https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/cblas-dtrsm-use-case-race-condition/m-p/993651#M18168 <P>Hello,</P> <P>I use cblas_dtrsm heavily as part of my application and in some cases need to solve a system where the right hand side is a column of the matrix itself and I would like to get&nbsp; the result stored within the matrix itself i.e. Rx=x where x=R_{k} i.e. x is the column vector k of the matrix. Is this possible without getting race conditions or corrupted matrix R? In my case k is always the last column of the matrix. This will help me squeeze every bit of performance by avoiding an extra copy and allocation for each invocation of this use-case.</P> <P>Many TIA,</P> <P>Best regards,</P> <P>Giovanni</P> Fri, 21 Sep 2012 15:54:25 GMT Azua_Garcia__Giovann 2012-09-21T15:54:25Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/cblas-dtrsm-use-case-race-condition/m-p/993651#M18168 <P>Hello,</P> <P>I use cblas_dtrsm heavily as part of my application and in some cases need to solve a system where the right hand side is a column of the matrix itself and I would like to get&nbsp; the result stored within the matrix itself i.e. Rx=x where x=R_{k} i.e. x is the column vector k of the matrix.
