There is a paper "Sparse Extensions to the Fortran Basic Linear
Algebra Subprograms", by Dodson, Grimes, and Lewis which is available,
along with a model implementation in Fortran from the netlib@ornl.gov
in the 'sparse-blas' directory. The paper describes a set of BLAS1
routines for sparse vectors.  It was written in 1985 or 1986.

I am wondering how widely this definition of the sparse-blas1 has
caught on:  What vendors implement it or plan to?  Is there another
formulation which has caught on instead, or is this area still
developing too much to settle on a particular model for the sparse
blas1?

For example, I know that Cray's SCILIB includes routines which
duplicate the functionality of several of the Dodson, Grimes & Lewis
proposal, but have different names and slightly different arrangements
of the arguments.  Maybe these have caught on instead?  (I think they
predate the proposal to which I refer).

Thanks for any light you can shed.
