We are cooperating with Iain Duff, Roger Grimes and John Lewis to provide a WWW-based distribution mechanism for Release II of the Harwell-Boeing Sparse Matrix Collection. Release II is a significant generalization of Release I, and we expect that some of our database mechanisms will need to be expanded to accommodate it. Our plans are to make Matrix Market the primary archive for the collection, with mirrored copy on netlib. We expect that Release II will be in place later this year.
There are a variety of additional facilities which could enhance a service such as Matrix Market. In the remainder of this section we discuss several of these in more detail.
