR /><BR />I would like to catch this exception and give the user some feedback (like "out of memory"), but I don't know what to catch - I am catching std::exception but that doesn't help. The exception that's thrown by MKL always passes to the catch (...) clause and there I cannot tell the user anything detailed about what happened.<BR /><BR />Is there some documentation I missed that describes what kind of exceptions are thrown by MKL?<BR /><BR /><BR />Thanks in advance,<BR /> Sebastian<P>Message Edited by SebastianD on <SPAN class="date_text">06-23-2005</SPAN> <SPAN class="time_text">03:42 PM</SPAN></P> Fri, 24 Jun 2005 05:41:12 GMT sebastiand 2005-06-24T05:41:12Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Exceptions-thrown-in-MKL/m-p/987888#M17863 Hi,<BR /><BR /> I'm having a problem with exceptions in MKL: I wrote some code that will calculate the eigenspace of a matrix. <BR />With small matrices it works fine and the results are correct, but when I am trying larger matrices (approximatly 4000 by 4000 double entrys) the program terminates with an uncaught exception thrown somewhere in dsytrd.<BR /><BR />I would like to catch this exception and give the user some feedback (like "out of memory"), but I don't know what to catch - I am catching std::exception but that doesn't help.

Could you try to set the environment variable MKL_DISABLE_FAST_MM to 1 before starting your application?</DIV> <DIV></DIV> <DIV>Also, could you tellwhich version of MKL you're using, whichprocessor andOS, how much memory you have?</DIV> <DIV></DIV> <DIV>Michael.</DIV> Fri, 24 Jun 2005 15:44:21 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Exceptions-thrown-in-MKL/m-p/987889#M17864 michael_chuvelev 2005-06-24T15:44:21Z
