Hi,
I'm wondring if the soubroutine zgbmv is multithreaded in mkl, because i test use intel/mkl/64/10.3/2011.5.220 with intel-compiler and i noticed that there is no multithreding in it
I compile with this :
ifort myapp.f -L$BLASDIR -I$INCLUDE -I$INCLUDE/intel64/lp64 $BLASDIR/libmkl_blas95_lp64.a
$BLASDIR/libmkl_lapack95_lp64.a -Wl,--start-group $BLASDIR/libmkl_intel_lp64.a $BLASDIR/libmkl_intel_thread.a
$BLASDIR/libmkl_core.a -Wl,--end-group -liomp5 -lpthread -shared-intel -mcmodel=medium -o myapp.e
export MKL_NUM_THREADS=4; ./myapp.e
when i launch the top command and ctrl H, i have one instance of the program intead of four
Red
Thanks in advance

Hello
yes, that's right. this routine is not threaded. You can find the list of threaded routines into User's Guide, see section "Threaded Function and Problems"
