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. -- David Bernholdt bernhold@qtp.ufl.edu Quantum Theory Project bernhold@ufpine.bitnet University of Florida Gainesville, FL 32611 904/392 6365
