Hi everyone,
I have just ported my code from a local cluster to larger one which uses
intel mkl and wanted to clarify the changes I've made are the correct
ones wrt the lapacke library:
-- In the local cluster, I had the option
LAPACK_LIBS = lapack lapacke in my .ini file
and used #include "lapacke.h" in the code.
-- In the bigger cluster, I now have to use intel mkl, and I have the
following options in my .cfg
LAPACK_DIR = /apps/compilers/intel/parallel_studio_xe_2016/mkl/lib/intel64
LAPACK_LIBS = -mkl
which will only compile my code if I replace #include "lapacke.h" with
#include "mkl_lapacke.h".
Question: Is this the right way to generalise to mkl lapacke?
Problem: The code runs fine on the local cluster, but breaks (not
obvious where) on the larger one with the above changes. The lapacke
functions seem to work OK at a glance, but seeing as this is the only
thing that has changed this may still be the culprit.
Question: Do I perhaps need to change the lapacke function calls also?
The mkl_lapacke.h header file doesn't seem to give much insight... I
think I remember seeing somewhere calls replaced something like
LAPACKE_dgels -> MKL_LAPACKE_dgels
Thanks!
Chris
