Most of the subdirectories here contain material that was originally distributed through the serial sparse blas SPARKER project, plus a number of extensions of our own design. The original file spblas.f can be downloaded from matisa.cc.rl.ac.uk; of course any bugs in our implementation are our own to fix. The main reference for the serial sparse BLAS is: Duff, I., Marrone, M., Radicati, G., and Vittoli, C. Level 3 basic linear algebra subprograms for sparse matrices: a user level interface ACM Trans. Math. Softw., 23(3), 379-401, 1997. We also include SMMP by Randolph E. Bank and Craig C. Douglas na.bank@na-net.ornl.gov and na.cdouglas@na-net.ornl.gov; we wrapped it in a Fortran 95 interface with dynamic memory allocation.
