I just updated my bjam. So how the see the information you mention here 
(i.e. the properties used to build the 'algorithm' target) ?

I thought that the 'algorithm' target would inherit the 
<parallelism>fake feature because it links to the 'libfemtown_std' 
library which is build with the '<parallelism>fake' feature.
But also adding <parallelism>fake to the requirements of the 'algorithm' 
target still does not result in linking 'algorithm' with the fake-mpi 
library ?!

The funny thing is that in my small test-case that I used previously 
everything works fine. There I just created a library with the 
<parallelism>fake feature and used this library in my exe target. This 
resulted in linking the exe with the fake-mpi library.

To bypass the problem I can of course just explicitly state which 
library I want to use when linking my exe but I'm trying to use the 
boost-build language correctly.
