Dear all,
The attached example tries to call dss_reorder for 29x29 symmetric matrix. The call to dss_reorder never ends. I have no idea what is wrong. The matrix is symmetric, having zeros in the right lower block as it comes from saddle problem. I wanted to attach a shell script compiling the attached example, but this chat does not like its extension, so here is the way how I compiled it:
MKLROOT=/opt/intel/mkl
MKLPATHINC=$MKLROOT/include
MKLPATHLIB=$MKLROOT/lib/intel64
COMPOSERLIB=/opt/intel/composerxe/lib/intel64
LD_FLAGS="-Wl,--start-group $MKLPATHLIB/libmkl_intel_lp64.a $MKLPATHLIB/libmkl_intel_thread.a $MKLPATHLIB/libmkl_core.a -Wl,--end-group $COMPOSERLIB/libiomp5.a -lpthread -lstdc++ -lm"
c++ -g test_mkl_dss.cpp -o test_mkl_dss -I${MKLPATHINC} $LD_FLAGS
