Take a look at
the Vector, Signal and Image Processing Library (VSIPL) home page:

	http://www.vsipl.org/

    HPEC-SI CONTRIBUTES TO EXTENSION OF VSIPL 
    The High Performance Embedded Computing Software Initiative,
    sponsored by the U.S. Dept. of Defense
    and its High Performance Computing Modernization Office,
    is further advancing the development
    of embedded computing software standards
    with a goal of software portability:
    to enable "write-once/run-anywhere"
    for applications of high performance embedded computing.
    The VSIPL Forum is cooperating with HPEC-SI
    in the development of proposals for "VSIPL++",
    a C++ binding for VSIPL, and a "parallel VSIPL++"
    for multiprocessor systems.

The GSL and the VSIPL are very similar.
The VSIPL has a much narrower scope than the GSL
but parallel VSIPL++ will use
the Message Passing Interface (MPI) standard.
