[Wien] How to free the memory after a parallel session?

[L. D. Marks]

Are you sure the run worked? If not, this might be a source. Otherwise, 
I've been told that this is often normal in Linux and memory will be freed 
up when needed. (There are some kernel tweaks that can be done, but this 
is very system specific.) If you were running mpi and it crashed, 
sometimes "cluster-fork sh /opt/mpich/gnu/sbin/cleanipcs"
will help.

N.B., if everything is working OK, it ain't broke so don't try and fix 
this.

N.N.B., there is an outside chance it could be due to mkl; from 
http://www.intel.com/software/products/mkl/docs/mklusel.htm there is a 
routine MKL_FreeBuffers() which should probably be called before the code
terminates, assuming that you are using mkl.
