			== Using a different implementation of BLAS/LAPACK ==

			By default, Matlab uses a version of Intel MKL as its BLAS/LAPACK library. It is possible to manually change this to different libraries, for example BLIS and Flame, which are optimized for AMD processors. The following lines can be added to the batch-script to change it:

			<pre>
			module load numlib/aocl/3.2.0

			export BLAS_VERSION=$AOCL_LIB_DIR/libblis-mt.so
			export LAPACK_VERSION=$AOCL_LIB_DIR/libflame.so
			export BLIS_NUM_THREADS=$SLURM_NTASKS
			</pre>

			This can increase performance depending on the task, for example large matrix multiplications, but caution is advised.
