about parallelism on BLAS level-1 routines and VML

Hi all,

I am running BLAS routines in MKL with intel compiler (icpc). Following the example given in the compiler, I try to set the numbers of threads from 1 to 10 while running dgemm routine for matrix-matrix multiplication and I saw the speedup while increasing the number of threads. However, for level-1 routines (e.g. cblas_zcopy, cblas_zaxpby), I didn't see any speed up for multithreading version. I wonder if there is any multi-threading version for level-1 routines or not? What about the VML routines? I also try to use those routines (e.g. vzExp, vzMul) but no speedup at all in multithreading environment.
